Martin Köppelmann is CEO and co-founder of Gnosis, a decentralized blockchain and development group he has led since March 2017. Gnosis operates across multiple product lines including Gnosis Chain, Gnosis Pay, Safe, and CoW Swap. Köppelmann's current focus includes Circles v2, a community-owned money experiment that combines Metri wallet, Safe, CoW Swap, and Gnosis Chain into a single consumer application. The core mechanism of Circles allows anyone to create a "circle" that automatically mints one token per hour per member, with token value determined by community use.

Köppelmann co-founded Gnosis in January 2015 as part of ConsenSys, the blockchain development group led by Ethereum co-founder Joe Lubin. Gnosis was initially built as a prediction market platform on Ethereum. The project subsequently expanded into blockchain infrastructure, acquiring and merging with xDAI to create a privacy-focused side-chain for Ethereum. Gnosis Pay, a non-custodial payment card product, is currently available in Europe and Brazil, enabling users to spend cryptocurrencies via EURe, a euro-denominated stablecoin from Monerium, with USDC integration in development. Prior to Gnosis, Köppelmann built Fairlay, a Bitcoin-based prediction market, which he later sold. His interest in blockchain originated following the 2008 financial crisis and engagement with the German Pirate Party's "liquid democracy" concept. He studied IT Systems Engineering at the Hasso Plattner Institute in Potsdam, completing a Bachelor's degree from 2007 to 2010 and an advanced degree from 2010 to 2013.
