Trusted by developers
building real AI systems

GenAI Accelerator by Datalumina is an outstanding course. Having previously worked with the OpenAI API and already familiar with prompt and RAG concepts, I initially thought I had a solid grasp of the essentials. Nevertheless, I felt there had to be something more to it — it couldn’t just be as simple as that. This course proved me right. Dave Ebbelaar does a fantastic job explaining complex ideas with exceptional clarity. The techniques covered, both in prompting and RAG, go far beyond what I had imagined. Moreover, the workflow design using the GenAI Launchpad (another Datalumina course included) and the insights on deployment adds tremendous value — even for someone like me, with over 30 years of development experience in the Microsoft ecosystem. To anyone unsure about taking this course: it's an absolute must — not just for those involved in AI projects or looking to get into AI, but also for anyone interested in creating powerful solutions that don't necessarily even involve AI. The skills learned here can be applied to a wide range of problem-solving. Thank you to Dave and the team for sharing your expertise and helping me level up my skills — this knowledge will certainly stay with me for a long time.

The GenAI Accelerator is a clear, well-structured program that teaches you skills you can directly apply to real-world projects. Forget shallow YouTube tutorials with throwaway snippets, this is real production-ready code you’ll actually use! You'll get hands-on with the Launchpad, a framework-like repo for building AI workflows which is way easier to use than LangGraph, super flexible, and is equipped with a whole API/db/backend/devops infrastructure that is ready to go. And on top of that you're joining a community of developers (I also joined the Data Freelancer network), where beginners get mentorship, experts share feedback, and anyone can find collaborations, and stay up to date with the latest tech. State-of-the-art expertise, practical support, community: overall it's incredible value. For me, it really boosted my skills and my confidence as a developer!

Umberto Selva

AI Engineer

The GenAI Accelerator course was very positive and helped me better understand the possibilities AI can bring me professionally in the future. The content is well structured. The only thing that could be improved, in my opinion, is that the video switches between screens quite quickly, which can leave you feeling a bit lost. I had some difficulty getting the project up and running, but I finally got it done.

Diogo Lopes

Team Lead, Datip

I knew nothing about AI Engineering or working with LLMs. This really alleviated the getting started process by introducing you to the core concepts and teaching you how to use the technology from first principles. This is huge, as the course avoids the chasing trends and rather gives you the knowledge and tools to get started and navigate the ever-changing landscape of this technology. Getting access to the launchpad is also a huge value, especially for those who are doing freelance work in this space as it accelerates getting a project off the ground. If you're on the fence about joining and thinking that you could learn the information on your own through YouTube, you would be choosing a very difficult route. I'd highly recommend investing in this course - you won't be disappointed.

Jake McCall

Consultant, McCall Consulting

Before joining the GenAI Accelerator, my biggest challenge was bridging the gap between theoretical AI concepts and actually building robust, production-grade GenAI solutions. I had ideas but lacked the structure, methodologies, and real-world architectural insights to bring them to life. The GenAI Accelerator completely shifted my approach to AI engineering. Thanks to Dave’s methodical, hands-on guidance, I now feel equipped to professionally architect, design, build, test, and deploy any GenAI product I envision. He breaks down complex and rapidly evolving AI topics into actionable frameworks, with clarity and depth that’s hard to find elsewhere. Instead of chasing the latest frameworks, you'll learn how to think, evaluate, and execute like a GenAI engineer. If you’re on the fence about joining, here’s what I’d say: ✅ You’ll leave the program not only with stronger technical skills but with a complete shift in how you approach solving problems with AI. ✅ You’ll go from experimenting to executing. ✅ You’ll unlock the confidence to turn ambitious ideas into real, scalable products. This program is a catalyst for anyone serious about mastering AI engineering.

I was hammering my head all the way from Langchain to Llamaindex to Huggingface (even attempted smolagents to get a hold on subject ) , all the framework noise. Thankfully I found you, my progress has improved considerably sticking to LLM API's only. This video has again re-enforced my belief that SWE principals are indeed at the core of AI agent systems. Thank you Dave!

@abhishekmudgal604

Great and awesome course taught by Dave. Looking forward to implement the learnings in my day to day office work.

Amit

Lead/Director

The GenAI Accelerator course helped me systematize my knowledge of developing LLM-powered applications and understand what it takes to make them production-ready. Through this program, I gained valuable insights into the real-world challenges of implementing AI projects, along with practical methodologies and tools to address common obstacles. Most importantly, the course gave me the confidence to tackle AI development projects with a structured, professional approach.

Karol Boguniewicz

AI Solutions Architect

The GenAI Launchpad has been incredibly valuable in helping me build my GenAI applications. One of its biggest strengths is the ability to easily navigate the codebase and make targeted changes without getting lost in overly complex structures. The modular and clean architecture allows me to focus solely on the AI components, without having to reconfigure Docker, databases, or other backend elements each time I start a new project. What truly sets it apart is how it has accelerated my growth as a developer. By exploring the way concepts are applied and reviewing the provided examples, I was able to quickly deepen my understanding and enhance my skills.It’s also a great learning environment.

After becoming interested in AI and not having any experience with creating AI systems I started looking for courses that would expand my knowledge about this subject. In this course i got an inside look in how Dave & Datalumina develops these systems. After this course I now know the pieces of the puzzle required to run such a system, all while learning together in a community of developers. This course gives you a launchpad that solves complex problems so you can more easily start your own projects. I would highly recommend this course for anyone who wants to start to develop AI systems but doesn't know where to start.

