barcelona

Barcelona has one of Europe's strongest games clusters, and this evening at Factor Barcelona brings together the women shaping it — talks, drinks and a room where getting an introduction is easy. Relevant well beyond games: much of the audience works in engine tooling, art pipelines, production and live-ops. Free; currently fully booked.

with Stephany Oliveros (Speaker, HCD Barcelona)

The human-centred design community in Barcelona hosts Stephany Oliveros at One Parc Central for a session on AI, power and the urban environment — how algorithmic systems are being embedded into city services, who gets a say in their design, and what a human-centred practice looks like when the user is a whole population. Low-cost ticket. Relevant to designers, researchers and anyone working on civic or public-sector technology.

An AI Week Barcelona side session at Aticco Sants on what actually changes in a data team once large language models are in the workflow — where Claude and comparable models genuinely shorten the path from question to answer, where they quietly introduce error, and how teams have restructured analysis and documentation practice around them. Practical rather than promotional, and aimed at data analysts, engineers and the people who manage them. Conducted in Spanish.

An AI Week Barcelona side event at Itnig Café in Poblenou, focused on the unglamorous half of applied AI: taking the work that currently eats a team's week and handing it to a model or an agent that reliably does it. Expect concrete workflow examples from operators rather than model benchmarks. Free, and a good fit for founders, operations leads and anyone with a backlog of repetitive process they suspect could be automated.

A deliberately slide-free demo night on the practical mechanics of building AI-powered products, aimed at senior engineers and technical product people. Builders show working systems and talk through what broke, rather than presenting roadmaps. Held at OneCoWork Catedral in Ciutat Vella as part of Barcelona's AI Week. Free.

A community-driven session on managing Red Hat Satellite through Configuration as Code and GitOps principles. The talk covers representing Satellite resources — organisations, content views, activation keys, host groups — as structured YAML via the infra.satellite_configuration Ansible collection, so that infrastructure teams can version, review and reproduce their Satellite estate instead of clicking through a console. Hosted at the Red Hat office in Barcelona. Squarely aimed at platform engineers, SREs and sysadmins running Red Hat at scale.

Bcombinator gathers founders, investors and educators in Poblenou to argue about what learning looks like when AI can do a growing share of the work — and what that means for hiring, training and edtech businesses. A panel followed by live pitches from companies working on the problem. €5 ticket.

Ethereum Engineering Barcelona takes on the question that sits underneath every long-lived cryptographic system: what actually breaks when quantum computers arrive, and what the post-quantum replacements look like in practice. The session runs from the physics of qubits through to the migration problem facing protocols and key infrastructure today. Hosted at AKASHA Hub in Sant Martí. Relevant to cryptography-adjacent engineers, security people and anyone building on-chain systems with a ten-year horizon.

Adsmurai opens its Barcelona office for a September afterwork built around a single question: what actually changes in a marketing or product team once OpenAI's tooling is in daily use. Short talks from practitioners, then drinks on the terrace. Useful for growth and product people who want implementation detail rather than another keynote.

Esade eWorks and the Barcelona Supercomputing Center host two AI-focused sessions at Tech Barcelona's Pier 07 as an official AI Summit side event, followed by open founder networking. The BSC involvement makes this one of the few AI Week events with genuine research weight behind it. Free; currently fully booked.

with Marina Barguño (Founder, Nora Talent & Research) · Magda Kufrej (Founder, Work Ally)

A ninety-minute roundtable arguing that "AI-literate" has become the most requested and least defined skill in hiring. It draws on a Nora Research study of non-technical job postings across the UK and Europe which found that fewer than one in ten employers mention AI in non-technical roles, and almost none define a testable level. Attendees leave with three concrete levels of AI literacy and a way to write and interview for them. An official AI Week Barcelona side event.

A hands-on building workshop in the run-up to the AI Summit, run with Lyra AI and Make. Laptops open, groups of five to ten, each with an experienced lead — you arrive with something you want to build and leave having actually built it. Better suited to people who want to ship than to people who want an overview. Free; venue disclosed to registered attendees.

