Summary
Osney Capital, a London-based venture capital firm specializing exclusively in early-stage cybersecurity, announced the final close of its debut fund at €69 million (£60 million) on an oversubscribed basis, exceeding its initial hard cap target. The firm, founded in 2020 and led by founding partners Adam Cragg, Joshua Walter, and Paul Wilkes, has positioned itself as the UK's first sector-specialist venture capital seed fund dedicated entirely to the early-stage cyber sector.

The fund received substantial institutional backing, with the British Business Bank committing up to £36 million as a cornerstone investor through its Enterprise Capital Funds (ECF) programme. At final close, the investor base was expanded to include Imperial College London's Endowment and Planet First Partners, both adding meaningful capital commitments. The fund's accreditation by the UK's National Security Strategic Investment Fund (NSSIF) underscores its strategic significance to the broader UK cyber ecosystem and national security objectives.

Joshua Walter, founding partner at Osney Capital, characterized the oversubscribed close in the current market environment as validation of investor appetite for specialist early-stage cyber capital. He noted that the strong fundraising result reflects investor recognition that the UK's cybersecurity sector represents "one of the most exciting early-stage opportunities globally" and benefits from on-the-ground specialist investment support. Imperial College London's Chief Investment Officer John Anderson echoed this perspective, highlighting cybersecurity's growing importance to UK economic and strategic interests, and emphasizing that the endowment's investment provides exposure to homegrown innovations with potential to become significant commercial successes.

Osney Capital will deploy capital into early-stage cybersecurity companies through check sizes ranging from £250,000 to £2.5 million per investment. The firm's specialist focus and experienced management team are designed to support UK cyber founders during critical early growth stages, positioning them to scale into potential category leaders. The successful close reflects broader momentum in the UK's cyber talent development and validates the case for dedicated seed-stage venture capital focused on this strategically important sector.
