The firm had initially targeted £50 million but exceeded that threshold, signaling strong institutional appetite for early-stage cyber investing in the UK market. This achievement positions the fund among the largest first-time seed vehicles in the UK focused exclusively on cybersecurity startups.
The fund's deployment strategy centers on backing approximately 30 companies at the pre-seed and seed stages, with ticket sizes ranging from £250,000 to £2.5 million. Osney Capital has signaled its willingness to follow investments through Series A rounds, providing extended support to founders as they scale. This multi-stage approach reflects a strategic commitment to nurturing the UK's next generation of cyber founders during critical growth phases.
The capital base reflects meaningful institutional support. The British Business Bank, operating through its Enterprise Capital Funds programme, is a cornerstone investor, with Managing Director and Co-Head of Funds Christine Hockley commenting that the commitment "aligns with our objective of supporting promising companies to access the long-term investment they need to fulfil their growth potential." Additional backing comes from institutional investors IronGate Capital Advisors and East X Ventures, alongside capital from successful UK cyber entrepreneurs and senior figures in the national security sector. The fund has also secured accreditation under the UK's National Security Strategic Investment Fund, underscoring government alignment.
