Christopher Grilhault des Fontaines
Co-founder & COO of Dfns
Since 2010, I’ve co-founded 4 companies, raised $10M, hired +40 employees, pioneered an SSE-based alt venue in France (Aion, a cooperative organizing 250 free concerts per year, selling 100% organic & fair trade food, ranked 1 of 334 in South-West of France on TripAdvisor), built a professional network for entrepreneurs with a community of 30k+ users (Jollyclick) and a professional networking app (Purpl) ranking me #182 among the Top Networking App Founders on Crunchbase in 2020. 

Presently, I’m the co-founder & CGO of Dfns (Techstars ’21), a dev tool providing custody as a service for cryptocurrencies. Blockchain is changing finance much like internet changed communication—forever. It’s an eye-opening technology that is revolutionizing the way we trade and transfer money as worldwide transactions become cheaper, faster, more open and more reliable. However, blockchain has one Achilles heel we call the private key. More than $200 billion worth of bitcoin have already been lost, and in almost all cases, the losses were caused by private key theft or misuse. Today, I’m on a mission to deliver inner peace to crypto. Dfns provides a safe, cloud-native API that gives banks, investors and companies the freedom to enter crypto markets on a battle-designed security infrastructure. We are building the future of crypto banking, brick by brick. HMU on Twitter @christophergdf or email me [email protected]
