Finsei

“Can an FCA-regulated, API-first multi-currency banking platform become the white-label financial infrastructure of choice for European SMBs and fintechs?”

The story

Finsei (originally Altpay Ltd.) began as a digital money-transfer and multi-currency wallet platform for SMEs and individuals. The company has evolved into a broader embedded-finance infrastructure provider, offering multi-currency business accounts, Visa card issuing, and direct card acquiring — all regulated under the UK FCA. Its partner program now enables third parties to white-label the full Finsei stack, positioning it as a B2B2C financial platform rather than just an end-user neobank.
