VibeCoding Sprint: Build Your Startup in 3 days (Official partner: Lovable)
Details
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. The sprint will start on the the 03, Dec 2025 10:00 am with opening for the teams and will finish 05 Dec, 2025 at 18:00. From 18:00 to 21:00 teams will be pitching their products to the mentors and guests, they will receive feedback and one team will be granted the first place prize.
