CyLon Ventures

CyLon Ventures are Europe's leading specialist early stage investors in security and resilience. They are not a VC fund; they invest using their own capital to stay founder aligned, with angel-sized cheques. Their team combines national security experience with nearly a decade working with founders of enterprise security startups, and they focus on helping portfolio companies reach early customers, meet investors, and build strategic relationships.
