About

An AI engineering studio
built on precision.

An AI systems engineering studio based in Barcelona. Building software since 2006; building agents, retrieval architectures and automation now.

WHERE WE COME FROM

The Architecture of Intelligence

2006 — FIRST COMPANY SOFTWARE

Our founders have been building software since 2006, through earlier companies, for banks, retailers, broadcasters and charities. QQuantum.ai is the current studio. Just as Gaudí observed that there are no straight lines in nature, we understand that modern business operations are deeply complex, non-linear ecosystems.

TODAY BARCELONA

Our autonomous agents are designed to weave through this complexity, handling outbound sales, dynamic SEO, and internal operations with measured accuracy and a human escalation path.

HOW WE WORK
01

Senior people, small team

The people on your first call are the people who build the system. That means we take fewer projects at once, and it means nobody hands your work to a junior after the sale.
02

We will talk you out of things

A meaningful share of enquiries resolve to an off-the-shelf product or a process fix that needs no AI. Saying so costs us a project and earns the next one.
03

You keep everything

Code in your repositories, infrastructure in your accounts, documented decisions. If your team wants to take over, that is a planned outcome rather than a renegotiation.
BASE OF OPERATIONS

Engineered in Barcelona

QQuantum.ai works from Barcelona, with clients across the EU and further afield. The city gives us a full working day of overlap with the rest of Europe, the same regulatory regime as most of our clients, and a habit — borrowed from its most famous architect — of treating structure as the design rather than something added afterwards.

We build systems meant to be robust and adaptable: evaluated against real data, monitored in production, and handed over as code you own.

Sonora

Cognitive AI Ltd · 2026

A free sound-wellness app, described by its publisher as AI sound therapy that reads a short vocal sample at the start of a session and generates a soundscape for that moment. We designed and built the website and its backend, produced assets for the iOS and Android apps, and supported the application prototype.
