Data Scientist
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, GenAI Launchpad, and Dave's direct support gave me confidence to tackle bigger projects I couldn't have done alone.

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.

Data Analyst
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 landed a $3,000 paid discovery within 3–4 weeks of joining and received my first official client payment, which felt like a significant milestone. I am currently delivering a $9,000 proof-of-concept for a major pharmaceutical company, with promising signals for a long-term partnership.

You have technical skills - maybe you code, maybe you analyze data, maybe you're just getting started. The specifics don't matter. What matters is you see what's happening: AI is the biggest career opportunity of our lifetime, and you want in.
You're tired of being undervalued for the problems you solve. Tired of meetings that could've been emails. Tired of maintaining systems when you could be building the future. You know there's more to your career than debugging someone else's technical debt.
The best part? You can start this journey without risking your current job security. You don't need to be a marketing guru or sales expert to make this happen. Your technical expertise is the foundation, and we'll teach you everything else.
