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 management

Renewable power capacity across the AI-Grid, from biogas, solar and wind producers.

EU HARDWARE · EU ENERGY · EU OPERATOR
01

Sovereign by construction

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

GRID
02

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.

+ MODULE
03

Built in house

Modular shells we design and build for our own needs. A site grows by adding modules.

How it works

Power in,
tokens out

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.

AVAILABLE POWERGPU LOADILLUSTRATIVE

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.

GPU loopLocal heat
DigesterDryingBuildings

Heat reused locally

The cooling loop hands GPU heat to the site and its neighbours. Selling that heat pays for the cooling.

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.

For energy producers

Join the AI-Grid.

Farms, industrial buildings, renewable producers. If you have 100 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.
