Sovereign by construction
Hardware, energy and operator in the EU. Open-weight models, and your data stays in the EU.

Inference doesn't need gigafactories. It needs a grid of micro-sites.

The foundation
The foundation for sovereign AI
AI is short of power. Micro-sites have it: farms, industrial buildings, renewable producers. We put the GPUs where the energy is and wire every site into one grid, without compromising on three things.
20MW
Under managementRenewable power capacity across the AI-Grid, from biogas, solar and wind producers.
Energy at the source
Racks sit where the power is: biogas, solar, wind, or an existing grid interconnection. Capacity does not wait years for new lines.
Built in house
Modular shells we design and build for our own needs. A site grows by adding modules.
How it worksPower in,

Six layers between a site's energy and your API call. We build and run all of them.

Europe first
Europe's first AI-Grid.
Distributed and highly resilient.
We focus on micro-sites with spare power: farms, industrial buildings, renewable producers or a plain grid connection. We start in France and Belgium, then Germany. By December 2029 the AI-Grid reaches 248 sites, all feeding one API. Our 2029 plan targets 85% renewable power.

Build on the AI-Grid
Start with an endpoint. Move to dedicated capacity when your volume justifies it. Same grid underneath.

Serverless inference
Open-weight models behind an API. You send prompts, we bill tokens.
AMDNVIDIAfree
GPU by the hour
AMD and NVIDIA GPUs on bare metal or Kubernetes, for fine-tuning, batch jobs and evaluation.
Reserved clusters
A full module dedicated to you, on a site you can visit, on monthly or yearly terms.
Energy-aware scheduling
Jobs run where power is available, and GPU power follows each site's energy budget.
Interconnected AI-Grid
Failover between sites, load balancing across the grid, and jobs placed where energy is available and cheapest.
Heat reused locally
The cooling loop hands GPU heat to the site and its neighbours. Selling that heat pays for the cooling.
GPU-MOD-01
Module
Modular. Container-based. Built in house.
We design and build our modules ourselves, for our own needs. Each one holds a GPU rack, its cooling loop and its power backup, next to the producer.

Farms, industrial buildings, renewable producers. If you have 200 kW or more of spare power and a little land, we install a module on your site, buy your energy and give the heat back.
