Jean Meyer is Co-Founder and CEO of Deblock, a French crypto-banking platform that combines a non-custodial crypto wallet with a traditional bank account. He co-founded the company in October 2022 and leads both product and overall strategy. Deblock has raised a total of €56 million since founding, including a €30 million Series A in November 2025 led by Speedinvest, with participation from CommerzVentures, Latitude, 20VC, Headline, Chalfen Ventures, and Kraken Ventures. The Series A will fund product development — including collateral requirements for card programs and new liquidity-dependent products — as well as marketing and geographic expansion, beginning with a planned launch in Germany and Austria in Q1 2026. Meyer has stated that Deblock built its entire technical infrastructure in-house, including KYC, core banking, and payment rails, a process that took two years of development.

Prior to founding Deblock, Meyer was Head of Crypto at Revolut, a role he held from September 2021 to April 2022. Before Revolut, he founded Wanted, a talent compensation platform that was acquired by Revolut, and Once Dating, a dating application in Europe that was acquired in December 2020. Earlier roles include VP of Engineering at Context Labs, Founder and CPO of datemyschool, and software engineering positions at BNP Paribas and AXA Group Solutions. Meyer holds an MBA from Columbia Business School and a Master of Engineering in Computer Science from Université de Technologie.
