Where it comes from
Why it is called a house
Barcelona already has a Claude community. It meets, it builds, it argues about context windows over beers on a rooftop, and it has been doing that all year. The Claude Community House is what happens when the other European chapters bring their own version of that to the same building for a week, under one name.
The whole thing is hosted and animated by the ambassadors, which means the person giving the talk is the same person you will be debugging with an hour later. Run as a community initiative, and co-produced by The Tech Nation, Happy Operators and clauders.com.
