Founded in the UK, OQC develops and operates superconducting quantum computers designed for deployment in data-centre environments serving enterprise and government customers. The company has established a global quantum computing platform across Europe, North America and Asia, with systems deployed in the UK, US, Japan and Spain.

Enterprise and government customers across financial services, defence and security are driving demand for OQC’s systems as they seek secure, scalable quantum infrastructure to tackle problems beyond the practical reach of classical computing. The funding will be used to expand OQC’s operational presence in priority markets and accelerate its roadmap toward commercially useful, fault-tolerant quantum computing.

“This is a coming-of-age moment for British quantum computing. It shows that British companies can play a leading role in a technology that will shape all our futures. Globally, it represents a clear shift in the market – from long-term promise to near-term delivery in quantum computing. For OQC, this gives us the capital to scale internationally, advance our technology roadmap, and meet increasing demand from customers seeking secure, scalable access to quantum computing infrastructure,” said Gerald Mullally, CEO of OQC.

“After looking at a deluge of humanoid robotics companies, my fellow Partner, Alon Kuperman, and I were delighted to meet Ralf and Marc, who have built an AI operating system that seamlessly retrofits into the world’s vast fleet of industrial robots already in action,” said Per Roman, Founding Partner of Bullhound Capital.

Bullhound Capital led the round, which included investment from the British Business Bank, Fynveur (advised by Invus), COFIDES, RCM Private Markets Fund managed by Rokos Capital Management (US) LP, Alpha Edison, Fulcrum Asset Management, Pentland Ventures, Magdalen College Oxford, Adaptive Capital Partners, Firgun Ventures, 18 West and Oxford Capital. Existing investors including Oxford Science Enterprises, SBI, Chevron Technology Ventures, The University of Tokyo Edge Capital Partners Co. and OTIF Ventures also participated, reflecting continued support for OQC’s technology roadmap and international expansion. J.P. Morgan acted as exclusive placement agent on the transaction.
