British payments platform that rolls acquiring, gateway and processing into a single API — a head-on rival to Adyen and Stripe.
Founded in 2012 by Swiss entrepreneur Guillaume Pousaz, headquartered in London. The pitch is full-stack: instead of chaining together an acquirer, a gateway and a processor from different vendors, the company does all of it in-house and sells it behind one API. Its customers are large merchants rather than one-person shops.
In January 2022 it was valued at $40 billion, making it Europe's most valuable startup. Less than a year later management marked its own internal valuation down to around $11 billion — a sober reminder that the fintech multiples of the pandemic years were, in large part, borrowed.
