Recipients include Refute, a disinformation detection and response platform supporting governments and enterprises to counter coordinated disinformation campaigns; Ploy, an agentic-powered identity governance and administration platform; and Aviel, a threat intelligence platform that gathers actionable data on online fraud activities targeting consumers.
The fund continues to be supported by a cornerstone commitment from the British Business Bank through its Enterprise Capital Funds (ECF) programme, and is accredited by the UK’s National Security Strategic Investment Fund (NSSIF).
Existing investors have been joined at final close by Imperial College London’s Endowment and Planet First Partners, alongside further commitments from exited UK cyber entrepreneurs and senior leaders from across the cyber and national security communities.
