Joe Heneghan, head of Revolut Europe, discusses the challenges fintechs face in the eurozone due to regulatory fragmentation, which hinders cross-border operations. Despite reaching 50 million customers, Revolut encounters issues like IBAN discrimination. Heneghan emphasizes the need for a unified European market, echoing Mario Draghi's recommendations. Revolut views the digital euro as an opportunity rather than competition and plans to expand its product offerings, including mortgages and business lending, while seeking banking licenses in various regions.
