Sovereign AIModular & prefab
Eclairion runs a modular high-density colocation campus south of Paris built entirely from container modules, supporting 30kW to 200kW per rack with air, direct-liquid and immersion cooling. Mistral's first dedicated GPU training cluster is hosted there in partnership with Fluidstack. EDF has since selected Eclairion for large AI data center projects at former power station sites in France.
Ecosystem functionEurope's sovereign-AI landlord of choice, differentiated by proving that container-module colocation can host frontier-scale training runs rather than just edge or burst capacity.