Berthil van de Brake

BI developer, Insights in your data

The potential of AI is huge, and its application spans diverse use cases across almost every industry. However, this has led to a lot of noise and an influx of superficial tutorials and 'feel-good' projects powered by ChatGPT and similar coding generation tools, often promising to solve the biggest business problems. My biggest challenge was sifting through this overwhelming amount of information online, searching for tangible and repeatable strategies that could be applied to solve real business problems, rather than just 'feel-good' projects that rarely see the light of day. I’d been following Dave’s YouTube videos for some time and was impressed by how openly he shared his knowledge of building AI applications. I even put his tutorials to the test by building a WhatsApp AI assistant. Dave clearly distinguishes his lessons and experience from other influencers – focusing on "𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧-𝐫𝐞𝐚𝐝𝐲 𝐀𝐈 𝐚𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬." This has been my experience of the program. Having completed this hands-on program, I now feel equipped with the tools, mindset, and a supportive community to deliver powerful, production-ready solutions for my clients. To be successful, you need a combination of the right mindset and knowledge, the correct tools for the job, and a supportive community to seek help when you get stuck. All these attributes are part of the GenAI Accelerator program. If you're waiting for the right time, let me tell you something from experience: you’re unlikely to ever feel fully ready. Those who succeed don't wait; they take the leap, experience challenges, adjust their approach, and press on. This is why I joined the accelerator program and then went on to join the 12-month Data Freelance Mastermind group. The ingredients are there – Dave’s course is the recipe, and you need to orchestrate (be the chef) and bring it all together. What are you waiting for? See you in there!

Prior to this course, creating/integrating AI into a project was scatter shot, I just didn't have my pattern. Now I do. I went from "Pretty sure we can do that" to "I know how to do that". If you're on the fence, dive in - the value is vast and the lifetime access is no joke!

Marcus Swift

Founder & CEO, Clarity Business Solutions

I followed your advice to go pure python and OpenAI Agents SDK and that was the best thing I could've done to start with AI Agents Apps. When you start 'raw' without any framework in between, it really gives you full control and visibility of your application. Yes, it requires more lines on code, but with the amount to vibe coding tool options today, this is no longer an issue. I've built my first agentic RAG system app and it works really well. It is also pretty cheap to run as the models are getting cheaper every day. Thanks Dave!

Choosing from the vast amount of content online was challenging. Dave and his team have created a practical, well-structured course on the principles of building effective, scalable, production-ready AI systems. Thanks to this course, I was able to develop an MVP for a new product that gained initial traction and revenue. Moreover, the principles I learned now enable me to propose actionable AI solutions to my clients, boosting their business performance.

Ivan Dunskyi

Founder, Software Engineer

Before joining Data Freelancer, I was feeling isolated and unsure about the decisions I was making after leaving my job over a year ago. I lacked direction, clarity, and the confidence to navigate the independant consulting mode of working. I had no idea if I was pricing correctly, how to approach the right clients in the different geographies, or structuring proposals in a way that would land long-term, well paying work. Joining Data Freelancer has been a breather. Through the Q&A calls, resources, and support from the community (especially Dave, Hwei, and many others), being surrounded by like-minded people has given me a deep sense of belonging and motivation. I’ve learned how to build proposals with clarity, price and approach projects with true confidence. The mindset shift has been incredible — the confidence has brought about a personality change too. Beyond the career-focused help, I’ve even improved my lifestyle — sleeping better, staying healthier, and becoming more organised making better use of my time. My best results so far: - Landed a $3,000 paid discovery within 3–4 weeks of joining (at $50/hr). Received my first official client payment, which felt like a significant milestone. - Currently delivering a $9,000 proof-of-concept for a major pharmaceutical company, with promising signals for a long-term partnership. I’m truly grateful for this community — it’s been a life-changing experience. I’m excited about what lies ahead and hope to continue learning, growing, and contributing back.

I have been part of many Mastermind groups during the past decade. This is the only Mastermind group where its leaders are truly dedicated for the long-term. Whether you are a skilled freelancer in the data field or just beginning, this is the right group for you.

Leo Carlsson

Principal AI Consultant

As someone who started their programming journey later in their career, I find the launchpad to be the most empowering offering for AI Engineers of any skill level who are serious about their craft. The GenAI Launchpad let's me deliver projects faster, without forcing me to accept frameworks and abstractions that wouldn't pass the bar in rigorous business use-cases.

Ian Melchor

RevOps Systems Leader

The Launchpad is a game-changer for RAG projects. Instead of spending weeks setting up basic infrastructure like database connections, API integrations, and prompt engineering pipelines, Launchpad enables production-ready architecture right from the start. What I love most is that I don't have to rebuild everything after the proof-of-concept phase - the foundation is solid from day one. Highly recommended for anyone working on RAG or similar AI projects who wants to skip the tedious setup phase and get straight to building something meaningful.

Rok Popov Ledinski

AI Engineer & Applied Consultant

Currently just starting on my data freelancer experience. But straight out of the gate have been confronted with provocative questions that I never considered when thinking about starting a freelancing venture. I love being challenged, so this is perfect. I have high hopes for the things I will learn as I get more involved over the next weeks and months.

