Founded: 2022
Headquarters: Grenoble, France
Team size: 101-500
Total funding: $147.4M

Value proposition

Industrial-scale quantum computing built on proven semiconductor manufacturing (FD-SOI on 300mm wafers), enabling million-qubit chips at lower cost by leveraging existing semiconductor infrastructure and amortized Capex.

Products and solutions

Alloy Pioneer (first commercial quantum computer, cloud-accessible by end of 2026, HPC deployment in 2027), Alloy Forge (development environment for quantum applications), Silicon spin qubit quantum processors on 300mm FD-SOI wafers, Rack-scale quantum computers for data center deployment

Unique value

Only quantum computing company using standard FD-SOI semiconductor processes on 300mm wafers to manufacture silicon spin qubits, enabling integration of 1M qubits and control electronics in a coin-sized chip fitting in 3 data center racks.

Target customer

Enterprises in chemistry, material science, optimization, and logistics; high-performance computing (HPC) data centers; government research programs (Proqcima)

Industries served

Chemistry, Material Science, Optimization, Logistics, High-Performance Computing, Cybersecurity

Technology advantage

Silicon spin qubits on 300mm FD-SOI wafers; single-qubit gate fidelities approaching 99.999% using isotopically enriched 28Si substrates; 65+ patents filed; strategic partnership with STMicroelectronics for industrial fabrication; integration with Soitec for 28Si FD-SOI substrates; spin-off from CEA-Leti and CNRS with 15+ years of prior research

How they differentiate

Unlike competitors pursuing exotic qubit architectures (superconducting, trapped ions, photonics, neutral atoms), Quobly leverages mature semiconductor FD-SOI manufacturing processes already proven at scale, enabling faster industrialization, lower costs, and seamless integration with existing data center infrastructure.

Main competitors

Pasqal (France, neutral-atom quantum computing), IQM (Finland, superconducting quantum computers), Quantum Motion (UK, silicon qubits), PsiQuantum (US, photonic quantum computing)

Key partnerships

STMicroelectronics (strategic partnership for industrial quantum processor manufacturing on 300mm fab line), CEA-Leti (R&D and pilot line), CNRS (research), Soitec (28Si FD-SOI substrates), TNO (industrialization collaboration), Air Liquide (semiconductor-grade capabilities), Entropica Labs (MoU for fault-tolerant quantum computing in Singapore), Hon Hai Research Institute / Foxconn (open-source QPE Toolbox), National Quantum Federated Foundry (NQFF) Singapore

Notable customers

Proqcima programme (French government €500M quantum initiative — selected as one of five companies), €10M in revenues from Proqcima in 2025-2026

Major milestones

2022: Company founded as spin-off from CEA-Leti and CNRS, 2023: €19M Seed round (largest seed for a European quantum company), Dec 2025: First 28Si FD-SOI wafers from Soitec cycling in STMicroelectronics' 300mm fab, Oct 2025: Incorporated in Singapore for Asia expansion, Jan 2026: Opened Canadian subsidiary in Sherbrooke, Quebec, Feb 2026: MoU with Entropica Labs in Singapore, Jun 2026: €115M Series A led by Bpifrance, SEALSQ, STMicroelectronics, End of 2026: Planned launch of first cloud-accessible quantum computer (Alloy Pioneer)

Growth metrics

90+ employees; 65+ patents filed; 4 global locations (France, Singapore, Canada, US); €10M revenue (2025-2026, primarily from Proqcima programme)

Market positioning

One of five companies selected for France's €500M Proqcima quantum program; positioned as the leading silicon-based (spin qubit) quantum computing company in Europe; competing in the global race for fault-tolerant quantum computing alongside Pasqal, IQM, and PsiQuantum

Geographic focus

France (HQ, R&D); Europe (primary market); Singapore (Asia-Pacific hub, incorporated Oct 2025); Canada (subsidiary in Sherbrooke, opened Jan 2026); North America expansion

Patents and IP

65+ patents filed (as stated on company website)
