UK-based Osney Capital Launches Cybersecurity Seed Fund, Surpassing €58 Mn Target

The fund is backed by the British Business Bank and accredited by the UK’s National Security Strategic Investment Fund (NSSIF). It also has support from institutional and private investors like IronGate Capital Advisors, East X Ventures, and several successful UK cyber entrepreneurs and national security experts.

Joshua Walter, Partner of Osney Capital, said: “The UK’s cyber ecosystem is one of the country’s greatest untapped strengths. With world-class talent and the scale to produce the next generation of industry leaders, we have a unique opportunity to compete on the global stage. Our mission with this Fund is to identify and back the next wave of UK cyber founders – providing them with the specialist capital they need to build globally significant companies, products and technologies.”

Christine Hockley, Managing Director and Co-Head of Funds at the British Business Bank, added: “We are pleased to make this commitment to Osney Capital’s Fund I, which aligns with our objective of supporting promising companies to access the long-term investment they need to fulfil their growth potential. Cyber resilience lies at the heart of the UK’s role as a responsible cyber power.

“Our commitment to Osney Capital will capitalise on the strong investment opportunity offered by growing UK companies within the sector while also building the UK’s national resilience.”

Dame Fiona Murray DCMG CBE, who serves on the UK Prime Minister’s Council for Science and Technology and Vice-Chair of the Board of Directors of the NATO Innovation Fund, said: “Science and technology are essential to national competitiveness and increasingly, our competitiveness is grounded in national security. Osney Capital’s Fund is an opportunity for the UK to build on the UK’s strong advantage and excellence in cyber security.

“In times of global uncertainty, we must foster a safe, secure and trusted digital economy in the UK – across all our digital and physical infrastructure. This means investing in and promoting innovation in the UK’s cyber security ecosystem. The work of Osney Capital’s Fund is a matter of national security, digital sovereignty, and economic leadership.”
