Freelance | 8–20 hrs/week | Remote (EU/UK)

Are you a seasoned venture builder with an entrepreneurial mindset who can spot business opportunities, identify blind spots, and understands the intricacies of building ventures from the ground up? Do you have 8 to 20 hours per week to contribute alongside your primary projects or commitments? Join us in shaping how AI learns from and applies authentic venture-building expertise at scale.

About The Role

10x.team connects expert freelancers with leading AI labs building next-generation models. We are seeking experienced venture builders based in the EU or UK to help enhance the depth, realism, and applicability of AI-powered business and venture creation systems.

What You Will Do

* Review and refine AI-generated outputs covering topics such as venture creation, business validation, go-to-market strategies, fundraising, and scaling startups

* Evaluate AI content for business realism, practical soundness, and relevance to real-world venture building

* Draft realistic scenarios and case studies reflecting your experience launching or developing new ventures

* Identify gaps, flawed assumptions, or impractical logic in AI-generated responses

* Create alternative perspectives from various stakeholders (e.g. founder, investor, operator, or advisor)

In Simple Terms

You will assess and improve AI-generated content to ensure it demonstrates real venture-building practices and a nuanced understanding of entrepreneurship. Rather than delivering traditional consulting work, you’ll apply your hands-on experience to help AI systems truly understand the complexities and realities of launching and building ventures.

Who You Are

* An experienced venture builder, startup founder, operator, or advisor with significant hands-on experience

* Based in and eligible to work in the EU or UK

* Skilled in early-stage venture development, validation, go-to-market planning, fundraising, or growth

* Able to spot weak logic, impractical pathways, or unrealistic business plans

* Familiar with the frameworks, processes, and best practices of venture building

* Comfortable working independently and providing clear, actionable feedback

* Available for 8–20 hours per week, with near-term start

Why Join?

* Flexible, fully remote work that fits your schedule

* Apply your venture-building expertise in a cutting-edge AI context

* Directly contribute to improving the next generation of AI systems

* Access clear project briefs and supportive onboarding

* Opportunity for long-term collaboration based on performance

* A short written evaluation
