Wise

Taavet Hinrikus and Kristo Käärmann founded TransferWise — now Wise — out of personal frustration: both were European workers in the UK who were losing money every month on unnecessary currency exchange fees charged by traditional banks. Rather than accept it, they invented an alternative system built on the real exchange rate — the mid-market rate shown on Reuters or Google, without the hidden margins banks silently add on top. The insight was disruptive because it exposed what banks preferred not to communicate: the true cost of an international transfer is not just the visible fee, but the unfavorable exchange rate applied to the conversion. Wise built its infrastructure on this principle of complete transparency, showing users exactly how much they are paying and why before they even confirm the transaction. Today Wise is far more than a simple transfer service. The platform offers multi-currency accounts, debit cards usable worldwide, international business payments, and a B2B payment infrastructure for companies that need to send or receive money in multiple currencies. In FY2024 the platform processed £118 billion — a number that speaks to the scale reached by something that started as a workaround between friends. In July 2021, Wise listed on the London Stock Exchange through a direct listing, becoming one of the most significant European tech IPOs of the year. The economic model rests on transparent, low fees applied to each transfer, supplemented by revenues from cards, accounts, and interest on deposited balances. The strategy is the classic high-volume, low-margin approach: reduce the cost to the point where the service becomes the obvious choice for anyone moving money across borders. Wise today is a benchmark for anyone building financial products founded on trust: it demonstrates that genuine transparency is not merely an ethical value but a concrete competitive advantage.
