The week, narrated.

Monday, the twenty first of September. The Claude Community House opened its doors at Bilbao one two eight, and fifteen ambassadors from ten European cities moved into the same building.

It started with coffee. Claude and Coffee ran three hours, laptops open, nobody quite sure yet who anyone was.

Then the Clinic. Jérémie and Manar took twenty seats and a room full of stuck projects. Julia Hernandez, Applied AI at Anthropic, sat in as a guest. You could bring the thing that was not working and ask the people who build the tool why.

The middle of the day went hands on in three directions at once. Florian Steiner showed how to stop Claude forgetting your company, using a folder of linked markdown files instead of a vector database. Make ran a two hour build where you wired Claude to external tools through MCP and put human approval around the whole thing. And a room of small business owners built an agent that reads their own company files.

Upstairs, a table of people learned to crochet a Claude crab. Two hours to be bad at something on purpose.

At two, Stefano Amorelli from Qonto walked through building the first MCP for business banking in Europe. Security, regulation, zero to production.

At three, Julia Hernandez came back for an hour on what separates people who get real leverage out of Claude Code from people who use it as a faster autocomplete.

Then the afternoon turned philosophical. Claude Conversation put ten tables of five in a room. Philosophers, teachers, journalists, founders. No demos, no pitches. Every table left with one problem written down, to be built on Thursday.

At five, Filip K ran the first Disconnect hour. No laptop, no phone. Breathing and body work, to land in Barcelona and in the week.

At six the building emptied and everyone ended up on the roof. DJ Papa, wine and cava, four hundred square metres of terrace and the Poblenou skyline going pink.

Night one of four. Nobody knew anyone for about twenty minutes.

Tuesday, the twenty second of September. Day two, and the House had settled.

The Clinic ran again at ten. Same deal. Bring the project that is stuck, leave with it moving.

Next door, Stitch Club. Three hours, a needle, some thread and a Claude pattern. You could stitch the Gaudí Claude or design your own on the House website, where every pixel is one stitch. No laptop in the room.

After lunch, Manar and Nico opened up five skills they actually run. Not prompts. Folders that Claude reads by itself, with the instructions, the examples and the files it needs. A skill turns something you re-explain every week into something you invoke once.

At two, a room of small business owners got thirty minutes of Claude Cowork, the version built for handing over real jobs rather than chatting. Sorting the inbox. Drafting the proposal. Then two hours of building.

At four, Selim Boudis told the story most conferences skip. He is not a coder. He went from AI curiosity to agentic workflows he actually uses at KOLABS and Kairros. What worked, and what did not.

Also at four, Lumoo built a fashion campaign live. A flat garment in, an on model shot out. No studio, no samples, no shoot. They showed the real latency uncut, and the part everyone else edits out, which is where it breaks.

At half four, Jamie Gulcan ran Disconnect. An hour to slow down, play a little, and meet the people around you rather than their job titles.

At five, Softr. Francisco Opazo hosted, with Mariam Hakobyan, co-founder and chief executive, in the room. Two hours connecting Claude to Softr, describing the app you actually need, watching it get built, then taking it apart.

At six, the roof again. Night two was Ambassadors night. The fifteen people who run the Claude communities across Europe hosted, and only they wore the Gaudí top hat. State of Mind on the decks.

The instruction was simple. Find them in the crowd.

Wednesday, the twenty third of September. Build Day.

From nine in the morning, fifty people sat down with laptops open and built AI projects side by side. No talks, no panels, no pitches. It ran until five.

Around it, the busiest day of the week. Fifteen sessions.

At ten, Javier Rayón from Sesame HR and Gianluca Rosania from Workfully took a room from a blank page to a working HR workflow. A recruiting pipeline, an onboarding process, a career site.

At eleven, Katrin took people with no technical background from an idea to a website they could actually share.

At half twelve, Javi Gascón interviewed Typeform and Qonto on how two of Europe's best known scale ups really use Claude inside the company. Qonto serves six hundred thousand small businesses across eight countries and shipped its own MCP in June.

At one, a room of fifteen communications people worked on the things they have to ship. Press releases, briefing notes, statements that have to land right the first time.

At three, Joaquim Cardona explained how he cut support enquiries at JSON2Video by ninety five percent and made the customer experience better at the same time.

Also at three, Florian Steiner walked through the four Claude certifications and a realistic study plan. And Geoffrey Rolin Jacquemyns argued that sociability is the last human moat, and that it can be engineered rather than inherited.

At four, three things at once. A clinic on turning your contacts into a system you can actually search. Two hours building an AI second brain inside Claude Code. And the Stripe Community session, a short talk then a hands on hackathon on simplifying your tech stack with AI.

At half four, Jamie Gulcan ran Disconnect again. Mid week, the day you stop networking and start talking.

At five, Alicia Larrazabal showed Radar Venezuela, a tool built in the middle of the Venezuelan earthquake. And Make went deep on orchestration, and what happens when one agent is not enough.

At six, the roof. Night three, open floor, no agenda, and the Build Day teams coming straight up with something that almost works. SAÈZ on the decks.

Thursday, the twenty fourth of September. The last day, and the one the whole week was pointing at.

On Monday, Claude Conversation put ten tables of five in a room. Philosophers, teachers, journalists, founders, people from institutions. No demos, no tools, no pitches. Every table left with one problem written down.

On Thursday, the House builds answers to them. The Claude Impact Lab runs nine to six and closes the week, on the day of la Mercè, when the rest of Barcelona is off.

Around it, four more sessions.

At ten, Lumoo runs the fashion studio again. One hour, one campaign, built in front of you. Flat garment in, campaign out.

At eleven, ily frills runs a video workshop. Two hours with fifteen creatives, bringing different AI tools together to turn a story into a finished video. Bring a laptop and a live piece of work.

At two, Bradley Lauretti runs Claude for Musicians. No music gets made in this session. It is about the other job. Ten years of tour history in a Drive folder you have never opened, an album coming out, and you are also the social media manager, the booking agent and the merch department.

At four, Kris Talova from Lyra AI goes physical. Automating when the air conditioning comes on. Watering the plants. Building your own reader. The point being that hardware just became accessible to people who are not engineers.

At six, the roof for the last time. Closing night, on la Mercè. The city is off, the House wraps up with the Impact Lab, and the roof gets the last word. Selen Us on the decks.

Four nights, four DJs, the same terrace. Then everyone goes home to London, Paris, Milan, Munich, Nuremberg, Madrid, Tallinn, Budapest, Amsterdam and Stockholm, and starts organising things in their own cities again.
