QUOBLY raises €115 million and reaffirms its industrial independence strategy

A few months after entering exclusive negotiations with SEALSQ regarding a potential majority investment, Grenoble-based quantum computing startup Quobly has announced a €115 million Series A financing round led by Bpifrance, SEALSQ, and STMicroelectronics. The funding enables the company to maintain its independence while accelerating the industrialisation of its silicon-based quantum computers.

The transaction represents a significant milestone for the French quantum ecosystem. In January, SEALSQ announced the signing of a Memorandum of Understanding that could have led to an investment of up to $200 million and potentially resulted in a majority stake in Quobly. At the time, the announcement raised questions about the future of one of Europe’s most prominent quantum computing startups.

Six months later, the outcome looks markedly different.

According to our information, one of the key reasons behind this evolution was Quobly’s determination to continue developing its own industrial and technological ecosystem. Rather than pursuing integration into a single corporate structure, the company opted for a path that would allow it to bring together a broad network of industrial, technological, and financial partners around its platform.

This strategy is reflected in the composition of the new financing round. Alongside SEALSQ are Bpifrance, through its Deep Tech 2030 fund, STMicroelectronics, the EIC Fund, ALIAD, the venture investment arm of Air Liquide, Blast, and Innovacom. Existing sfrancehareholders, including the CEA, CNRS, Quantonation, and Supernova Invest, also remain on board.

Far from representing a strategic shift, this fundraising round follows the trajectory outlined several months ago by Quobly co-founder and CEO Maud Vinet. As early as November 2025, she indicated during an interview with FW.MEDIA that the company was preparing a financing round of approximately €100 million to support the industrialisation of its technology and its commercial deployment. The final amount raised ultimately exceeded those initial expectations.

Today, Quobly’s challenge is no longer to demonstrate the scientific feasibility of its approach. Since its founding in 2022, the company has focused on developing silicon qubits compatible with manufacturing processes already used throughout the semiconductor industry. Following nearly €40 million in seed financing between 2023 and 2025, Quobly believes it has validated the key technological building blocks required to manufacture its quantum processors.

The next phase is about transforming scientific progress into industrial capability.

In France, Quobly operates alongside Alice & Bob, which recently raised €100 million, and Pasqal, backed by more than €340 million in financing. The three companies represent distinct technological approaches to quantum computing. While Alice & Bob focuses on superconducting cat qubits and Pasqal develops neutral-atom quantum processors, Quobly is betting on silicon qubits designed to be manufactured using existing semiconductor production processes. Internationally, this strategy places the Grenoble-based company closer to players such as Quantum Motion, Diraq, and Silicon Quantum Computing, all of which are seeking to leverage existing semiconductor manufacturing infrastructure to solve one of the industry’s greatest challenges: industrial-scale production.

This industrial focus explains the growing presence of strategic corporate investors in Quobly’s capital structure. Beyond their financial contribution, STMicroelectronics, Air Liquide, Soitec, and Orano are helping build the value chain required to address manufacturing yields, process control, cryogenics, and large-scale production areas that will ultimately determine the future viability of quantum computing.

The company’s immediate objective is to commercialise its first cloud-accessible quantum computer by the end of 2026 under the Alloy brand. Named Alloy Pioneer, the system is aimed initially at high-performance computing and research users before broader deployment into HPC environments beginning in 2027.

Beyond the financing itself, the transaction illustrates the broader evolution of the European quantum sector. For years, investment was concentrated on fundamental research and proving the viability of competing quantum architectures. The conversation is now shifting toward industrialisation. Manufacturing yields, standardisation, integration into existing computing infrastructure, and the ability to scale production are increasingly becoming as important as scientific performance.

Viewed through this lens, Quobly’s fundraising sends a powerful signal. The company is positioning itself not merely as a developer of quantum technologies, but as a platform around which a complete industrial ecosystem can be built. By remaining independent, Quobly seeks to preserve a central role in the emergence of a European quantum computing industry.

For public institutions such as Bpifrance, as well as the industrial groups participating in the round, the stakes now extend well beyond a single startup. The objective is to establish European design and manufacturing capabilities in a field increasingly viewed as strategic for the future of computing infrastructure, cybersecurity, and artificial intelligence.

With more than 100 employees, operations in Grenoble, Singapore, and Canada, and a growing network of industrial partnerships, Quobly now has the financial resources required to tackle what is often the most difficult stage for any deeptech company: transforming a technological breakthrough into a commercially viable industrial product.
