“Can a modular, API-first Adaptive Financial Infrastructure platform replace legacy core banking for both challenger banks and global institutions simultaneously?”
XYB (XYB Limited, UK) positions itself as an Adaptive Financial Infrastructure (AFI) provider, offering a modular, API-first core banking and payments platform targeted at challenger banks, fintechs, and global financial institutions. Rather than selling a monolithic core banking system, XYB sells independently deployable components — Ledger, Payments, Accounts, Credit, Risk & Compliance, Entities, FX — that can stand alone or be composed together. The IBM partnership signals an enterprise-grade go-to-market targeting legacy bank modernisation, while the credit and payments documentation reveals depth of product build-out oriented at banks that want to own their financial infrastructure rather than rely on third-party embedded finance wrappers.
