“Can a 25-year-old FCA-regulated FX and travel money business become the embedded payments infrastructure layer for UK and European SaaS platforms?”
Founded in 2001 as CaxtonFX, a consumer-focused foreign exchange and travel money business regulated by the FCA. Over two decades evolved from retail FX/travel cards into a multi-product SMB payments platform offering international transfers, multi-currency accounts, virtual cards, and expense management. The most significant strategic shift came with the launch of the CXTN API platform and 'Plug and Pay' proposition, repositioning Caxton as an embedded finance infrastructure provider — effectively offering its payment rails, FX engine, card issuance, and ledger as a white-label service for SaaS companies and enterprise clients.
Caxton discloses OpenPayd as its banking provider, according to the Embedded Finance Index 2026.
Caxton does not disclose a bank charter of its own; its banking services are provided through OpenPayd.
Caxton processes payments through OpenPayd and RBS.
Caxton uses OpenPayd and ClearBank for FX and cross-border payouts.
Caxton integrates with QuickBooks, Sage, Xero and NetSuite.
The Embedded Finance Index 2026 maps 4 layers in Caxton's stack: Payments / PSP (OpenPayd and RBS); Banking / BaaS (OpenPayd); FX & payouts (OpenPayd and ClearBank); Accounting (QuickBooks, Sage, Xero and NetSuite).
Caxton is founded in 2001 and headquartered in 2 Leman Street, London, E1 8FA, UK.
