Claude Community House · Barcelona · 21 to 24 September 2026
What makes a community event work, and a community in general, is the people who take part in it. Even more, the people who take an active part.
If you are reading this, you took part, one way or another. You ran the rooms and shared your expertise. You gave your week as a volunteer and sweated with us. You backed us, lent us your spaces, your services, or any one of your many talents.
We won’t get too sentimental. But if everyone left the Claude Community House at the end of the week with a little pinch in the heart, it’s because every single person involved gave their best to make it memorable.
So, sincerely: thank you.
Fernanda, Matt, Olivier and Jérémie

Claude Community House · Barcelona · 21 to 24 September 2026
A whole building in Poblenou, 42 sessions, 16 Claude ambassadors and the people who build with Claude every day. Deep technical content, and a community where engineers, founders, public institutions and first-time users learned in the same rooms.
An independent community event, organized by Jérémie Benhamou, Matt Roberts, Fernanda Grace Lins and Olivier Legris with the Claude ambassadors, supported by Anthropic. Free for everyone.

Three moments from the week
Teams took real challenges from the city and built with Claude all day. The runner-up, Saviesa, lets elderly people teach what they know, by voice, through the social centres they already go to.
As told by team member Natalia Campanella
Tables of five, no laptops. Someone from Catalonia's digital administration, thinking about AI for a public workforce of over 200,000, sat next to a 19-year-old teaching himself to build.
As told by participant Swenja Paul
The Wi-Fi died mid-session. Two hours later, people were still sitting on the floor so they wouldn't miss a word.
As told by participant Boryana ChervilovaThis was not a meetup with slides. Anthropic’s Applied AI team opened the week with a Claude Code masterclass to a standing-room auditorium. Scale-ups showed their internal playbooks. Ambassadors brought the setups they use every day, and the rooms were full from the first hour to the last.
How to become a power Claude Code userJulia Hernández, Applied AI at Anthropic. People standing along the walls, hands up for every question.
From the people who build the tools we work with, to those who use them in the most unexpected or specialised fields, and those who guide teams through the AI shift every day: every talk was on point, and every one of them was worth the room.
“I was impressed by the quality of both presenters and attendees”
“Grateful to everyone at Claude Community House for putting together a day this dense with substance.”
“Few of us have watched someone from Anthropic use Claude Code the way it's intended to be used, inside a real workflow.”
“It's always a pleasure to share talks and hands-on workshops with top-tier professionals.”
42 sessions, grouped by topic. More than four sessions ran at the same time, every hour, for four days.
The flagship track. Anthropic opened it with a standing-room masterclass; PostHog showed how a unicorn ships with it every day.
“Everyone here is wiping skills and hooks like they have a printing machine.”
From the first skill to multi-agent systems, and the memory layer that makes Claude know your company.
“The slot was one hour. We stayed for one hour thirty.”
Scale-ups opening their playbooks, and owners of small businesses leaving with workflows they could run on Monday.
“Sold-out rooms. Waitlists in the hundreds. Ambassadors and builders comparing real setups, not slide decks.”
Laptops open, real products out. Business apps through MCP, a stack wired with Stripe, and non-technical people shipping their first website.
“And hearing "this was one of the best workshops I've attended" melted our hearts.”
Fashion, music and design, with real work on the table: a designer's garments turned into a full campaign in twenty minutes.
“In twenty minutes: a brand book, a shot list, a campaign shoot, copy in three languages, a finished lookbook.”
The Claude Impact Lab closed the week: teams took real challenges from real organisations and built prototypes in a day. The runner-up, Saviesa, interviews the city's elderly by voice so they can teach what they know, through the social centres they already go to.
“Claude Impact Lab just landed in Barcelona and the room is absolutely packed 🤯 People standing at the back, spilling out onto the patio, laptops already open”
The sessions that asked what AI means for how we live and work. Tables of five, no laptops, a public official next to a founder next to a student.
“In a week entirely focused on AI, the most important session was to push the machines away and put humans back at the centre of the debate.”
Out of the box
And the ones people talked about the most.
Barcelona's first. Teams ran through Poblenou to the beach building with voice and AI coding tools, then demoed on the roof.
A photobooth built with Claude, printing strips all week. Build by day, dance by night.
Two hours, a hook, a skein of yarn, no laptops. More people wanted in than there were chairs.
Claude Gaudí, pixel by pixel, stitch by stitch. People left wearing it as a pin.
A barista, a pour-over, and a room of builders tasting instead of typing.
Breathwork on the rooftop at the end of day one.
Cards and questions around a table on the roof, strangers talking within minutes.
A second afternoon of games on the rooftop, and a lot of laughing.
Nando kept the crew roster and answered attendees at the entrance, all week, from a QR code.
Before the doors even opened, people made their own Claude and hung it on the wall.
An hour of art in the middle of a tech week, on Tuesday afternoon.
The speakers under the pergola that carried four nights of DJs.
The Claude Code power users and the people who had never opened a terminal shared the same corridors, and learned from each other. The Claude Conversations put the Generalitat, Foment del Treball, founders, corporates and students at the same tables. Nobody felt out of place.
“I ended up at a table with someone from Catalunya's Digital Ministry, thinking about what it means to bring AI to a public workforce of over 200,000 people”
“You don’t need to have the same background, the same level of technical knowledge, or even the same reason for being there.”
“Some of the best conversations about AI 🤖 do not happen on stage. They happen around a table, with people who see it from completely different angles.”
A sample of the institutions, schools and companies people registered from. A local ecosystem, plus the global teams based in Barcelona.
