Technology, tuned. — Artificial intelligence · Custom software · Brand and digital product · Accessibility and security
Engineering, designand artificial intelligence,tuned to how you work.
We build the software, the AI systems and the brand a company needs — one team from first sketch to production. Fixed scope and price, weekly deliveries, results you can measure. No hype.
What we do and in what order
Four disciplines in the same team. No subcontractors and no handovers: the people who think the work are the people who do it.
The four disciplines
Agents that do the work, not agents that chat. Models tuned on your own data — and running on your own machines when the data cannot leave — continuous evaluation of whether they get it right, and cost sized to the job: almost no task needs the most expensive model on the market.
Applications and platforms, built to fit. What no off-the-shelf tool solves: integrations, APIs and systems written for the way you actually work. The code is yours, in your repository, from day one.
Identity, digital product and motion. Brand and design systems that scale from the business card to the product, interfaces that need no manual, and motion treated as part of the brand rather than decoration added at the end.
What we build holds up. Measured speed, accessibility to EN 301 549 — enforceable across the EU since 2025, including for companies selling into it from outside — security, and the traceability the European AI regulation asks of systems that use it.
And where to start
- 01TuneA short diagnosis with a fixed scope: what is out of tune, what should be fixed first and what can wait.Before building, listen→
- 02BuildWhat the diagnosis decided, made. By the same team that thought it, with no handover between the people who design and the people who ship.Design and code, same hands→
- 03Keep in tuneAn instrument drifts with time and use. So does software: dependencies change, models change, content changes, the business changes.Nothing is tuned once→

How we work
- 1·
Listen
Audit or brief. We understand before we propose.
- 2·
Agree
Priorities and scope in writing. What is in — and what is not.
- 3·
Ship
Design, code and AI. Weekly deliveries, not a big reveal.
- 4·
Measure
We measure what changes, not what shipped. Training so it's yours.
Technology doesn't have to sound like noise.

What we have tuned
Two examples of what happens when engineering, design and artificial intelligence live in the same team.
- Micblau PiscinesIdentity, site and technical assistant
Water treatment for public and private pools. We rebuilt the brand and the site in three languages — 66 routes, 86 redirects from the old site — and built a technical assistant over their own document library: 67 documents, 1,148 indexed chunks, and an answer that always cites the sheet and the year it came from.
- SecureConverterProduct and engineering
Processes video, image, audio and documents with AI that runs entirely in the browser: the content never leaves the machine it is on. Privacy by architecture rather than by policy — the only kind anyone can verify.
Who signs the work

What we learn building
A real problem from a real project, how it was solved and what it cost. With the numbers, and with what did not work. Once a month — and if there is nothing worth sending, we skip it.
