Exaion

What Exaion does

Exaion is a French high-performance private cloud infrastructure provider, headquartered in Neuilly-sur-Seine and founded in 2020, that delivers dedicated HPC and AI infrastructure to enterprises with sensitive data and regulatory requirements. Its platform is built on a 100% open-source foundation (OpenStack for IaaS, Kubernetes for PaaS) running across four data centers in Europe and North America, with 1,250 GPUs, 37 PB of storage, 99.9% availability, and 24/7 L2/L3 support. Core products include Exaion Compute (custom HPC cloud with bare-metal options and on-premises deployment), an Enterprise AI PaaS for running LLMs, vision models and agents with RAG and fine-tuning, Exaion Studio for 3D rendering and workstations, plus specialized security and data-sanitization tools (Exaion Gateway, Exaion Wipe) and a blockchain services suite (Institutional Custody Vault, Delegated Staking, Validator- and Node-as-a-Service). The company differentiates on data sovereignty, immersion cooling and refurbished TOP500-class hardware for sustainability, and certified security (DoD 5220.22-M, ISO/IEC 27040:2015, AMF DSAP).

The business model is enterprise sales-led with quote-based, subscription and managed-services pricing billed monthly, targeting vertical markets including media and entertainment, financial services, industrial, automotive, energy, and architecture/engineering/construction. Distribution is primarily direct enterprise field sales, complemented by channel partnerships with BNP Paribas, SG Forge, EY, and the parent-company network of MARA Holdings (which acquired a 64% majority stake for approximately $168 million in February 2026, with EDF Pulse Ventures retaining a minority interest and remaining a customer, and NJJ Capital acquiring a 10% stake in MARA France as a condition of regulatory approval). The go-to-market emphasizes sovereign-cloud positioning for regulated EU industries, a partner ecosystem anchored by Nvidia, EDF, and Quandela, and infrastructure expansion via the Starwood Digital Ventures joint venture targeting more than 1 gigawatt of HPC and AI capacity.
