CyLon

CyLon Ventures invests in early-stage companies advancing security and resilience technologies. The firm deploys its own angel-sized capital, combined with specialized sector expertise and a valuable network. This supports founders in securing initial customers, building partnerships, and attracting further investment for innovations spanning identity management, threat intelligence, and cyber skills.

Established in 2015, CyLon Ventures was co-founded by Grace Cassy, Jonathan Luff, and Alex van Someren. Their core insight: security forms the essential layer for all future innovation. Cassy and Luff brought extensive national security and technology backgrounds. Van Someren, a former Chief Scientific Advisor, also achieved entrepreneurial success co-founding nCipher, an internet security company with a major IPO.

The firm partners with founders of emerging security and resilience startups. CyLon Ventures' vision prioritizes deep founder alignment, harmonizing strategic support and investment timelines with portfolio needs. They aim to cultivate robust security foundations, enabling transformative innovations across diverse sectors, and shaping a future where inherent security drives progress.
