Quobly funding, valuation and investors

Overview

Quobly is a Grenoble-based quantum computing company founded in 2022 by Maud Vinet (CEO, ex-Intel quantum lead) and Tristan Meunier (CSO, quantum engineering expert). The company develops silicon spin qubits using fully depleted silicon-on-insulator (FD-SOI) technology on 300mm wafers—leveraging existing semiconductor manufacturing rather than bespoke quantum fabs. Quobly co-designs chips with STMicroelectronics and targets rack-scale "Alloy" quantum computers deployable in data centers for chemistry, materials, optimization, and logistics workloads. After a €19M seed (2023) and follow-on programs including Q100T, Quobly raised €115M Series A in June 2026 led by Bpifrance, STMicroelectronics, and SEALSQ to industrialize processors and ship a first commercial product by end-2026. The company employs 100+ people with offices in France, Singapore, and Canada.

Why Quobly is interesting

Quantum winners may be decided by fab compatibility, not lab qubit counts alone. Quobly's STMicroelectronics partnership and €115M Series A bet that FD-SOI silicon can reach commercial systems faster than exotic-material approaches.

Product & use cases

Quobly builds silicon-based quantum processors and integrated control/software stacks (QSOI platform) manufactured on STMicroelectronics' high-volume lines. Alloy-branded systems are designed as rack-scale machines that slot into data-center environments rather than laboratory prototypes.

• Computational chemistry and materials simulation for industrial R&D
• Optimization problems in logistics and supply-chain planning
• Hybrid HPC + quantum workflows in enterprise data centers
• Sovereign European quantum capacity for government and enterprise buyers

Key facts

• Series A (Jun 2026): €115M led by Bpifrance, STMicroelectronics, and SEALSQ
• Seed (2023): €19M—record European quantum-hardware seed at the time
• Strategic manufacturing partnership with STMicroelectronics on 300mm FD-SOI
• Roadmap targets million-qubit systems by 2032 for data-center deployment
• 100+ employees; offices in Grenoble, Singapore, and Canada
• Alloy product line: rack-scale quantum computers for existing infrastructure

Funding history (newest first)

Competitive landscape

Edge: Industrial silicon manufacturing path—same 300mm ecosystem that produces billions of classical chips—potentially compressing cost and reproducibility versus superconducting or trapped-ion bespoke fabs.

European quantum funding increasingly rewards manufacturability and supply-chain leverage, not qubit headlines alone. Quobly must prove yield, error correction, and customer value on Alloy systems while capital-intensive peers with different physics paths race the same commercial window.

• Oxford Quantum Circuits direct

  European quantum hardware peer; different qubit architecture but similar commercialization race.

• IQM direct

  Finnish superconducting quantum computers; Quobly bets on silicon CMOS compatibility instead.

• Intel (silicon spin qubits) adjacent

  Major corporate silicon-qubit program; Quobly's founders have deep Intel quantum lineage.

• Pasqal direct

  French quantum competitor using neutral-atom approach rather than silicon spins.

Notable stories

• Quobly's €19M seed in 2023 was reported as a record European seed for quantum hardware, building on 15+ years of CEA-Leti and CNRS collaborative research (Quobly press release).
• CSO Tristan Meunier presented a roadmap targeting millions of qubits by 2032 using industrial FD-SOI processes at APS March Meeting 2026 (Datacenter News).
