Barcelona | Claude Build Day
Join a Claude Community Event — Barcelona's Claude Build Day, part of Claude Community House.
⚠️ Limited spots — only register if you can definitely attend ⚠️
We have 50 spots and registration is subject to host approval. If you RSVP and don't show, you lose priority for future events. Community over flakiness.
What is this?
No talks, no panels, no pitches — just laptops open, building AI projects side by side. Claude Build Day is where founders, makers, and AI builders come together to ship real things with Claude Code.
This session is one full day of the Claude Community House: one week in September where ambassadors from 14 European cities move into the same building in Barcelona.
How it works:
09:00 — Doors open, coffee, set up your workspace
09:00–16:00 — Deep work time on your projects, with ambassadors on hand when you're stuck
16:00–17:00 — Present what you built
All day — the House lobby stays open for coworking, so drop in and out as you like
17:00 onward — The AI Afterwork takes over upstairs (separate ticket, run by The Tech Nation)
Who should come?
Anyone building with AI — first-time founders, serial entrepreneurs, side-project hackers, or curious makers. All skill levels welcome. Bring your laptop and whatever you're working on.
The vibe:
Think co-working meets accountability group. English-speaking. Laptops open. Help available when you're stuck.
Rules:
RSVP = show up (no-shows lose future priority)
Ship, don't pitch
Share knowledge openly
Help others when they're stuck
Where:
B@B - Bilbao 128, Poblenou, Barcelona — the building hosting the whole Claude Community House from 21–24 September.
About Claude Community House:
Barcelona already has a Claude community that meets and builds all year. For one week, ambassadors from 14 other European cities bring their own version of that into the same building — and this Build Day is one of the sessions during that week. Claude Community House is an independent community initiative, co-produced by The Tech Nation, Happy Operators and clauders.com with the European Claude Ambassadors network. Not an official Anthropic event.
