CyLon was founded to support the security technologies of the future
We believe that security is the enabling layer for innovation. From autonomous driving to digital healthcare and smart energy systems, no future technology will reach its full potential without secure foundations.
Until 2020, we ran best-in-class cyber security accelerator programmes across the world, operating on the ground in Europe, Asia and the Middle East, in partnership with governments and corporates. The companies we accelerated are now valued collectively at more than £1bn.
We now focus exclusively on investing in a small number of top quality startups. We have always defined cyber security broadly, and so support companies building a wide range of high-impact technologies, from cyber skills training to identity management to threat intelligence.
CyLon was founded by a trio of security experts: Grace Cassy, Jonathan Luff and Alex van Someren.
Collectively, Grace and Jonathan have more than 30 years of experience across national security policy, technology and investment. They began their careers in the UK Diplomatic Service, with Grace serving as an advisor to Prime Minister Tony Blair and Jonathan as an advisor to Prime Minister David Cameron.
They also co-founded Epsilon Advisory Partners, a strategy and growth firm which works with world-leading global technology companies and investors.
Alex is the UK Government’s Chief Scientific Advisor for National Security.
In 1996 Alex co-founded nCipher with venture capital backing to develop internet security products using advanced cryptography, and led the company to a £350m IPO on the London Stock Exchange. He was then Managing Partner of the Early Stage Funds at Amadeus Capital Partners until 2021.
