about this event
Most hackathons end at the demo. We built this differently.
The Brderless Buildathon is a two-part format: a curated 24-hour build in New York, then two weeks to keep shipping, then a Demo Day where the selected winning teams show a real product.
Part 1 - The Buildathon (October 4)
100 vetted builders. One theme: AI agents that do real work - planning, tool use, multi-step execution, human-in-the-loop. Not chatbots.
The day:
10:00am: Doors open, breakfast
11:00am: Keynote from speakers & team formation
12:00pm: Lunch & build
3:00pm: Project check-ins
4:00pm: Submissions close & final selections
5:00pm: Judging round one, awards, and selection of the teams advancing to Part 2
Food and caffeine for the full 24. Top teams advance to part 2.
Part 2 - Demo Day (October 8)
Selected teams get two weeks and mentor support + credits to turn the weekend into a product. Then they demo live to a curated room of investors, operators, and sponsors - 7-min demo, 5-min Q&A.
Who should apply?
Engineers, technical founders, AI/agents engineers, and product people who ship. Solo, with a team, or matched with one - all fine. If you come as a pair or group, please make sure that everyone registers.
