What we deliver
Three things, done properly.
- 01
Agents
AI agents wired into your tools that handle a real workflow end to end, with a human approving where it matters.
- 02
Products
Web apps, SaaS, websites and mobile apps built with AI at the core: secure, fast, and maintainable by your next hire.
- 03
Teams
AI training one-to-one, in private groups or company-wide, on your own cases. So the tool gets used, not just demoed.
Expertise
Ten areas of expertise. One accountable team.
From AI strategy to production, and the years after. One team holds the thread, from the first workshop to the dashboards.
AI
Agents and AI features that genuinely save time, and the teams trained to use them.
- 01
AI agents & automation
Agents that run one business workflow end to end, with tools, human approval at the right steps, evals, logs and a cost ceiling.

Generative AI in products
Copilots, semantic search, RAG over your documents, summaries and extraction, shipped inside your product with evals, guardrails and a cost budget.
- 03
AI training
1:1 coaching, private groups or company programmes. Four tracks, from AI strategy and risk to coding agents, worked on your own cases.
Build
Apps, SaaS, websites and mobile apps, designed for AI from day one.

How we do AI
Fewer demos. More production.
- 01
One case, one metric
We start from a real workflow and a number you already track. If the value cannot be measured, we do not build it.
- 02
Humans stay in charge
Human approval where mistakes are expensive, a log of every action, a way back. The agent assists; it does not decide alone.
- 03
Evals before demos
Every agent is tested on a set of real cases before anyone sees it. We know its error rate before your users do.
- 04
Your data stays yours
Model choice driven by data sensitivity, European hosting available, no training on your content. Code, accounts and prompts belong to you.
AI training
Train your teams, not just equip them.
An AI assistant subscription changes nothing on its own. Our training starts from your documents, your tools and your cases, so everyone leaves with habits they apply the next morning.
- 01
One-to-one
Private coaching for a founder, executive or expert: your topics, your pace, in confidence.
- 02
Private group
A closed session for a leadership team or a project team, around a shared goal.
- 03
Company
Role-based programmes for the whole organisation, on site in Paris or remote: leaders, operations, developers.
Method
From use case to production, without detours.
- 01 / 04
Frame
One use case, one success metric, the real state of your data. A written scope and an honest estimate.
- 02 / 04
Prototype
A prototype that works on your real cases, tested by the people who will use it.
- 03 / 04
Harden
Evals, security, monitoring, cost control. What separates a demo from a dependable tool.
- 04 / 04
Scale
Go-live, team training, then the next workflows.
In-house product
We build our own products too.
BookCab.tech is a SaaS for independent chauffeur and VTC drivers in France: booking site, back office and automations. The studio designed it, builds it and runs it every day. It keeps us honest: we live with our own architecture decisions.

Questions we are asked
Does our data go to OpenAI or elsewhere?
Only if you decide so. We pick the model by data sensitivity: US providers under contracts that exclude training on your content, Mistral with European hosting, or an open model hosted on your side. The choice is written down and justified before we build.
Do we need a tech team to get started with AI?
No. We can handle the technical side entirely and train your teams to use what we build. If you have developers, we work with them and hand over the know-how.
Do you offer AI training for executives?
Yes, one-to-one or in a private group: strategy, use cases, risks, the EU AI Act, and practice on your own topics. Company programmes then cover operational and technical teams.
Where is the studio?
In Paris, registered in Boulogne-Billancourt. We work on site when it helps and remotely otherwise, in English or French.
