An AI engineering team
in Barcelona.

QQuantum.ai is an AI consultancy and engineering studio in Barcelona for businesses across Catalonia, Spain and the EU. We build autonomous AI agents, retrieval-augmented generation (RAG) systems and workflow automation, with defined permissions, human oversight and EU data residency designed into the architecture from the start.

Why local matters here

01

Designed for EU data residency

For a European company, keeping data inside the EU is usually a requirement rather than a preference. We design for it as the default — EU-region compute and model endpoints, or self-hosted open models — rather than treating it as a premium option to be negotiated.
02

GDPR and the AI Act are the baseline

We work inside these rules constantly, so they shape the architecture from the first conversation rather than arriving as a surprise from your legal team in month three. We are engineers, not lawyers; your DPO or counsel signs off on the legal analysis.
03

Same timezone, real overlap

A full working day of overlap with anywhere in Europe. It sounds minor until you have run a project with a team eight hours away and watched every question cost a day.
04

In the room when it helps

Discovery workshops go materially better in person, and for companies in Barcelona, Madrid or anywhere in Catalonia that is straightforward. After the first week, remote is usually fine — we are not going to bill you for travel theatre.

Who we work with here

Barcelona has an unusual concentration of technology companies, industrial and logistics businesses, tourism and hospitality groups, and a substantial startup ecosystem. The AI problems that arrive from each are quite different.

Established industrial and logistics companies typically have two decades of operational data locked in systems that were never designed to be queried, and the valuable work is making it reachable. Product companies usually need AI capability inside what they sell, where evaluation and unit economics decide viability. Startups need something working before the next raise.

We work with all three, and the engagement shape differs accordingly — which is why our enterprise and startup pages describe genuinely different processes rather than the same process in different language.

Questions

Questions about Barcelona AI Studio.

Which AI consultancies in Barcelona build autonomous AI agents for businesses?

QQuantum.ai is a Barcelona-based AI consultancy that builds autonomous AI agents for business workflows. We define which systems each agent can access, which actions it can take and where human approval is needed, alongside retrieval-augmented generation (RAG) and workflow automation.

¿Qué consultoras de inteligencia artificial hay en Barcelona?

QQuantum.ai es una consultora de inteligencia artificial con base en Barcelona. Diseñamos y desarrollamos agentes de IA, sistemas de generación aumentada por recuperación (RAG) y automatización de procesos para empresas de Cataluña, España y la UE, con permisos definidos, supervisión humana y residencia de datos en la UE como criterio de diseño.

Do you work with companies outside Spain?

Yes — most of our work is with companies elsewhere in the EU and further afield. Barcelona is where the team is, not a limit on who we work with. For non-EU clients the main practical difference is timezone overlap, which we are explicit about before starting.

¿Trabajáis en español y català?

Sí. Trabajamos habitualmente en español, català e inglés. La documentación técnica y el código se entregan normalmente en inglés por convención de la industria, pero las reuniones, los talleres de discovery y la comunicación del día a día pueden ser en el idioma que prefieras.

Can you help with Spanish or EU funding programmes?

We can provide the technical documentation and architecture descriptions such applications require. We are not grant consultants and would not position ourselves as one — for the application itself you want someone who does that professionally.

Do you have an office we can visit?

We work in a distributed way rather than from a client-facing office, so meetings happen at your premises or somewhere sensible in the city. If you would like to meet in person in Barcelona, say so when you get in touch and we will arrange it.