HiveFest is the annual gathering of the Hive blockchain ecosystem — part reunion, part conference, part social event — and its eleventh edition lands in Barcelona under the banner Architecting Decentralization. Contributors from more than 165 countries come together to work through the future of decentralised social media, on-chain governance and Web3 infrastructure. The Barcelona sessions run from AKASHA Hub in Sant Martí. Worth a look for anyone building in Web3 who wants a non-EVM perspective on decentralised applications.

with Matt Roberts (Community Organiser, Claude Code Community)

A hands-on Claude Code workshop hosted in the Dynatrace Barcelona lab. Bring a laptop and a real repository: the session works through agentic coding patterns, setting up project context, and the habits that separate a demo from something you would actually ship. Run by the Claude Code community organisers alongside local engineers.

The third edition of HackBarna takes over Norrsken House Barcelona for two days with more than 150 hackers, workshops, technical sessions, demos and networking. Deliberately open to no-code builders as well as full-stack engineers, which keeps the project mix unusually varied. The official pre-summit hackathon for AI Summit Barcelona, and free to enter.

A morning coffee session at the Claude Barcelona House on Carrer de Bilbao, opening the week of AI Summit activity in the city. Informal, hands-on and built around people actually building with Claude — bring a project, a prompt problem or a half-finished agent and work on it alongside others doing the same. Free, and the gentlest entry point into the Claude Barcelona House programme that runs across the same week.

An AI Summit side event at Pier 01 Barcelona Tech City with no stage and no slides — just the terrace, a glass of good wine and the people who will be at the Summit the following morning. A sensible way to arrive at the main conference already knowing a few faces. Free.

An informal meetup at eDreams ODIGEO for people building with AI rather than talking about it: dev tools, agent frameworks, RAG, vibe coding and Claude Code, shared by the practitioners using them. Part of AI Week, and one of the more technical entries in it. Free.

An AI Week Barcelona side session on the organisational problem rather than the technical one: what has to change in a company's structure, hiring and decision-making for AI to stop being a team and start being how the business runs. Held on Avinguda Diagonal ahead of the main AI Summit. Most relevant to founders, CTOs and heads of engineering who already have AI capability in-house and are working out how to distribute it.

with Dr. Florian Steiner (Organiser, Claude Code Community Munich)

The AI Summit week edition of the Claude Code workshop, run at Claude Barcelona House. A working session rather than a talk: attendees set up agentic workflows on their own projects with organisers from the Munich and Barcelona Claude Code communities on hand. Suited to engineers already using AI tooling who want to go past autocomplete.

with Jérémie Benhamou (Host, The Tech Nation)

Jérémie Benhamou walks through the configuration, context management and review habits that separate occasional Claude Code users from people who run most of their work through it. Practical, opinionated, and aimed at engineers and technical founders who have already tried agentic coding and hit its rough edges.

A session at Barcelona Health Hub on what the EU AI Act actually requires of medical devices that incorporate artificial intelligence, and how its obligations interact with the existing MDR regime — classification, conformity assessment, post-market monitoring and the timeline manufacturers are now working against. Free, and one of the more concretely useful regulatory sessions for healthtech companies in the window. Conducted in Spanish.

Southern Europe's largest AI conference returns to the World Trade Center for two days, with more than 10,000 attendees, 200-plus speakers and seven tracks spanning research, infrastructure, applied enterprise AI and policy. It anchors a city-wide AI Week of roughly fifty satellite events, so the fringe is worth planning for as much as the main programme. Paid, from €345 including VAT; no single-day pass.

The Barcelona JavaScript community meets at Itnig Café in Poblenou. BarcelonaJS is one of the longer-running developer communities in the city and the format is the classic one: a couple of technical talks on the current state of the JavaScript and TypeScript ecosystem, then drinks and conversation. Free, and worth putting in the calendar if you write front-end or Node for a living.

