About us
MAT Agency is a French AI agency, founded in Annecy by Matthieu de La Selle. Its name comes from the first three letters of Matthieu, and from the image that guides its work: AI is the wind. What moves a business forward is the mast that holds the sails: a solid AI structure, carrying AI agents that can really work.
These three letters are also our method: Measure how you work, Automate what can be automated with AI agents, Transfer so your team stays independent.
Before offering it to others, Matthieu did it himself: he built ConciergeOS, complete software for short-term rental concierge services, then the tools of Capexim, our partner specialised in property advisory and investment.

Matthieu de La Selle
Founder · The technology
Certified in artificial intelligence, he designs AI agent systems that are both powerful and simple to use, built for the field.
Technology shouldn't replace people: it should free them.
We wanted a human-sized business, close to its clients, whatever their trade: retail, crafts, services, practices, property or short-term rentals. We always start from the way you work, never from software to sell.
