What Eclairion does
Eclairion is a French AI infrastructure company that designs, builds, and operates high-density data centers branded as "AI Factories" to host GPU compute clusters for artificial intelligence workloads. The company's core offering is the Space, Power, and Cooling (SPC) model — high-density colocation with rack densities exceeding 100 kW enabled by Direct Liquid Cooling (both direct-to-chip cold plate and immersion cooling), redundant high-availability power with direct national grid connection, and ISO 50001-certified energy management. It complements colocation with Infrastructure as a Service (IaaS) where Eclairion or partners operate GPU equipment on behalf of clients.
The company operates or is developing six sites across France: Bruyères-le-Châtel (120 MW, operational since 2025), Bessé-sur-Braye (335 MW), La Maxe (250 MW), Richemont (150 MW), plus EDF partnership sites at Bouchain (400 MW) and Loire-sur-Rhône (330 MW), totaling approximately 855 MW of planned capacity. All sites are brownfield redevelopments of former industrial assets (paper mills, EDF power plants) with existing grid connections, and the entire portfolio is operated under French and European law with exclusively French and European capital, supporting GDPR, NIS2, and SecNumCloud regulatory frameworks.
Eclairion sells to enterprise clients via direct field sales under multi-year contracts, targeting AI model publishers, large industrial groups, sovereign cloud operators, research laboratories, and GPU-as-a-service integrators. The company monetizes through recurring hosting fees based on power consumption and space utilization. Backed by a €2.5 billion committed investment and a $165.8M funding round from Tikehau Capital, Eclairion has assembled an ecosystem of partners including NVIDIA, Mistral AI, Schneider Electric, EDF, ENGIE, HPE, Dell, and others to position itself as the French sovereign alternative for AI compute infrastructure.

Revenue model
- High-Density Colocation: Eclairion provides space (high-density racks in secure buildings), electrical power (redundant high-availability supply with direct national grid connection), and cooling (advanced immersion and direct-to-chip systems). Clients bring their own GPU servers (NVIDIA H100, B200 or other architectures) and retain ownership and operational control of their hardware. Revenue derived from hosting fees based on power consumption and space utilization.
- Infrastructure as a Service (IaaS): GPU computing capacity provided without clients acquiring hardware themselves. Eclairion or partners operate equipment according to contractually defined performance and availability commitments. Revenue based on compute capacity rented to clients.

Product offeringCore offering
Eclairion designs and operates AI Factories providing high-density colocation under a Space, Power, Cooling (SPC) model, where clients bring their own GPU servers (e.g., NVIDIA H100, B200) and Eclairion supplies the racks, redundant power and Direct Liquid Cooling. The company also offers an Infrastructure as a Service (IaaS) option in which it or partners operate GPU equipment on behalf of clients, supported by a network of sovereign, geographically distributed sites across France.
Product overview
Éclairion operates as an AI Infrastructure Factory providing high-density colocation for AI computing. The core offering is the AI Factory platform offering space, power, and cooling (SPC model) with direct liquid cooling for rack densities exceeding 100 kW. The company complements this with Infrastructure as a Service (IaaS) options where Éclairion or partners operate GPU equipment on behalf of clients. A physical AI Infrastructure Factory Hub at Bruyères-le-Châtel serves as an innovation workspace. Éclairion's portfolio includes four operational/developmental sites: Bruyères-le-Châtel (120 MW, first operational 2025), Bessé-sur-Braye (335 MW), Richemont (150 MW), and La Maxe (250 MW), totaling 855 MW of planned capacity across France. The company positions itself as a physical-layer infrastructure provider; clients bring their own GPU servers (NVIDIA H100, B200, etc.) and retain full control of their stack.

Products and services
- AI Factory — High-Density Colocation (Space, Power, Cooling) Eclairion's core offering: high-density colocation under a Space, Power, Cooling (SPC) model for AI GPU clusters. Clients bring their own GPU servers (e.g., NVIDIA H100, B200) and install them in Eclairion racks at densities above 100 kW, while Eclairion supplies the secure building, redundant grid power and Direct Liquid Cooling (direct-to-chip and immersion). Targeted at AI model publishers, large industrial groups, sovereign cloud operators, research laboratories and GPU-as-a-service integrators with intensive AI compute needs.
- Infrastructure as a Service (IaaS) GPU computing capacity provided without clients acquiring hardware themselves. Eclairion or partners operate the equipment according to contractually defined performance and availability commitments, with revenue based on compute capacity rented to clients. Complements the SPC colocation offering for organizations that want managed infrastructure rather than owning their own servers.
- AI Infrastructure Factory Hub A 920 m² Grand Innovation Venue at Bruyères-le-Châtel designed to bring together the entire AI value chain in Île-de-France. Serves as workspace, experimentation centre and events venue for startups, industrial partners, competitiveness clusters (Cap Digital, Teratec) and research institutions operating within the Eclairion ecosystem.

Eclairion competitors and assessment
Company assessmentDirect peers
- OVHcloud: OVHcloud is the leading French and European cloud provider with its own data center infrastructure, including high-density and bare-metal GPU offerings. It competes with Eclairion for sovereign cloud and AI workloads under similar French/European positioning.
- Scaleway: Scaleway (Iliad Group) operates European sovereign cloud and bare-metal GPU infrastructure, including data centers in France. It targets similar AI and sovereignty-conscious customers as Eclairion.
- Data4: Data4 is a major French and European data center operator developing high-density and AI-ready campuses across France. It is a directly comparable colocation provider targeting similar enterprise and hyperscaler tenants.
Broad incumbents
- Digital Realty (Interxion): Digital Realty (which absorbed Interxion) operates the largest European colocation footprint with multiple Paris campuses. It competes broadly with Eclairion for enterprise and AI colocation demand but at much larger scale and broader geographic scope.
- Equinix: Equinix is the global leader in interconnection-focused colocation with multiple Paris IBX sites. It targets similar enterprise and cloud workloads but operates a much broader global portfolio rather than specializing in AI factory density.
Emerging players
- Nebius: Nebius is an AI-focused infrastructure builder operating GPU clusters and data centers with emphasis on high-density liquid-cooled deployments. It is a comparable emerging specialist in the AI infrastructure factory category.
- Crusoe Energy: Crusoe builds and operates AI data centers, originally pairing compute with stranded energy. It is a comparable emerging player focused on purpose-built AI infrastructure with sustainability and energy-efficiency themes similar to Eclairion.
- CoreWeave: CoreWeave is a hyperscale GPU cloud provider operating dedicated AI data centers with liquid cooling at scale. It is a comparable emerging specialist serving AI labs and large enterprise AI workloads with a similar business model.
Regional players
- Aruba Cloud (Aruba S.p.A.): Aruba operates European data centers and cloud services, primarily in Italy, with sovereign positioning for European customers. It is a comparable European colocation/cloud provider but does not directly compete in France.
Others
- Mistral AI: Mistral AI is a French AI model developer and anchor customer of Eclairion (10 MW deployment at Les Ulis plus financed capacity at Bruyères). It is an ecosystem/strategic partner rather than a colocation competitor, but its growth directly drives Eclairion's demand.
