Challenges estimated Eric Larchevêque's professional wealth at about €340 million in 2024, ranking him 392nd among French fortunes. He is a co-founder of Ledger and a strategic shareholder.
His first exit came in 2007, when he sold Montorgueil, the dating and entertainment firm he founded in 1998, for about €22 million. He then played poker professionally until 2009. In 2011 he created Prixing, a grocery price-comparison service, and sold it to HighCo in 2014.
In 2014 he opened La Maison du Bitcoin in Paris and co-founded Ledger, which makes hardware wallets for crypto keys. Ledger raised $75 million in 2018. In May 2019 he handed management to Pascal Gauthier and became chairman.
Ledger passed a $1.5 billion valuation in 2021. In 2025 co-founder David Balland was kidnapped, and Larchevêque campaigned for firearms permits for crypto professionals. That year he also joined investors who took over the listed company that became The Bitcoin Society, renamed on 24 November 2025.
