— HOW WE HELP

Our brilliant portfolio Founders leverage our unique network and sector expertise, benefiting from everything we’ve learned about what it takes to achieve escape velocity in this uniquely challenging sector.

We focus on supporting our portfolio to reach early customers, meet other investors, and build long-term key strategic relationships.



— WHY US?

Our team has deep expertise in this sector, combining national security experience with nearly a decade working with the founders of enterprise security startups.

We were the first investors in companies like Immersive Labs, Tessian, and some of the most exciting young companies in the UK, US and Israel.

OUR PORTFOLIO

— HOW WE WORK

CyLon Ventures is not a VC fund. Instead, we invest using our own capital to allow us to be uniquely founder aligned, thanks to it being our own skin in the game. Our timeline is your timeline, and your priorities are our priorities.

Our cheques are therefore ‘angel-sized’. Whether you’re raising now or not, if you’re in the early phases of building one of the security technologies of the future then we’d love to hear from you.
