Wise
Wise is the fintech that killed the bank's hidden FX markup, but it's not a bank, it's not flawless, and the questions people are really asking reveal exactly what the company's own marketing glosses over.
Wise (formerly TransferWise) is a London-based financial technology company founded in 2011 by two Estonian entrepreneurs, Kristo Käärmann and Taavet Hinrikus. Its core pitch is brutally simple: move money across borders at the real mid-market exchange rate, with a transparent, low fee, no hidden markup buried in the exchange rate, which is exactly how traditional banks have quietly bled customers for decades.
The company went public on the London Stock Exchange in July 2021 via a direct listing, making it one of the UK’s largest-ever tech IPOs at the time. It is not a bank in the traditional sense, it holds various e-money and payment licences across different jurisdictions rather than a full banking licence everywhere it operates. That distinction matters enormously for how customer money is protected.
Wise has grown into a genuine global player, serving over 12 million customers and moving billions of pounds worth of transactions every month. Its multi-currency account and debit card (the Wise card) have made it a favourite among frequent travellers, expats, freelancers, and small businesses who are tired of being gouged on foreign exchange.
Despite the hype, Wise is not without controversy or limitation. Account closures, card declines, compliance friction, and a falling share price have all fuelled user frustration, and a flood of very pointed searches that the brand’s own FAQ page conveniently sidesteps.