16 Claude ambassadors ran the rooms, 15 from across Europe and 1 who flew in from Los Angeles. A volunteer crew ran everything else. Speakers gave their best material away for free. And people kept coming back: the same faces, day after day, then up on the roof every evening.
“Sociability is the last human moat.”The title of Tuesday’s panel, and the only line quoted word for word across the week’s posts.
The Claude ambassadors
Michael Whelehan opened a Build Day at 9 and packed the Impact Lab. Florian Steiner walked the partners through the certification and SME owners through Claude Code. Javier Gascón Araujo got Typeform and Qonto on stage. Stefano Amorelli turned Claude into a CFO. Tamás Püski brought his community and the Running Hackathon to the House, where Benjamin Tarenne sat on the jury. Travis Johnson flew in from Los Angeles, because Europe, as Florian put it, has “all the cool events”, and spent the week with the builders. Alexio Cassani taught harness and loop engineering, Geoffrey Rolin Jacquemyns hosted the panel everyone quoted, Alicia Larrazabal brought Radar Venezuela, and Rogier Muller came from Amsterdam for the Impact Lab. Fernanda, Matt and Olivier opened the week and held it together to the last night.
Behind the scenes
More than thirty volunteers gave their week. The bracelets at 8 in the morning, blue for press and green for the rooftop. The door until late. The rooms, the workshop area, the auditorium, the press desk, the rooftop bar, the signs, the chairs, and the wifi when it gave up. Jaume Boix wrote the team brief and rebuilt the roster into four zones mid-week. Anita Beljanina listed every sign and settled the colour of every wristband. Manar Benkraouda, the man in the shadows, kept the tech running for every partner workshop, and still found time to go on stage twice. Les built Nando, the AI that kept the roster and answered the attendees at the entrance. And the others held every shift in between.
Alba · Alberto · Alex · Andres · Anita · Ara · Carlos Andres · Coralie · Daniel · Dmitrii · Emi · Émilie · Gonzalo · Jasmine · Jaume · Jepser · Judith · Julia · Katya · Les · Maite · Mari · Mariia · Marijn · Massa · Menen · Mey · Mohammed · Oksana · Rafa · Rajas · Roxana · Yas · Yuliia
And everyone who jumped in without being on a roster. Thank you, crew.
“There were a LOT of moving pieces, but when everyone pulls together, somehow it all comes to life.”
15 lines picked from more than 400 public LinkedIn posts written during and after the week, quoted exactly.
“The Claude Community House in Barcelona this week was a highlight of my year.”
“I'll say it straight: it's the best AI event I've been to so far. And I've been to quite a few, big and small.”
“Everything was well organized, a lot of fun, and it truly reflected Claude's soul and identity.”
“…amazing what you’ve just started here!”
“it was a strong reminder of why being physically present in a builder community still matters.”
“I was impressed by the quality of both presenters and attendees”
“What’s particularly amazing is what the Claude Community Ambassadors have created collectively.”
“I honestly think I made more connections in the last 4 days than the entire 6 years I’ve lived in Germany…”
“Everyone is becoming a builder, and the real question is no longer how to ship, but what to ship.”
“Claude Community Barcelona House is on fire.”
“In a week entirely focused on AI, the most important session was to push the machines away and put humans back at the centre of the debate.”
“Genuinely the single best investment of time, and the most useful, practical, work thing I've done in a while.”
“I honestly think this is one of the best ways to bring real training to people and understand where digital business and tech are right now, without paying a fortune for a conference ticket.”
“probably the best part of these four days wasn’t any specific tool. it was being around people who are just as excited about technology”
“Hoy ha sido un día mágico en el que he tenido el placer de poder interactuar con mentes brillantes que están reconfigurando el panorama empresarial.”
More than 400 LinkedIn posts, from the first announcement to the recaps that were still coming in a week later.
And before the doors even opened, people had started making their own Custom Claude on claudebcn.com: 216 by the end of the week.
Our home for the week
None of this exists without a roof, and we had a rooftop. B@B Bilbao 128 opened its doors, its auditorium, its rooms and its terrace to a free, community-run week, and trusted us with all of it. A heartfelt thank you to Gerard Beltri, who believed in the idea from the start, and to Marie-Laure Fenet and the Savills team, who made every day possible, from the lifts and the access to the early-morning doors. You were the best hosts a House could ask for.
Four nights on the roof
Fred Papa (DJ Papa), Guillem and Axel (State of Mind), Victor (SAÈZ) and Selen (Selen Us) on the decks, one night each, with the Sagrada behind them. Volta and Borneta behind the bar. Michel Jimenez and the Maison Nicolas team behind the rooftop bar, wine included. Pastries and viennoiseries from Marie Blachère every morning. Coffee from The Miners and Viktor’s Rex Coffee pop-up, and Jepser’s tasting on Thursday. The Claude Booth by Manapix, which Léone and her team kept printing all week. And Fábrica & Co, who welcomed the Impact Lab.
Made possible by
A free, community-run week only exists because companies decided to back it, and people lent us their spaces, their products and their time.
A few of the hundreds of photos taken over the four days.
Pol Ducamp and Abel Belarre Conill behind the lens, all week. Ruth Amat, who brought the press to the House. TV3, Catalunya Ràdio and the journalists who came. The 400+ people who wrote about it. And you, who booked, came, sat on the floor when the chairs ran out, and came back the next day.
We’re already working on it. If you’d like to be part of it again, as an ambassador, a volunteer, a speaker or a partner, just reply to our email. No pressure and no date yet, just a list of people we’d love to build it with.
