A fast-paced 3-day sprint where founders use AI VibeCoding tools to turn an idea into a real startup. Co-hosted with PUZL CowOrKing and proudly supported by our exclusive VibeCoding partner, Lovable. Build, refine, and pitch your prototype on Friday evening. Suitable for solo founders and teams, no technical background needed.

Founder Institute, together with our co-host PUZL CowOrKing, invites you to the VibeCoding Sprint – a 72-hour challenge where founders turn an idea into a working startup prototype using AI-powered VibeCoding tools. This edition of the Sprint is proudly supported by **Lovable, our exclusive VibeCoding partner**, whose platform will play a central role in helping participants build faster and more efficiently.

No technical background is required. Participants follow the Rule of One (one problem, one customer, one solution) and work with focus toward a demo-ready prototype by Friday evening.

If you want to join as a **team of builders**, please fill out the application form below.
If you prefer to attend only the **Demo Day** and watch the pitches, please register solely for the event.
