AI Builders Berlin — October

The Berlin edition of AI Builders Club's monthly meetup, at Aethos in CIC Berlin. The format is short demos rather than long keynotes, with most of the evening left for talking to people. Nicolai Bohn opens on test-driven development for AI agents and who writes the tests. Gesa Schneider follows on what happens when AI memory changes what you shared, and Mykola Penkovskyi of Fin argues against letting your agent make you stupid. Doors 17:30, pizza 18:30, talks from 18:45, drinks and networking from 20:10, close 21:00. Paid: a flexible ticket from 7 to 14 euro on Luma, with sponsored tickets on request. The waitlist is open. The organisers ask that you arrive with basic LLM concepts already in hand, and sessions are streamed and recorded. Why go: Berlin has no shortage of AI panels and few rooms where people demo what they actually shipped this month. Best for engineers and founders building with agents.
