After struggling at $50/hour for 3 years as a 6+ year freelancer, Data Freelancer helped me reach $125/hour in just 2 months – an extra $4000/month. The structure and Dave's direct support gave me confidence to tackle bigger projects.

Two years into freelancing, I'm on track to earn 7-8x my Amazon salary and have hired three engineers. There will be no better investment of your time, your money, and your learning bandwidth than being inside a community like this.

Data Freelancer gave me the confidence and clarity to bet on myself. I got my first client at $13K, converted my full-time role to consulting, and crossed $100K in revenue 3 months ahead of my original goal.

As the program progressed, it became clear that the freelance path suited me best for the coming years. Since joining, I've landed my first two AI freelance projects, which was a big milestone and proof that the system works.

I had no idea how to earn a living selling my skills, even after years in corporate as a principal engineer and director. The program gave me the confidence and insight I needed to land my first client.

This program has been a game changer in getting started with freelance work and changing how I think about running my practice. Since joining, I secured a contract, expanded my network of people actually building, and found a resource to consistently improve my processes.

As a full-time Data Scientist, I was exploring the transition to running my own data consulting business but felt overwhelmed with ideas. Data Freelancer helped me align my focus, accelerate my initial progress, and make the shift to entrepreneurship feel more attainable.

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.

Data Freelancer gave me the structure and guidance I needed to turn my skills into a consistent freelance business. I landed my first contract worth just under five figures much sooner than expected, and within the first 6 months of freelancing I was able to quit my job.

This is the best course I've ever enrolled in! Dave helped me become an independent freelancer. I had the desire to start freelancing but was afraid of losing a stable income. What I didn't realize was that I could earn more than in my regular job.

Dave Ebbelaar speaking on stage

The math has changed

The market today doesn't reward what it used to. Layoffs hit every level, internal raises cap at single digits, and companies are restructuring their engineering teams. At the same time, AI gives a single engineer the leverage that used to take a small team.

If you can already ship real software, the highest-leverage move isn't waiting for the next promotion. It's building a second income on top of your day job. Real project work in evenings and weekends, charged at market rates and proven on your own terms. The risk profile is completely different than it was two years ago, and windows like this don't stay open.

Curriculum

Everything you need to launch a freelance career

Pick the right freelance model

Map your skills, goals, and lifestyle to the freelance model that fits, from project-based contracts to retainers and productized services.

Set the right foundations

Register the business, set rates, structure your offer, and put the operational pieces in place so you look like a pro from day one.

Think like an operator

Shift from employee to entrepreneur with the mental models, frameworks, and decision-making patterns that separate freelancers who scale from ones who stall.

Become the obvious choice

Turn the experience you already have into a clear signal of expertise. When serious clients are looking for help, you're the one they reach out to first.

A portfolio that converts

Build a high-converting portfolio that opens doors even if you don't have past freelance projects to show. Use what you already have.

Close 5-figure deals

Craft proposals clients can't ignore, run discovery calls that price you up instead of down, and close serious projects with confidence.

Systemize client acquisition

Build a repeatable pipeline so you never run out of clients again. Works even if you hate the word "selling."

Protect your business legally

Contract templates, IP terms, and payment safeguards that save thousands in legal fees and keep difficult clients from costing you.

Snowball your pipeline

Extend contracts, turn one client into three through referrals, and compound your pipeline over time so each project is easier to land than the last.