Great sense of a close-knit community with lots of experienced folks eager to teach. Direct access to Dave is especially awesome, with him sending you direct emails from Day 1 of joining. Personalized support from a personal coach is also very important for a program such as this. The program content itself is very comprehensive and filled with action items. It is not another course with just videos and you figure out everything on your own. Each week's content is accompanied bya progress check with your coach ensuring you've completed the action items.

Bex Tuychiev

It’s inspiring to be part of a program that genuinely values and invests in its members’ growth and success.

Youwei Zheng

AI Engineer and Data Analyst

Joining Data Freelancer was not an overnight decision; I have been thinking about leaving corporate and going independent for at least a year when I applied. Although the membership fee is not an insignificant amount of money, you will be under the direct tutelage of someone who has been in the grind for a decade and started with zero work experience. If Dave can do it, you can do it! If you would like to be your own boss but have no idea how to start, this mastermind program, along with the community members, the weekly Q&A meetings and the check-in calls with program managers, will set you on the right track. This is an opportunity to take charge of your own destiny and walk your own path. Why not take it?

Frederick Z

Even though I have a couple decades of experience, Datalumina has made my transition from employee to freelancer extremely simple. I was always daunted by the many legal and commercial formalities and obstacles, but by following their roadmap and methodology, I've accelerated my transition towards becoming a specialised AI Engineering freelancer. Also, Dave and the community in general is very welcoming, knowledgeable, and a great place to cross-pollinate with other people in the industry.

Francis Beeson

The weekly Q&A sessions and the community built since Data Freelancer's launch are filled with invaluable insights from other freelancers. You'll find people at all stages of their freelance journey. At the end of the day, it's up to you to put in the work, but you'll find all the necessary resources and support here to become a successful freelancer!

Vajk Turi

AI & ML Engineer

The program helped me get an assignment year contract within twenty days by structuring my business and services in the most organized manner possible. Even with three years of entrepreneurial experience, Dave has provided me with a fresh perspective on setting up services and business processes.

Sonny van Bergen

Joining Datalumina marked the beginning of an exceptional journey in learning and professional development for me. Under the expert guidance of Dave, I not only crafted a powerful personal and professional brand but also mastered leveraging the use of various platforms to aid in my growth as a data freelancer. The standout feature of Datalumina is its incredibly supportive community, rich in knowledge and conducive to growth for both novices and experts. Dave is one of the experts in the data and AI field and has built a program that is world-class!

I really enjoy learning at Datalumina Dave is an excellent coach. He focuses on building your personal brand and has a 30-day attack plan but also focuses on specific things like Upwork, Fiverr, LinkedIn, and YouTube. The community is incredibly supportive, has a wide range and depth of knowledge. All of this helps me stay accountable. Make sure you have some technical chops but it's an environment where beginners to seasoned professionals can grow.

Jd F

Dave is a true professional and my collaboration with him has been flawless. He took his time and spent 3 days with me and my team in Mamaia, Romania where he was a guest for 3 sessions of my podcast Waves of AI. He is one of the most competent people I know that has a real understanding of how AI works and how to integrate it quickly in your company.

Datalumina's Datafreelancer program helped me to become an independent freelancer! Being in industry for about 10 years! I always had this feeling for freelancing but I never took action because of the fear of not getting regular income but I overlooked my ability to earn morethan my regular income. Datalumina helped me to overcome that limiting belief and here I am writing this review! I can't recommend enough datafreelance program.

Vinay Prasad Devaraja

Before taking this course I had been trying to keep up with the fast changing AI engineering landscape and found it really hard to separate hype from content that was applicable to me. As a software engineer I wanted to learn how one might build applications with an engineer's perspective. This course offers that perspective. It is very hands-on and goes through a complete lifecycle of building an application from scratch all the way to a real deployment. There are tons of great tips from Dave and team, and useful tools along that way, and including a framework that they've developed that can be re-used to build other applications. I found this course very informative and I am far more knowledgeable today than when I started.

Ajit Nair

Software lead and architect

My number one challenge was underestimating how much I didn't know about AI systems and the vastly different approaches you can take when building them. Dave taught me practical methods that actually work and shared his own mistakes so I wouldn't repeat them. He's very honest and gives great advice, and also he provides so many extra resources to help us learn. The program completely changed how I will approach new AI projects. Instead of searching YouTube for hours to look for some guidance, he provides all the necessary resources right here in this course. If you're considering joining, just do it, it's completely worth it. You'll get real-world wisdom from someone who's been there and genuinely wants you to succeed.

Ella Kerrigan

Software Developer

The course was very well structured and had a good overview of the available content. The content itself was very good explained and we had step-by-step guidance on the project that we were building. The weekly catch up with the group was very helpful if you had some topics or issues you ran into and you had to discuss this with your peers and with Dave. Overall I can recommend this course if you want to know more off the AI scene.

