Ladies Wine & Design Barcelona runs its sixth Portfolio Club at The Social Hub in Poblenou: a structured evening in which designers bring work in progress and get direct, constructive review from peers and from more senior practitioners. Far more useful than a generic design meetup if you are preparing a portfolio for a job search or a freelance pitch. Free, open to designers at any stage, conducted in Spanish.

The Barcelona observability community returns from the summer break, this time hosted in Plain Concepts' offices in L'Esquerra de l'Eixample. Grafana & Friends is the local chapter for engineers working with Grafana, Prometheus, Loki, Tempo and the wider open-source monitoring stack, backed by Grafana Labs and with 76 reviews behind it. The agenda and speaker line-up are still to be published — the organisers have asked people to save the date first — but the format is consistent: a couple of practitioner talks, then networking over drinks. Free, with 47 places still open at the time of listing. Sessions are typically delivered in Spanish.

Day three of Media Party Barcelona is a one-day build sprint at BIT Habitat, Barcelona's urban innovation centre in Poblenou. Around 100–120 selected developers, data scientists, journalists and designers form multidisciplinary teams and ship open-source prototypes across three tracks: workflow automation and agentic journalism, the post-search publisher economy, and information integrity and verification. Cloudflare is headline sponsor, supplying infrastructure and AI developer tooling plus its own challenge track with prizes tied to its developer ecosystem; small grant prizes are also awarded. Teams pitch and demo before the day closes. Useful for engineers who want a real applied-AI problem for a day, and for anyone working on trust and provenance on the web.

Barcelona's AI week brings big stages and big claims; this is the opposite. Ninety minutes in Itnig Café before the working day starts, with a small group of founders and no programme beyond good coffee and conversations that go somewhere. Hosted by Founders & Coffee with Itnig in Poblenou. Registration is by approval and places are deliberately limited.

Itnig's first Tertulia of the new season and the only event on its calendar in the window — the Barcelona-born ecosystem that combines a community, an early-stage fund, two coworkings and one of Spain's most-listened-to startup podcasts. The evening follows its established shape: a live-recorded discussion of the month in Spanish tech, the open-mic "De Cero a Un Millón" block where anyone can put a business question to the panel, a startup pitching live to investors, and an afterwork networking session in the café. Guest line-up is announced closer to the date. General admission €10; the tertulia is also streamed on YouTube. Conducted in Spanish.

Aticco Ventures hosts a round table at the Barcelona Finance Hub on Passeig de Gràcia covering go-to-market strategy for B2B companies: strategies, lessons learned and real cases for building a GTM motion that actually produces pipeline, customers and growth rather than activity. Free, practical, and aimed at B2B founders, sales leads and growth people rather than at marketers generally. Conducted in Spanish.

Startup Oasis, the largest English-speaking tech and business community in Andalusia, brings its bi-weekly morning coffee format to Barcelona for the first time. There is no agenda and no moderation — the whole point is unfiltered conversation between founders, developers, designers, product people and digital nomads over coffee. If you have been looking for a Barcelona equivalent of the Málaga scene's open-door networking, this is the launch edition and a good moment to shape what it becomes.

The first meetup of a new Databricks user community in Barcelona, deliberately kept simple: coffee, conversation and Databricks, with no slides and no talks. The organisers want to meet the people already working with the platform in the city, swap real-world experience, and collect ideas for what the group should run next — hands-on workshops, technical deep dives, or use-case sessions. Worth attending if you work in data engineering, analytics or ML platform work and want a say in how this community takes shape. Held in a mix of English and Spanish.

The season opener for Barcelona's Open Data School at Cibernàrium, run by Iniciativa Barcelona Open Data. The workshop covers the reuse of open data end to end: locating sources, assessing licence and quality, cleaning, and turning a public dataset into something a service or an analysis can rest on. Free, and one of the few consistently practical public-data training programmes in the city. Note: the session is conducted in Catalan.

InnoIT Consulting opens its autumn season days before the AI Summit, together with Gentleman Programming. Three talks: the road from LLMs to agents, building agentic applications with Angular and Genkit, and how much you should trust software written by AI. Food and drinks follow. Held in Spanish at InnoIT's Eixample offices; free, but places go quickly.

