AI Builders × commIT | Hack Day Berlin 2026

A one-day AI hackathon from AI Builders Club with commIT, hosted at ImmoScout24 in Berlin. Bring an idea or come alone: the morning runs idea pitches and team matching, then teams of up to four build through the day. Three tracks: go-to-market AI (lead research, outreach, sales agents, monetisation), an agentic-AI track built on Nebius Token Factory, and an open track. Doors 09:45, challenges 10:00, feature freeze 15:30, live demos 16:00, judging and awards from 17:00, then pizza, drinks and networking until 22:00. Local hosts are Martin Kaiser, Lingkesh Vijayakumar, Andrei Marcut, Simon Schreiner and Vitalina Alipova. Tickets are 16 euros standard, 10 for the first 42 commIT members and 5 for students, which the organisers approve one by one. A waitlist opens once it fills. Why go: a full build day with a deadline and a live demo at the end, not a panel about AI. Best for engineers, product people and founders who want a working prototype by the evening.
