French Quantum Computing Startup Quobly Raises €115 Million In Series A Round

The round was led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom. Existing shareholders also include the CEA, CNRS, Quantonation, and Supernova Invest.

Following its seed stage, during which it developed its silicon-qubit technology and integrated hardware-software architecture, Quobly is now focused on scaling production and bringing its quantum systems to market.

The company’s technology is based on FD-SOI semiconductor processes manufactured on 300 mm wafers, allowing it to leverage existing semiconductor industry infrastructure while addressing key challenges around scalability, reproducibility and manufacturing yield.

Quobly plans to launch Alloy Pioneer, the first system in its Alloy product family, through the cloud in 2026 via Alloy Forge, its quantum application development platform. The system is expected to be deployed in high-performance computing (HPC) environments in 2027.

Designed to integrate with existing data centres and HPC infrastructure Quobly’s quantum computers aim to provide a practical path toward large-scale quantum computing using established semiconductor manufacturing techniques.

The new funding will support the development of more powerful and scalable silicon quantum processors, advance manufacturing capabilities and accelerate the deployment of the company’s first commercial quantum computing systems.

Maud Vinet, CEO and co-founder of Quobly, said the financing marks a transition from technology validation to industrial deployment: With this Series A, we are accelerating the deployment of our first commercial systems and building a quantum computing platform designed to integrate into existing computing infrastructures. Our objective is to make quantum computing deployable, scalable and usable within real industrial environments.
