Its flagship product, the Fedi mobile app, focuses on enabling scalable Bitcoin adoption while preserving user sovereignty and privacy.

Before joining Fedi, Obi was the CEO and co-founder of Coinfloor, one of the United Kingdom’s first Bitcoin-only exchanges, which he led for nearly eight years before its acquisition in 2021. Throughout his career, he has been a vocal advocate for financial freedom, open monetary systems, and broader global access to Bitcoin.

Crypto enthusiast and law student at the University of Lancashire, currently based in sunny Spain. A Web3 lawyer working in the proof-of-stake space — but with my heart firmly in proof of work. I have supported a wide range of real-world crypto and DeFi projects, but there is only one true benchmark for me: Bitcoin.