Ivar Vinkenborg

GenAI Engineer, Evolyn.io

Before this program, I honestly didn't know where to start with AI Engineering projects. With so much constantly changing technology, I lacked a clear structure. From properly evaluating RAG systems and prompt engineering to the simpler things that others overlook, I was constantly overwhelmed by how to organize and use all that information appropriately. This program solved everything. It gave me a clear structure and showed me step-by-step, from A to Z, how to execute projects without leaving anything in the air. Not only that, but it provides amazing tools like the launchpad and all the libraries that are currently being used and tested in production environments today. What I loved most is that it's not theoretical—from day one, it showed real AI Engineer life: debugging errors, analyzing problems, and solving them hands-on with real-world tools. This program gave me the confidence I didn't have. Now I know all the ingredients needed to deliver top-tier AI Engineering projects, and I've practiced everything hands-on with production-grade tools. To anyone considering this program: it's more than an investment, it's a gift. We're getting tremendous value for the money. Thank you, Dave, for making complex AI Engineering concepts accessible and providing us with the actual tools used in production!

Andrés Espinosa Sanfiel

AI Engineer | Data Scientist

You nailed it with “overwhelmed”! It’s even an understatement. I find it almost hilarious that even the LLMs that I chat with are pretty much saying, you don’t need that, you’re already implementing that on your own 😅 I say “almost” because I’ve wasted so much time going, “oh what’s that!?” and it’s just another shiny thing 😂. Glad I found your channel. Thanks 👍

@CincyWong

Dave Ebbelaar is all you need. No, seriously. This man is the real deal. Thank you, Dave, for your generosity and insights.

@barspinoza

Before taking this course, my AI/ML workflow (if you can even call it that) was extremely fuzzy. It was barely an improvement over developing in Jupyter Notebooks, and I had no clear idea how to ship the finished product to production and offer it to clients. All that has now changed thanks to Dave, Joris and the lessons learned throughout the GenAI Accelerator. If you are like me before beginning this journey and have little clue as to how to bring your skills from inside your IDE out to the real world, get your lifetime access to your seat under the learning tree of people who do this professionally!

Frederick Zhang

AI Engineer, eXoteric Insights

Working with the Launchpad is very powerful. It is not easy to learn all the components. It takes some time and effort to study, but once you understand it and practice building some projects, you can build anything you can think of with AI. It gives you high-class education and an opportunity to develop a skill that is in very high demand right now.

Salvador Azuela

I intuitively booked this course based on Dave's excellent YouTube content. And I can only say that my expectations of this outstanding course were exceeded many times over. What Dave and Joris offer us here deserves my utmost respect. The way the course is structured, how they have integrated the ‘Gen AI Launchpad’ architecture framework and how they pass on their knowledge to us is unique in my opinion. The GenAI Launchpad provides an infrastructure for creating any type of AI application. The entire course, including the integration of this component, is a real game changer for me. During the course, you learn to think modularly, and at the end, you ultimately gain the tools and confidence to carry out customer projects in a more structured manner and in less time. It was the best decision of my life and I recommend this excellent course without reservation! For me, the value of the content offered here far exceeds the price, which is why this investment has more than paid off. I could list many more advantages here, but that would go beyond the scope of this review.

Michael Immink

Application Consultant SAP SEM/BW

Before joining the GenAI Accelerator, I struggled to find a solid, structured way to really learn AI engineering. Most courses or YouTube tutorials felt either too basic, scattered, or stuck in old-school data science. This program was a game-changer. It gave me a clear, deep understanding of AI engineering (the Datalumina way) and it delivered exactly what I was looking for. Super practical, super valuable. If you're on the fence: go for it. It’s the most complete, implementation-ready, hands-on program I’ve seen, and the skills I learned from this program gave me the confidence to say, “I’m an AI engineer.”

Hwei Geok Ng

Data Scientist

A huge thank you to Dave and the Datalumina team for delivering an outstanding course and enriching learning experience! Before joining GenAI Accelerator, my main challenge was confidently developing and deploying agent-based AI solutions in enterprise-grade production environments. This course has not only elevated my practical understanding but also empowered me to competently build robust agentic workflow solutions using Python with minimal reliance on third-party components, making deployment into cloud environments seamless and reliable. To anyone considering this course—don't hesitate! If you’re serious about advancing your skills in GenAI, this is the training you've been looking for.

Steve Atkinson

AI Architect

The Launchpad helped us through the entire process, from initial concept to production deployment. The product itself really streamlined our workflow and helped us hit our milestones. But honestly, what made the biggest difference was the support from their team. They were always available to help troubleshoot issues and point us in the right direction when we got stuck. The community around the product is solid too. It's been great connecting with other developers working on similar problems, and I've learned a lot from seeing how others approach things. Overall, really happy we chose this solution and glad to be part of the community.

Alessio Persichetti

If you’re serious about AI (even if you're just getting started) this program gives you the mindset, tools, and confidence to start building with purpose. I’ve been in software engineering for over 18 years and currently lead AI-focused initiatives as a Vice President and Lead Software Engineer at a major financial institution. Even with that experience, I found immense value in the structure, clarity, and practical depth this program offers. I’ve explored countless tutorials, blog posts, and frameworks—but nothing compares to the hands-on, end-to-end perspective this accelerator provides. You learn the why behind every architectural decision, not just the how. And the access to a real community of builders and experienced mentors is something you just can't get from a typical online course.

Nagadeep cs

Software Engineer

Very few courses actually cover the complete end-to-end AI engineering lifecycle, and this is definitely one of them. It's built around proven engineering principles and practices, with a focus on designing AI applications as robust, scalable systems—which is exactly what you need to deploy reliably in production.

Rok Popov Ledinski

Outstanding company fostering a global community of data freelancers, sparking innovation in data analytics and AI. Their commitment to collaboration and cutting-edge solutions sets them apart. Highly recommended!