Flashpoint Capital runs a closed-door session at the W Barcelona on the actual mechanics of building a US company from Spain: the Delaware flip, IP assignment, US payroll, visas and what all of it does to a founder's tax position. Also covers when the flip should happen and which metrics US VCs look for. Free, but registration is screened.

with Lüset Pardo Arditi (Co-founder, Lumoo)

A fashtech working session at Claude Barcelona House: the Lumoo team shows how they use Claude across design iteration, product copy and studio operations. Concrete and domain-specific, which makes it one of the more interesting AI sessions in the AI Summit fringe for anyone working at the design-and-tech crossover.

Directors from Arcano, Alantra and Clearwater explain how to break into M&A and where the mid-market is heading in 2026, hosted at La Salle — Universitat Ramon Llull. Directly useful for anyone in startup finance, corporate development or fundraising who wants to understand how the buy side is currently reading tech assets. Networking follows the panel.

A full-day build session at the Claude Barcelona House, running alongside AI Summit Barcelona week. The format is hands-on: you arrive with something you want to ship, work through it with Claude and with other builders in the room, and leave with a working artefact rather than a set of notes. Suited to engineers, technical founders and product people who already write or read code. Free, but capacity is limited and the day is structured, so register early.

An AI Summit Barcelona side session at SAGE in Sant Martí on the governance and inclusion questions that the deployment wave has outrun — who is represented in training data and evaluation, who carries the cost of a wrong output, and what responsible practice looks like for a team shipping this quarter rather than legislating for next year. A morning session, free, and relevant to product leaders, policy people and engineers alike.

The ClickHouse team hosts an evening on real-time analytics at scale at Manychat's Barcelona office — what is new in the ClickHouse ecosystem, how teams are wiring analytics into AI products, and the usual war stories about query performance. Speakers announced closer to the date. Free.

with James Allison (Senior Staff Engineer, Wealth, Monzo)

Monzo's Barcelona engineers open up about how the bank actually builds with AI: two practical talks on agents and on automating prompt engineering, then questions over drinks and pizza. Named speakers from the Wealth team and a strong RSVP count make this one of the better engineering evenings in the window for anyone shipping LLM features in a regulated environment.

Barcelona Game Creators runs a structured speed-networking session at Cotxeres de Sants in the run-up to IndieDevDay. Designed for game developers, artists, audio people and publishers to find collaborators quickly rather than circle a room. Barcelona's games cluster is one of the densest in southern Europe and this is where its junior and mid-level talent actually meets.

The Claude Barcelona House closes its week with a day aimed at non-profit, public-interest and social-impact organisations working out where AI fits in their operations. It is a working session rather than a showcase: teams bring a real constraint — casework backlogs, reporting burden, translation, grant writing — and build against it with support in the room. Free, and unusually practical for a sector that rarely gets hands-on AI programming.

A hackathon built around running data — wearables, route models, training APIs — hosted at Claude Barcelona House with a long bench of community organisers. Unusual format, genuinely hands-on, and a good entry point for engineers who want a build day with a clear domain rather than an open-ended prompt.

A special edition of the Power BI and Microsoft Fabric Barcelona community held on the eve of FabCon Europe, which brings the global Fabric conference to the CCIB the following day. The afternoon runs three advanced technical sessions delivered by international speakers from the Power BI and Fabric ecosystem, followed by networking. All sessions are in English. Held at La Fabrica & Co in Poblenou — a straightforward way to get a head start on FabCon week without a conference ticket.

Europe's largest Microsoft data and AI conference runs four days at the CCIB, opening with a tutorial day on 28 September and continuing with more than 130 sessions on Fabric, SQL, Power BI and Copilot. Squarely aimed at data engineers, analytics leads and BI practitioners in enterprises rather than at startups. Paid, from €1,595 plus VAT for the three-day pass.

Iniciativa Barcelona Open Data marks a decade of work with a retrospective session at Espai Francesca Bonnemaison on how the value and the politics of data have shifted since 2016 — from open-data portals as a transparency project to data as the substrate of machine learning, and what that has done to public-interest data work. Free. Note: the session is conducted in Catalan.

A one-day cybersecurity conference at DFactory Barcelona in the Zona Franca, bringing together practitioners, vendors and CISOs for talks and structured networking. Doors at 08:30, closing at 15:30. Pricing is not published on the listing — check the registration page.

