What Qarnot does
Qarnot Computing SAS, founded in 2010 and headquartered in Montrouge, France, operates a sovereign European cloud HPC platform targeted at engineers and R&D teams that need on-demand high-performance computing for numerical simulation without managing their own data centers. The platform supports CAE workloads such as CFD, structural analysis, multi-node MPI physics codes, and pre-configured engineering software (ANSYS Fluent, Abaqus, Star-CCM+, OpenFOAM, MATLAB Simulink, CONVERGE), with SDKs in Python, C#, and Node.js enabling CI/CD integration and automated campaign management.
The underlying infrastructure is the company's principal technical differentiator: distributed data centers built on OCP-compliant hardware with AMD EPYC processors, RoCE networking delivering approximately two-microsecond MPI latency, containerized Docker workloads, and the patented QBx computing cluster whose waste heat is directly recovered for building heating. This produces a PUE of 1.01 and up to 80% CO2 reduction on customer simulations versus conventional cloud, a claim validated by deployments such as MaiaSpace (16 tons CO2 saved, 82.3% reduction) and Gauss Fusion. The stack is secured with ISO 27001 and HDS certifications, with ANSSI SecNumCloud qualification in progress.
Revenue is generated through a three-tier usage-based model (Flex interruptible, On-Demand, and Reserved capacity contracts) plus a BYOL software catalog, distributed via self-serve PLG, direct enterprise sales, and channel partners (Dynas+, Simvia, pSeven, Kitware). Customer base spans aerospace (MaiaSpace, Dark, Aura Aero), energy and fusion (Gauss Fusion), CFD engineering consultancies (Nemosflow), and automotive, with a dedicated startup program. Growth is supported by public funding sources including EIC Accelerator, Bpifrance, ADEME, and France 2030, and by ecosystem positioning through the CLUSSTER sovereign cloud consortium.

Qarnot competitors and assessment
Company assessmentEmerging players
- SimScale: Cloud CAE simulation platform (CFD, FEA, thermal) targeting engineers. Overlaps with Qarnot on engineering user base and simulation workloads, though SimScale is a SaaS front-end vs. Qarnot's raw HPC infrastructure.
- Lambda: GPU cloud and workstation provider focused on AI and HPC. Comparable cluster-based compute and high-performance networking, but primarily AI-skewed rather than CAE engineering.
- Crusoe Energy: Cloud provider built around stranded/clean energy with a sustainability differentiation similar to Qarnot's heat-recovery narrative. Comparable in energy-resource efficiency positioning, though focused on AI/GPU compute.
- CoreWeave: Specialized GPU cloud provider serving AI and HPC workloads. Comparable in providing cluster-oriented compute with high-performance networking (InfiniBand/RoCE), but skewed toward AI/GPU rather than CAE.
Direct peers
- Scaleway: European cloud provider (Iliad group) offering bare-metal, instances, and HPC/GPU products with EU sovereignty focus. Direct competitor for sovereign cloud HPC workloads among French and European customers.
- OVHcloud: French/European hyperscale cloud provider offering IaaS, bare metal, and HPC instances with European data sovereignty positioning. Direct competitor in the EU sovereign cloud HPC market, with broader scale and product portfolio.
- Rescale: Cloud HPC platform purpose-built for engineering and scientific simulations (CFD, FEA, CAE). Closely comparable business model: cloud HPC for engineers, software catalog (Ansys, OpenFOAM), multi-tier usage-based pricing.
Broad incumbents
- Hetzner Cloud: European cloud provider known for cost-efficient dedicated servers and cloud instances. Competes on price-performance for European compute workloads; broader portfolio but less HPC-specialized.
- Nimbix (now part of Ansys/Atos): Historically a cloud HPC platform purpose-built for Ansys and engineering workloads. Closely comparable in CAE HPC focus; now embedded within larger simulation software ecosystem.
Regional players
- GENCI (French National HPC): French public HPC organization operating national supercomputers (IDRIS/TGCC) for academic research. Adjacent as a French HPC provider for scientific compute, but a public/academic peer rather than commercial cloud.
