Brex becomes Galileo competitor
Fintech investor on how banking-as-a-service platforms build partnerships
The real shift is that Brex stops being just a fintech customer of infrastructure and starts becoming infrastructure itself. Galileo sits in the layer that handles card authorization logic, transaction processing, fraud controls, and program operations for fintechs. If Brex builds those capabilities for its own card and account stack, then packages them as APIs, it moves into the same job in the value chain, which is the software and operations layer other fintechs pay to use.

Galileo is an API first issuer processor. It helps fintechs launch cards and accounts without building the bank, network, and processor plumbing themselves. Ramp described players like Galileo as abstracting bank and network relationships into robust APIs, plus helping with card manufacturing and operational setup.

The capabilities named here are not cosmetic features. Authorizations decide in milliseconds whether a card swipe is approved. Fraud scoring flags risky transactions. Portfolio reporting turns raw card activity into controls and analytics. Those are core processor functions, so internalizing them cuts vendor spend and creates a sellable product.

This is the common arc in fintech infrastructure. Companies start by buying point solutions, then pull the expensive or strategically important pieces in house as volume grows. The BaaS market has long split between all in one platforms and point solutions, and building inward from a high volume fintech is how a customer can become a competitor.
The next step is more fintechs turning scale into vertical integration, especially around card controls, ledgering, risk, and money movement. As companies like Brex and Ramp grow, the winners will keep more of the stack for themselves, then decide whether to expose that internal machinery as infrastructure and capture revenue from the layer they once bought from vendors.