BcnKode marks fifteen years of Kotlin at Basetis's offices inside La Pedrera. Talks on where the language has ended up — multiplatform, server-side and the state of Android tooling — followed by drinks. One of the longest-running mobile developer communities in Barcelona. Free.

with Xesca Alabart (CEO, EasySpecs Labs)

Xesca Alabart, CEO of EasySpecs Labs, runs a live session on spec-driven development for agentic systems — how to write specifications an agent can actually be held to, and what Trust Engineering by Design means in practice. Live Q&A throughout. Organised by Barcelona's Product, Design & Technology Networking Group.

The first gathering of the Barcelona SaaS Founders Circle: an evening for SaaS founders and co-founders focused on scaling in 2026 to compare notes on pricing, churn and go-to-market. Small by design, first edition, and worth catching before it gets crowded.

with Pep Martorell (Partner, Invivo Partners) · Luis Pareras (Partner, Invivo Partners)

Tech Barcelona and EAE Business School host Pep Martorell and Luis Pareras of Invivo Partners for a small-group Petit Comitech session. A year ago the pair launched Invivo Ventures AI, a €100 million fund backing the next generation of artificial intelligence, science and deeptech startups; this is a chance to hear how they are actually deploying it and what they are screening for. The venue is confirmed to registrants. Conducted in Spanish.

Fair Cultures runs its third future-of-work conference at TBS Education Barcelona across three stages: People & Culture, HR Infrastructure and AI, and hands-on Labs. Aimed at people leaders and HR-tech builders rather than at recruiters. Cross-listed on the DeepTech Talks Barcelona community calendar.

Tech Barcelona's recurring afterwork on the Pier01 terrace, open to the whole community rather than to members only. Member companies get a two-minute elevator pitch slot, so there is a light programme, but the substance is the room — this is the most reliable way to meet people across Barcelona's digital and tech sector in one evening. Free, 18:00–20:00, on the waterfront at Palau de Mar.

The DevOpsDays Barcelona community meets at Allianz Technology Spain for two talks and the usual hallway track. A reliable, well-attended engineering meetup with a named host venue and a real agenda — one of the steadier infrastructure communities in the city.

The opening edition of Talent-R's CISO Legal Tech strand, part of its Talented People series, looking at how artificial intelligence is reshaping legal operations — contract review and drafting, matter triage, knowledge management and the vendor decisions that follow. Aimed at in-house counsel, legal ops leads and the technology people who build for them. Held at Talent-R in Barcelona; registration is via Luma and required. Conducted in Spanish.

A monthly networking evening at Educo for people building at the intersection of education and technology — founders, product people, researchers and teachers. Barcelona's edtech scene is small but active, and this is its regular meeting point.

The third edition of Women in Fabric, a full day dedicated to Microsoft Fabric, Power BI, AI and data engineering at BAU College of Arts and Design. Three tracks, 24 sessions and 30 international speakers, running from beginner to advanced level in both Spanish and English. A 100% in-person community event set up to make women's technical work in the Microsoft data ecosystem visible — but the programme is open and the sessions are technical, so it is worth the day whoever you are.

Three days at Norrsken House Barcelona bringing together more than four hundred female GPs, LPs, investors, founders and operators. Closed-format sessions on fund mechanics and allocation alongside open networking. Paid; see the summit site for tiers.

Five minutes, two people, then rotate — Women & Tech Barcelona runs a speed-networking format at La Fuga in which you have one-to-one conversations with fifteen or more women in tech over the course of an evening. No pitches and no performing; the design is deliberately gentle and the stated aim is finding a collaborator, mentor, co-founder or friend rather than a lead. A markedly better structure than an open-floor mixer if you find those hard work.

A monthly gathering at La Fuga for product strategists, growth specialists and people working on AI implementation. The setting is informal but the focus is narrow — product innovation, growth strategy and how teams are actually putting AI into products — which tends to produce more substantive conversation than a general tech mixer. Free, and one of the more reliable recurring product meetups in Barcelona.
