/ About this event
Most hackathons end with a demo to judges who've never touched your product. This one ends with real users/ICP telling you what they actually think, while you still have time to fix it.
THE DEAL 20 teams. All technical builders. One vertical. 12 hours to build a feature that matters. $10K+ in prizes. Million of Credits.
THE TWIST You're not just building blind and hoping. With Sense AI, every team gets matched to real ICP testers to user test while they're building in minutes. Ship something, get it in front of the people it's actually for, hear what they say, iterate. Repeat. It just makes Sense.
ALONG THE WAY 1:1 office hours with a16z speedrun and YC founders on what it actually means to build human-centered products and what most teams get wrong.
