What this is
Build x AI is a community for people who build things with AI. We meet in person in Berlin-Kreuzberg, show each other how we actually work, and connect the people building similar things. No keynotes, no sales pitches: real setups, questions all the way through, and drinks afterwards.
Run by Ape Unit, a Berlin software company since 2010.
Our evenings
Different evenings for different needs.
Pick the one that fits, or come to all of them.
01
Introduction to AI Agents
For people new to agents. What an agent actually is, explained and then shown live with Claude Code and Codex. No coding needed. Bring your questions.
02
Show & Connect
People show what they're building, and we connect the people working on similar things. Bring a project, or just come to meet people.
03
Builders' Exchange
For people who build with agents every day. The room votes on the topics (evals, multi-agent setups, harnesses), then we compare real workflows, real setups and real failures.
Every evening
When you check in, a short card about you appears in our community chat: what you're building, your tools, your level. So people know who to talk to.
