About Quobly
Quobly is a Grenoble quantum-computing company founded in 2022 as a CEA-Leti and CNRS spin-off by CEO Maud Vinet, CTO Tristan Meunier and COO François Perruchot. It builds silicon spin-qubit quantum computers on FD-SOI semiconductor processes (300 mm wafers) so qubits can be manufactured with industrial fabs rather than exotic materials, targeting cloud and HPC deployment under its Alloy product line (Alloy Pioneer via Alloy Forge). Strategic partners include STMicroelectronics, Air Liquide, Soitec and Orano. After a €19 million seed phase (2023–2025), Quobly closed a €115 million Series A in June 2026 led by Bpifrance, SEALSQ and STMicroelectronics, with the EIC Fund, Blast, ALIAD (Air Liquide Venture Capital) and Innovacom, and existing CEA, CNRS, Quantonation and Supernova Invest, to industrialise processors and launch the first commercial Alloy systems by end-2026.
