Revolut
Revolut is a British fintech company offering a “super-app” for digital banking and financial services. Launched in 2015 by founders Nik Storonsky (a former Credit Suisse trader from Russia) and Vlad Yatsenko (Ukrainian developer), Revolut began as a multicurrency travel card allowing users to spend and transfer money globally with minimal fees. It quickly evolved into a full-featured neobank. As of 2025, Revolut operates in 48+ countries and has 65 million customers worldwide, making it one of the fastest-growing fintechs ever. The app provides a suite of services: GBP and EUR bank accounts, debit cards, currency exchange for 30+ currencies at interbank rates, stock and crypto trading, person-to-person payments, bill splitting, and more. Revolut’s growth has been astonishing – it surpassed £3.1 billion in annual revenue in 2024 with £1.1 billion operating profit. The company has raised over $1.7 billion from investors like SoftBank, Tiger Global, and TCV, reaching a private valuation of $33 billion in 2021. In late 2025, a secondary share sale reportedly valued Revolut at $75 billion, vaulting it among the world’s most valuable fintechs. Revolut’s journey has not been without challenges: it faced regulatory hurdles (e.g. its UK banking license was long-delayed), compliance scrutiny, and had to strengthen its governance as it scaled. Nonetheless, the company achieved profitability in 2021 and has continued to grow its user base across Europe, North America, and Asia. Revolut’s mission is to become a “global financial super-app”, consolidating banking, investing, insurance, and payments in one place. It has introduced products like “Revolut Junior” accounts for kids, pay-later services, and expanded into credit in select markets. With over 10,000 employees worldwide, Revolut is now a regulated bank in the EU and other jurisdictions. Its story from scrappy travel card startup to a $75B-valued fintech giant with 65 million users epitomizes Europe’s fintech rise and the potential of challenger banks to rewrite banking norms.