Dave Ebbelaar is a developer who I have been following on YouTube for some time now, and he is one of the few who is thinking deeply and sharing his knowledge about how to design and build with GenAI in eminently practical ways. I'm very excited to see him consolidate this knowledge into a product called GenAI Launchpad. I believe this signals a shift of GenAI moving beyond the experimental into more focused problem-solving products and services.

Datalumina has been pivotal in my freelancing journey! Before joining Datalumina I was attempting to figure out freelancing on my own, but I didn't have a clear idea of how to go about it! For the last year I have been trying to transition my career to Data Science, without previous experience in tech I wasn't sure if I could even do freelancing without working for a big company first. It turns out that I can and I wouldn't have been able to do it without Data Lumina. Dave's expertise and experience as a freelancer are invaluable and the modules provide a clear guide on launching a freelance career! They cover everything from setting up your business to mindset, sales, how to land your first client and more! Even more important to me is the community, being part of a group of other highly skilled individuals has been indispensable! I've made new connections and have access to other expert advice! I'm three months into the program and have already landed three contracts, thanks to Dave, the Datalumina team and the community. I am able to confidently pursue my dream of freelancing knowing I am part of this community! I highly recommend Datalumina if you are serious about your freelance career it is well worth the investment!

This setup is going to save a ton of time and headaches for anyone building AI agent systems. It's like you've handled all the annoying infrastructure stuff so we can focus on the interesting bits.

Marcos Medeiros

AI Engineer

As a full-time Data Scientist, I had already started exploring the transition to running my own data consulting business, but I felt overwhelmed with ideas and unsure of which path to prioritize. Since joining Data Freelancer, the mastermind program and community have helped me align my focus, accelerating my initial progress. The program provides a wealth of information I wouldn’t have thought to seek out on my own, and the structured roadmap offers clear, actionable steps for preparing my business, even before branding myself. The branding section, in particular, has been incredibly useful in helping me develop a systematic approach to building a consistent brand scheme for my Ai consulting company, UnsupervisedBias. It’s also given me the tools I need to edit and maintain that brand as I continue to grow. I’ve found the sections on mental mindset and sales especially impactful. They continue to reshape my approach, making the shift from full-time work to entrepreneurship feel more attainable. Data Freelancer doesn’t just focus on technical skills—it takes a holistic view of what it takes to succeed in this space, which I’ve come to realize is essential. If you're serious about transitioning from a data-related position to running your own consulting firm, I highly recommend Data Freelancer for its ongoing community support and clear, actionable guidance.

Datalumina is great, I joined their Data Freelancer program. This program has been a game changer in regards to getting up and going with find freelance work AND how I think about running my practice. Since joining I have secured a contract to start, expanded my network of people whom are ACTUALLY building, and have a valuable resource to consistently improve my processes. If you are looking to get started "doing your own thing", or looking for a community to support you along the way, Datalumina will get you there!

Brandon Phillips

Since starting with Data Freelancer, I've gained a lot of skills that are needed in data freelancing. I just started freelancing and already got my first project. A big thank you to Dave, who taught me how to be seen online, get clients and everything else needed to do well as a data freelancer :) The program taught me both simple and complex stuff and gives me loads of tools to finish projects faster! I still have some lessons to finish, but I've already learned a ton!

Luuk Alleman

Founder, Everyman AI

The Data Freelancer Mastermind is the most helpful community that I have joined so far, and here's why: - Clarity: Dave has distilled his years of experience as a data freelancer into replicable strategies and templates. The materials taught in the Mastermind are not only executable but based on Dave's practical experience. He also includes knowledge from other experts to ensure we get the best results. I benefitted greatly, especially from the Upwork customer acquisition module, in which I obtained 4 responses out of 9 job bidding applications in 2 weeks' time. - Community: Everyone in the Mastermind group is always kind and ready to help. There are weekly meetings to check in with everyone, brainstorm solutions, and discuss the latest news in the industry. I love that we celebrate wins in the group! Seeing all our successes using the techniques taught in the Mastermind is a confidence boost that things work. Also, the meetings keep me accountable to stay on my goals. Thanks for supporting me through the hurdles of content creation and being confident in my skills. - Adaptability: The materials taught in the Mastermind are always updated. And through the weekly meetings, I learn from everyone about what's new in the fast-paced AI industry. That is a valuable thing for being in a group where everyone is sharing everything they know, and in turn, making each of us better equipped and better informed. Everyone in the Mastermind wants each other to succeed. I internalized the belief that it is impossible to fail in data freelancing with the support, the right strategies, and accountability from the group. It's a pleasure to be a part of it. Thanks Dave, thanks everyone!

I have had the pleasure of participating in the Data Freelancer program. I engaged in meaningful discussions with several attendees, exchanging ideas and insights with individuals from diverse tech and freelancing backgrounds. The program is insightful and delivered in a manner that is easy to understand yet intellectually stimulating. The Data Freelancer program is friendly, inclusive, and well-organized. There is a sense of community and openness that fosters learning and networking. It is easy for everyone to participate, ask questions, and share experiences, which is conducive to learning and networking. I highly recommend the Data Freelancer program to anyone looking to broaden their understanding of data-related projects while meeting like-minded individuals in the freelancing world. The Data Freelancer program's blend of professional insights and networking opportunities is invaluable.