Foment del Treball's congress on AI and business competitiveness, run across five formats in one day: keynotes on the main stage, live labs, one-to-one technology meetings, invite-only sessions and open networking. DIH4CAT runs matchmaking alongside. Aimed squarely at operators in established companies working out what to adopt, rather than at startups. Free with registration.

Claude Code Barcelona restarts after the summer at Runroom's Gràcia office. An evening for engineers already using agentic coding tools day to day: what has changed in the tooling over the summer, what people have actually shipped with it, and where it still falls down. Hands-on and opinionated rather than introductory.

Europe's largest institutional digital-assets gathering returns to the Palau de Congressos de Catalunya for its twelfth edition, with around 6,000 attendees and 300 speakers over two days. The agenda leans towards regulation, tokenisation, stablecoins and institutional adoption rather than retail crypto, which makes it unusually useful for fintech operators, legal and compliance people and infrastructure builders. Paid, from €500 plus VAT.

Python Barcelona restarts its season with Dow Jones and PandaDoc, hosting two talks at the Dow Jones office on Diagonal. The first covers beating an established benchmark for a document classification model — the practical story of getting a 14-billion-parameter classifier to hold up against an entrenched baseline. The second argues that LLMs cannot make your code simpler, a useful counterweight to the current wave of AI-assisted development claims. Doors at 18:15, talks from 18:30, networking from 20:00. Free, in English, and one of the most consistently technical meetups in the city.

UX Hub Barcelona takes over Wallapop's headquarters for a deliberately contrarian evening on experimentation: where A/B testing quietly misleads product teams, what it cannot tell you, and what to do instead. Aimed at product managers, designers and researchers rather than statisticians. One of the best-attended product events in the city — nearly ninety people already registered.

An official European Blockchain Convention side event hosted by XRPL Commons with Peersyst, held in a café in the Eixample rather than a conference hall. Expect a technical, developer-facing evening on what is being built on the XRP Ledger, plus the kind of conversation that is easier to have away from the main convention floor. Free, but capacity is small.

A WEMatter Global conversation ahead of the AI Summit, held at the SBS Swiss Business School campus in Sant Martí. The session looks at investing, asset ownership and how an economy increasingly shaped by AI changes the calculus for women building long-term wealth. Practical rather than motivational, and free to attend.

Three days at Norrsken House Barcelona on where AI value actually accrues: shared-value models, the ownership economy and the infrastructure needed for trusted commerce. Organised by Common Share, it draws founders, investors and policy people rather than a general tech audience. Paid — one-day passes from €499 plus VAT, with reduced NGO and startup rates.

The first edition of Connect Day, run by the Barcelona Entrepreneurs and Startups community at La Fabrica &Co in Poblenou. The premise is that most networking events hand you business cards; this one is designed to send you home with a shortlist — vetted providers you can actually hire, and founders working on comparable problems. Expect a structured afternoon and evening rather than an open bar, aimed at entrepreneurs and operators who need working relationships rather than contacts. Early-bird tickets have sold out; first-release tickets are €15 until 13 September.

The third edition of Homo Promptus's Barcelona afterwork for people building with and around AI, held at Villa Emilia. The format sits between a meetup and a drinks evening — short input, then conversation — and the community skews towards practitioners actually shipping AI features rather than observers. Free. Held in a mix of Spanish, English and French.

CodeWomen+ runs a practical coding-challenge evening at the Canòdrom, Barcelona's public digital and democratic innovation centre. Participants work through problems together in small groups — useful interview preparation, and a low-pressure way to keep algorithmic practice alive if your day job has drifted away from it. Free, open to women and non-binary people in tech at any level.

Fuckup Nights is a global series running in more than 250 cities in which speakers stand up in front of a room of strangers and walk through a professional failure — what they did, what it cost, and what they took from it. The Barcelona chapter reaches its sixty-second volume at Aticco Bailén. It is a genuinely different format from the usual founder-stage optimism, and the honesty tends to produce better conversations afterwards than a standard panel does. Paid ticket, external registration via Tickettailor.

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.

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.

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.

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.

Tech Barcelona turns its Tech Spirit format over to a women's edition at Pier 07, bringing together founders, executives, researchers and technologists to work through the ideas and technologies shaping what comes next. The framing is deliberately data-led: women make up roughly 32% of digital employment in Spain, which is progress and not enough, and the morning is built around what closes the remaining gap rather than around restating the statistic. A public activity, open to everyone, running 09:00–14:00.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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 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 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.
