ACT Berlin #4 (AI Coworking Tuesday)

ACT Berlin #04 (AI Coworking Tuesday)
A working day for people building with AI in Berlin.
Bring your laptop. 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
12:30 — Lunch break together
13:15 — Workshop/Talk by Soulrouter
18:00 — Wrap
Solrouter: Build With Private AI
Every prompt you send to AI is indexed by Big Tech, stored in a centralized database and used for model training. Fine for a weekend project. Not fine for anything touching health, finance, legal, or proprietary code.
// WHAT WE'LL COVER
Why private AI — the threat model nobody puts on the slide, and who actually can't ship without it
The stack — how the cryptographic privacy guarantees work
Use cases — what people build once the data-exposure constraint comes off
Build with us — the SDK, a funded key, and how to ship a working private-AI integration by the end of the session
// 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.
Apply to join. We curate the room. Tell us what you're building so we know you fit.