Erik Samsoe

Hello friends! Today, I want to talk about something cool: a Data Freelancer Program led by Dave Ebbelaar. I joined this group when it was very small, just two members and Dave. Now, it's transformed into an amazing professional community with over ten members all collaborating and sharing insights! Our leader is like a skilled architect, but for knowledge. He has made a website that keeps growing with lots of information on freelancing. Dave is really open to change; he listens to our feedback carefully and adds it to the program in a smart way. Also, he includes his own experiences as he takes on bigger projects and grows as a freelancer. Another great thing is how seriously Dave takes the weekly meetings. He’s always on time, and he doesn’t just sit back – he's actively involved and brings new ideas to the table during these meetings. This shows how dedicated he is, by ensuring the group benefits from his insights and experience. And finally, let's not overlook the critical aspect - securing clients. I had the fortune of acquiring my first client through this program. Although it was a somewhat unconventional match, it harmonized well with my personality. Additionally, Dave is very generous and shares possible client leads with the group. It’s really about having the bravery to go for these opportunities. The program is a great place for growth, and Dave's help is a big boost in this process!

Anna Bansaghi

When i first joined Data Freelancer, i realized i'm probably the youngest person out there tbh haha. But obviously that's why its very exciting as well since most people that joins Data Freelancer are transitioning from a full-time job to Freelancing while i myself if from beeing a student to Freelancing and avoid that full-time job which i think is more pressure for me. After several months, it finally paid off and was really happy with the result. Obviously, it's still the begining and the next months will be even better obviously :). The Course content here is top-level, everything i need to get started and i do think that people that join even from 0 experience in freelancing could achieve greatness here. Recommended to anyone with true passion.

Daniel matias

Before I joined the GenAI Accelerator program, I had experimented quite a bit with AI tools and concepts, but I lacked the skills to build solid, real-world AI features myself. I understood software development from a product perspective and had a decent grasp of how things fit together, but I wasn’t yet confident in turning AI ideas into production-ready solutions. The program helped me close that gap. It was definitely challenging, especially without a strong programming background, but the lessons were so well designed and practical that I could keep up and keep growing. Everything was connected to real use cases, which made it incredibly motivating. Now I feel equipped to contribute meaningfully to the AI side of our application in a way that’s professional and sustainable. It’s not just about quick hacks anymore. I can think through architecture, design better prompts, and build features that are actually useful and reliable. If you’re motivated and have a real goal in mind, go for it. You don’t need to be a developer to succeed in this program, but you do need to be serious. For me, it’s been one of the most valuable learning experiences I’ve had.

Jedidja Speksnijder

EdTech Innovator, MaxAssist

I've been freelancing for 6+ years. I was on $50/hour for the last 3 years and struggling to level up. I even started a gig at $75/hour and got fired after a month... oops. I knew I needed some structure and support. And that's exactly what you get with Data Freelancer. After 2 months in the course, I'm now fully booked at $125/hour. I said I'd attribute anything over $100/hour earnings towards DF. So, I'm making an extra ~$4000 per month thanks to their support. For sure, one of the projects I'm doing, I would not have been able to do without DF's help (specifically the genai-launchpad which provides the much needed MLOps infra we can use for all projects). I'll be honest, I haven't done the video course. It's more geared towards beginners. But there are several more experienced guys in the group too and I know if I have more advanced level questions, they are welcome and answered. Dave is super helpful. The community isn't massive, so he really does have time to help you if you need/want it. I know if something goes terribly wrong on a project, I'll be able to get support. Having that safety net makes it much easier to reach for bigger projects, talk more confidently in sales calls and do cooler, more impactful work! Next stop $200/hour!

Adam Murphy

LLM Engineer

I am grateful to Dave Ebbelaar and Datalumina for the comprehensive direction and training delivered in the GenAI Accelerator course. The detailed level of instruction has been invaluable and has given me the confidence to begin designing and implementing AI solutions for a variety of finance and education use cases I have been planning for a while now.

Richard Odoom

Freelance consultant, Odoom & Co

The first 8 minutes of the video provide more value than all the LinkedIn posts i've read about AI throughout the year. Keep it up Dave and do not fall in the hype, this truly sets you apart. Amazing job 🙌🏻

@dani_fuya

Dave you are 100% spot on with every point. I spoke about the same building blocks recently as well. With all the noise in the space videos like yours are very valuable in keeping the field sane and focused on what really matters for production. I appreciate you taking the time to share this.

@IzzySolutions

The GenAI Launchpad has been a complete game changer for me. Not just in how quickly I can build high-value, production-grade AI systems, but in the confidence it gives me to move fast without fear of vendor lock-in. It’s clear this framework is built to evolve with the space, helping you stay aligned with best practices as things change. What stands out most is how battle-tested and simple it is. That combination has completely transformed the way I think about architecting AI systems. It removes so much friction and decision fatigue, letting me focus on solving real problems. Coming from a web development background, I now have a much more robust set of tools for AI-driven data processing and workflow automation. GenAI Launchpad didn’t just accelerate my build speed—it expanded what I thought was possible in my own work.

Mike

AI is full of hype, noise, and superficial tutorials—but few resources truly prepare you to build production-ready solutions. That’s where the GenAI Accelerator stood out. Dave’s practical, no-fluff approach helped me cut through the chaos and build real, scalable applications. This hands-on program gave me the mindset, tools, and support to confidently solve real business problems—not just play with prototypes. If you’re serious about AI, stop waiting. You won’t ever feel 100% ready. I’m glad I took the leap. (This is an honest review based on my experience—no sponsorship involved.)

