Revolut

Nikolay Storonsky founded Revolut in July 2015 after becoming frustrated with the foreign exchange fees charged by traditional banks. Storonsky, a former derivatives trader at Credit Suisse and Lehman Brothers, launched Revolut with a prepaid card that offered interbank exchange rates with no markup. The product launched at a London fintech event. Three thousand people signed up in the first day. Within a decade, Revolut would become the most valuable fintech startup in European history.

A 2018 Wired investigation described Revolut's internal culture as one of the most intense in British tech — with employees expected to work unpaid trial periods, leadership described as confrontational, and an obsession with metrics over wellbeing. Storonsky disputed many of the claims but acknowledged that Revolut's early culture had been built for speed over sustainability. The controversy prompted changes to HR practices but did not slow growth. Revolut reached 2 million users that year without a significant marketing budget.

Revolut raised funding at a $33 billion valuation in July 2021 — making it the most valuable private technology company in the United Kingdom. Simultaneously, its UK banking licence application stalled at the Financial Conduct Authority for over three years, with regulators reportedly concerned about corporate governance and financial controls. The wait became a symbol of European regulators' difficulty keeping pace with fast-growing fintech companies.

Revolut received its UK banking licence in July 2024 after a three-year wait. In November 2025, a secondary share sale valued the company at $75 billion — with Nvidia's venture arm among the new investors. Full-year 2025 revenue hit $6 billion, up 50% from 2024, with pre-tax profit of $2.3 billion. Revolut processed $1.7 trillion in transaction volume. The company had reached 70 million users globally — more than HSBC and Barclays.

In March 2026, Revolut filed for a U.S. national bank charter — a move that would allow it to offer insured deposits and lending to American customers directly. CEO Nikolay Storonsky told investors an IPO was "approximately two years away," with the company targeting a valuation of up to $200 billion when it eventually lists. The prepaid card that had launched to three thousand people in 2015 had become the foundation of one of the most ambitious financial services companies in the world.
