WTC Buildathon

AI Builders' two-day buildathon at the World Trade Center on Strawinskylaan: challenge briefing and one-minute pitches, team matching over a sponsored lunch, then build time with a vibecoding workshop at 14:00 and a hardware workshop at 15:00, dinner, an overnight hack session, and demos and judging from 16:00 on the second day. Doors 10:45. Run by AI Builders Club, the volunteer community behind more than a hundred meetups and hackathons a year across Amsterdam, Berlin, London, Lisbon, Rotterdam and Miami. 10 euro, 5 euro for students - a contribution that covers venue and food rather than a ticket price.

Why go: two days with hardware on the table and overnight build time is a different thing from an evening hackathon, and teams form in the room rather than beforehand. Expects you to be comfortable with LLMs, RAG and agents.