Madhul Sachdeva

AI & Security Specialist

As a senior software engineer with three decades in the IT industry, I've seen many technology trends come and go. Before joining the GenAI Accelerator program, I was skeptical about whether AI could truly deliver value in real-world software development scenarios. The program completely changed my perspective. It demonstrated practical ways to integrate AI into existing workflows and showed me how to build solutions that actually solve customer problems, not just showcase technology. What impressed me most was learning to see past the buzz and focus on building reliable, production-ready AI systems. For anyone serious about understanding how AI can create real value for your organization and customers, I strongly recommend joining this program.

Jan Keijzer

Senior Software Engineer, Keijzer IT Solutions

The GenAI Accelerator took my skills to the next level by guiding me through a comprehensive, real-world AI engineering track, enabling me to design and build production-ready AI Agent applications and deploy them to the cloud for real-world impact.

Dirk S.

AI Engineer | Quant Methods Analyst, Uniper Global Commodities SE

Before joining the GenAI Accelerator, my greatest challenge was a significant mental hurdle to re-engage with the world of development. I knew AI was the future, but the thought of opening an IDE, analyzing code, and solving those inevitable configuration issues felt daunting and intimidating. This hesitation was holding me back from pursuing a path I was genuinely curious about. The deciding factor for me was Dave's no-nonsense approach, which I had already come to trust through his Skool community. The GenAI Accelerator delivered exactly on his promise of a digestible and complete learning experience. Through the expert guidance of both Dave and Joris, and the collaborative spirit of the other students, the complexity that once held me back was replaced with clear, practical steps. The hands-on projects and assignments didn't just teach me theory; they gave me the confidence to write code and solve problems myself. It was this transformation that turned a vague interest into a tangible and achievable goal. The program fundamentally shifted my perspective, showing me that a career in AI engineering was well within my reach. If you're on the fence about this investment, I would tell you to consider what you truly want to achieve. If you're looking for a program that cuts through the hype and equips you with the real, practical skills needed in the field, this is it. The direct, honest, and growth-focused teaching style of Dave is what makes the difference. For me, the GenAI Accelerator was the bridge from thinking "I should be able to do this" to knowing "I can do this and am making it my career."

Ilker Ertan

Integration Team DevOps engineer

I applied to Datalumina's GenAI accelerator as a non-programmer, but I was interested in expanding my hard skills to include AI engineering, so I gave it a try. For a non-coder, the program is very intense and on top of that you have to learn a lot of things individually as well as programming jargon to keep up with the class. I learned a complete systematic approach to designing and building LLM based AI systems. To be able to independently build a fully functional AI system, one needs to deeply study and understand all the different parts of the entire GenAI application ecosystem, and this is certainly not possible to master in 6 weeks for a non-programmer. I would estimate that it is more a matter of intensive study over several months. I will definitely continue my self study, especially of Python and all the components based on Datalumina's GenAI Launchpad framework. After GenAI Accelerator, I have even more motivation to become a full fledged AI engineer.

Marian

Workflow Automation Consultant

I struggled to start working on my own for two years. I lacked clarity and a simple, step-by-step process. Working alone, I constantly questioned myself and didn't take enough action. The Datalumina team helped me begin with confidence and support. They guided me and prevented me from making beginner mistakes. The course material is great, but the best part is talking one-on-one with someone who has been where you are. Wins? An easy one: on my first project I went from charging €50/hr to €150/hr. But the biggest win is having help in my darkest moments. When nothing seems to be working and you want to quit. Now, I know I have someone that won't let me quit. Thanks Dave, Hwei and all the community!

Building AI Automations for SMBs

Data Freelancer is the most practical, end-to-end program I’ve attended. It’s very much about the algorithmic approach for getting gigs and your name our there, but also about building a sustainable business with real systems, clear positioning, proven playbooks and focusing on long-term relationships with clients. Dave shares his blueprints that actually work in real world, not just theory. The community is sharp and supportive. If you want to move beyond the corporate grind and build real independence in data or AI, start here.

Rok Popov Ledinski

AI Engineer & Applied Consultant

I thoroughly enjoyed the community and being able to bounce ideas off of people in similar situations. The courses are in-depth and the mentors help you with anything and everything you need to get started in a professional capacity. I could not recommend the investment in yourself and your business more.

Alan Wade

Looking at the current state of agentic AI development and available resources (mostly wild experiments), I find this stack the closest to a real production-ready setup.

Zsolt Revay

It's been a pleasure talking with Datalumin personals. Very patient and informative. A good basis for personal development

noy oliel

The program covers all aspects of freelancing, from legal and sales, to tech tools and administrative setup. QA sessions and support from the community are also great! I would to have gone forward with freelancing without it!

Yorrick Jansen

Voice AI & Data Engineer

Everything has a proper structure, so it’s super easy to follow along. The action items ensure that we are on track, and the community is really supportive.

Luis Rendón

Data Freelancer sped up my decision making, causing me to jump into freelancing half a year quicker. I get to know all the necessities for starting up my company in the field of AI Engineering. Also the Q&A's are really helpful, with people helping each other on several topics. I get access to helpful project examples to get started.

