AI consulting & engineering firm · Since 2020
AI, yes.
Control stays
with you.
We handle all the technical work so you stay in charge: your sensitive data can stay in France on our own servers, the AI is tailored to your business, and your teams are trained to use it.
What we master
The whole chain, with proof
From our servers to training your teams, every step is handled by JustAI and links to the page that proves it. Your project only uses the steps it needs.
Our own servers in France
We own our computing servers (GPUs), hosted in France by a French provider, with no third-party cloud. For sensitive data, a sovereign mode ensures none of it goes to a US provider.
AI tailored to your business
We start from open AI models (open-weight) that can be inspected, adapt them to your real use cases, then bind them to your own rules. Our research is published.
Brio, our AI platform
An assistant and AI agents that carry out tasks for you. Built by JustAI, Brio follows all of ANSSI's security recommendations for AI systems.
Your software in 4 weeks
AI writes the code; our engineers and AI PhDs review it. Your custom software goes live in 4 weeks, from €20,000 excl. VAT. The source code is yours.
Your teams, trained
From executives to business teams, we train everyone to use AI day to day, from first steps to full autonomy. Qualiopi-certified training provider.

Why JustAI
Because technology without vision is just noise
Too many AI projects fail because they start with the solution before understanding the problem. Our approach is the opposite: we start with your business challenges, your real constraints, your teams. Technology comes after, in service of a clear objective.
We don't sell AI. We build systems that work, are maintainable, and create lasting value.
AI is a tool, not an end
Projects that start with 'we want AI' fail. Those that start with 'we want to solve this problem' succeed.
Data is the real issue
The best model in the world can't compensate for poor data quality. Before algorithms, we talk governance.
Humans remain at the center
The most effective AI systems augment human capabilities. Adoption relies on trust, not obligation.
Simplicity is a strength
A simple model in production is worth more than a sophisticated model in a notebook.
