ACT Berlin #13 (AI Coworking Tuesday)
A working day for people building with AI in Berlin.
Bring your laptop (& monitor cable). Ship something. Talk to people who get it.
// THE RULES
We keep it high-signal. No sales pitches. This is a space for those who actually build and deploy.
// THE FORMAT
Deep Work: Focus on your own projects in a curated environment.
Expert Deep-Dive: One high-level technical session per event to level up your stack.
Curated Networking: Connect with like-minded peers over lunch.
// VIBE-CODED MATCHMAKING
To ensure the highest quality of connections, we’re premiering our vibe-coded matchmaking app. No more awkward small talk, get matched with the exact people who can help you ship faster.
The day
09:30 — Doors open, coworking starts

Fixing Cognitive Debt: how to stay in the driver's seat with your coding agent
18:00 — Wrap
// WHAT WE'LL COVER
Vibe coding works, until it doesn't.
Agents ship thousands of lines a day. Reviewing all of it doesn't scale, so you end up with a modern LGTM (hope it doesn't break) and a product you have to reverse-engineer yourself.
This session covers how to keep control:
Old school: commit to an architecture, decompose properly, lock decisions in with tests
New school: give your agent a source of truth so it stops rediscovering your product, split product design from implementation, log decisions, capture workflows as skills, make the agent prove it hit the goal
Ship in vertical slices, not one-shot prompts. 80% of the work is figuring out what to build.
// WHO IT'S FOR
Founders, engineers, and researchers shipping AI where data exposure is a real cost and anyone who's ever hesitated before pasting sensitive context into their chat interface.
Hosted at w3.hub, 3rd Floor.