A little over a year ago I was floundering in my corporate job, wanting to take advantage of the opportunities in Generative AI but lacked the support and knowhow to focus on this goal. I decided to invest in the Data Freelancer program and immediately began to gain focus on where to put my efforts. I have launched my own AI Sales Prospecting tool and have generated considerable revenue. I couldn't have done it without the support of Dave and the amazing group of people in the Data Freelancer program.

I am following the Data Freelancer program and I can recommend it to anyone who wants to become a freelancer in the field of Data and AI but doesn´t know where to start. The program is very comprehensive and talks about all the important aspects: from administration / tax aspects, how much you can charge, how do you keep yourself motivated, how do you find clients and how to deliver the projects. It also allows you to become part of a very active community of people who want to achieve the same goals as you.

Laurent

Besides the very thoughtful and complete material I really like the network of people that you can tap into. Its a nice way to stay on top of the industry get support and connect with likeminded people around the globe. Great bonus is the constant addition of new valuable content.

Julian Kaiser

AI Engineer

After joining Datalumina, I am a reformed person. It does not just help you build a freelancing journey but also makes you think and act in many positive ways. The community Dave has built is amazing and helps you on each step of your freelancing journey.

Prachi Kulkarni

I have been part of the Data Freelancer community for 6 months now. Besides the knowledge being shared in the course, it's the community aspect that is highly valuable. Being able to share and learn from the journey of others on the same path is immensely motivating.

Nguyen Hai Anh

Everything in the program is great. All you need to start a freelance business is here, from setting up a proper mindset for success to the technical stuff like registering your business and getting gigs. I especially like how it is tailored to the Data and AI field, which you can't find anywhere else. And finally, there's always someone there to help get you unstuck when needed.

Ravi Rai

My first and strongest impression is that Data Freelancer is an incredibly empowering program. I've been trying to start my freelance business for a while, but I lacked clear direction and support. Now, I feel I have inspiring people to learn from, an initial path to follow, and the confidence to find my own way. The team is amazing, and the community is both supportive and welcoming. All the good stuff is inside this program!

Nicola Battoia

Building AI Automations for SMBs

I'm part of the Data Freelancer program from DataLumina and the experience has been amazing. It is a complete business guideline on how to start your freelancing business, do marketing, sales, inbound, outbound, service delivery etc. Also Dave is part of almost 100% of the conversations in the Skool community.

Darko Kolev

This Mastermind was the most comprehensive I've ever experienced! It got straight to the point, grounding each concept solidly and providing practical tools for implementing them into your freelancer journey. The support and clear, structured plan for building a successful career as an AI and Data Science freelancer are truly invaluable. Data Freelancer has truly been a transformative influence in my life. The community and team are awesome!!

Mariano Chicatun

I am really impressed. This would enable me to start my projects muuch faster. Following the quick startup guide, I was up and running in a couple of minutes, which is really cool. Impressive that you also thought of production deployment. The project structure adheres to very familiar principles, so it is straightforward to navigate through.

Rok Popov Ledinski

AI Engineer & Applied Consultant

Before encountering Data Freelancer, I already had extensive experience around consulting and business. And I was already an accomplished Cloud Data and AI Architect. Participating in this program has made me so much better! All the materials are professional, high quality, and directly useful. Even better is the engaged community ready to provide expert advice and help. It's a force multiplier. I'm very pleased with the program and grateful to Dave and the Data Lumina team for putting it together.

I have been part of the Data Freelancer program by Datalumina for nine months, and I must say, it has exceeded my expectations in every regard. The courses are incredibly clear and offer a variety of approaches, making it easy to follow and implement. The weekly Zoom sessions are a highlight for me, where Dave and the members provide insightful and friendly support. These sessions are not only educational but also a great platform to discuss the latest AI/ML technologies and implementations and learn from real experiences shared by peers. Seeing other members succeed in real-time has been incredibly empowering, giving me the confidence that I too can achieve similar success. Watching Dave's business grow up close has been truly inspiring. His dedication to sharing his tried and tested methods through the program is a testament to his commitment. I even tried one of his strategies in the Japanese market, and it's paid off immensely, resulting in financial returns that far exceed the cost of the course. Having participated in several other courses, I can confidently say that Datalumina's program is outstanding. The combination of video courses, a thriving community, and a high success rate among participants sets it apart. Plus, the fact that Dave actively practices what he preaches adds a layer of authenticity and trust. I highly recommend the Data Freelancer program to anyone serious about succeeding in the data freelancing world!

A couple of months ago I received a tip to join the Data Freelancer community and follow the program. This was a golden tip; Daves courses in the program are great and gave me enough best practices, formats and assignments along with nice theory. I learned to handle the most important parts of true freelancing which in my opinion are customers, the marketing and sales to find customers and excellent delivery of services. And when I started to actually put it all into practice, I had an ROI within 4 weeks! I most definitely recommend Data Freelancer to you if you're into freelancing anything data related.

The transparency that Dave provides when explaining the freelancing process is unmatched. I loved how he dived into everything from client acquisition to the finance side of things. Additionally, the two hour weekly Q&A call is an amazing feature of the program. It allows you to pick Dave's brain on anything from up and coming tech, to specific questions about starting your freelancing business. Overall, the program has been great and I highly recommend it to anyone who has been interested in setting up a freelance business.
