A few months after opening exclusive negotiations with SEALSQ with a view to acquiring a majority stake, the Grenoble startup Quobly finally announces a fundraising of 115 million euros led by Bpifrance, SEALSQ and STMicroelectronics. A financing round that allows the company to maintain its independence while accelerating the industrialization of its silicon quantum computers.
The operation marks an important step for the French quantum ecosystem. Last January, SEALSQ announced the signing of a Memorandum of Understanding paving the way for an investment of up to $200 million and potentially leading to a majority takeover of Quobly. At the time, the announcement raised many questions about the future of one of the main European quantum computing startups.
Six months later, the scenario chosen is significantly different.
According to our information, one of the reasons leading to this development is Quobly’s desire to continue the development of its own industrial and technological ecosystem. Rather than following a logic of integration within a single player, the company has favored a trajectory allowing it to bring together a set of industrial, technological and financial partners around its technology.
This orientation appears today in the very composition of the roundtable. Alongside SEALSQ are now Bpifrance, via the Deep Tech 2030 fund, STMicroelectronics, the EIC Fund, ALIAD, the Air Liquide investment vehicle, Blast as well as Innovacom. The historic shareholders, including the CEA, the CNRS, Quantonation and Supernova Invest, also remain present.
This lifting does not constitute a change of strategic course. On the contrary, it is part of the trajectory mentioned for several months by Maud Vinet, co-founder and general director of Quobly. As early as November 2025, the manager indicated on the FW.MEDIA set that she was preparing a financing operation of around 100 million euros intended to support the industrialization of the technology and its commercial deployment. The amount finally obtained is even higher than the objectives initially mentioned.
The challenge for Quobly today is no longer to demonstrate the scientific feasibility of its approach. Since its founding in 2022, the company has focused its efforts on developing silicon qubits compatible with industrial processes used by the semiconductor industry. After a seed phase totaling nearly 40 million euros between 2023 and 2025, the company estimates that it has validated the main technological barriers necessary for the manufacture of its quantum processors.
The new step now consists of transforming this scientific advance into industrial capacity.
In France, Quobly is operating alongside Alice & Bob (which has also just raised 100 million euros) and Pasqal (which benefits from 340 million euros in funding), three companies which embody distinct technological approaches to quantum computing. Where Alice & Bob relies on superconducting qubits and Pasqal on neutral atoms, Quobly develops silicon qubits designed to be produced using industrial processes already used by the semiconductor industry. On an international scale, this strategy brings the Grenoble-based company closer to players like Quantum Motion, Diraq and Silicon Quantum Computing, who also seek to take advantage of existing manufacturing infrastructures to solve one of the main challenges of the sector: the transition to industrial scale.
This strategy explains the growing presence of industrial players in the company’s capital. Beyond their financial role, STMicroelectronics, Air Liquide, Soitec and Orano are participating in the construction of a value chain intended to resolve the challenges of manufacturing, process control, cryogenics and scaling up which will condition the future of quantum computing.
The stated objective is now to market a first quantum computer accessible in the cloud by the end of 2026 under the Alloy brand. Called Alloy Pioneer, this system targets users of high-performance computing and scientific research before wider deployment in HPC infrastructures from 2027.
Beyond financing, this operation also reflects the evolution of European quantum computing. For several years, investments mainly focused on fundamental research and the validation of technological architectures. The subject now becomes industrial. Questions of manufacturing efficiency, standardization, integration in computing centers and capacity to produce on a large scale are gradually taking precedence over scientific performance alone.
In this perspective, the lifting of Quobly appears to be an important signal. The company is no longer positioning itself only as a developer of quantum technologies, but as an actor seeking to unite a complete industrial ecosystem around itself and maintain a central role in the construction of a European quantum computing sector.
For the public authorities, notably BPIfrance, as well as for the industrialists involved in the operation, the issue now goes beyond the framework of a startup. The aim is to create a European design and production capacity in an area considered strategic for future computing, cybersecurity and artificial intelligence infrastructures.
With more than 100 employees, locations in Grenoble, Singapore and Canada, as well as leading industrial partnerships, Quobly now has the financial means necessary to attempt to take the most difficult step for any deeptech company: transforming a technological promise into an industrial product that can be marketed on a large scale.
