Your AI agents, built in Lille.
root is a Lille-based company. We design and deploy agents that work on your data, inside your tools, hosted in France: for firms and companies in the region, and across the country.
AI agency in Lille
Looking for an AI agency in Lille?
The word is imperfect, but the question is the right one. root builds AI agents you own: they run on your own instance, in France, and your team learns to drive them. A service contract ends at delivery; an agent you own keeps working.
You own the result
The agent, its configuration and its data stay yours. No black-box subscription, no dependency on a rented platform.
Your data stays in France
A dedicated instance per client, sovereign hosting, an audit log. Compliance is verified, not promised.
Your team stays in charge
We train your people to put their agents to work. Humans keep judgment and signature.
The North
Sovereign infrastructure runs through the North.
In June 2026, DATA4 announced its largest data-center campus in Escaudain, near Valenciennes: 5 billion euros, 700 MW, built for AI. The region is becoming an anchor of Europe's digital infrastructure. We are at home here: root has operated a sovereign hosting foundation for years, and your agents are built on that infrastructure culture.
5 billion euros in Escaudain
DATA4's largest campus: four data centers, 700 MW, on a converted industrial site.
A foundation we operate, not promise
root comes from sovereign hosting: compliance by architecture is our starting point, not an afterthought.
Lille, a tech stronghold
EuraTechnologies, the French Tech ecosystem, engineering schools: the metropolis trains and attracts the people who build digital systems.
Who we serve
From Lille, we equip firms and companies.
Regulated professions first: accounting, law, healthcare. And every company that wants to keep control of its data: SMEs, mid-caps, finance teams, CIOs. The region is our base, not our perimeter.
Straight questions
The questions we hear first.
Is root an AI agency?
root is a Lille-based company that designs, deploys and operates AI agents. Unlike a classic agency, we do not sell consulting days: we deliver agents you own, and we support your team to autonomy.
Do you only work in Hauts-de-France?
No. Lille is our base: in-person workshops are easy to set up, from Dunkirk to Valenciennes. The rest of France gets the same service, through video calls and remote deployment.
Where is the data hosted?
In France, on a dedicated instance per client, with an audit log and reversibility. By default, no US entity in the data path.
How does a project start?
With a 30-minute conversation about your processes. We then map your data and AI usage, and the first agent reaches production within weeks.
Let's talk, in Lille or remotely.
Tell us about your processes: we will tell you what an agent can take over, what it changes for your team, and how to do it without your data leaving France.
