Processors and BaaS Platforms Provide Functionality

The real product in BaaS lives in the software layer, not the sponsor bank. The processor and BaaS platform are the systems that actually open accounts, issue cards, route authorizations, keep ledgers, run KYC flows, and expose APIs, while the bank mainly decides which programs it will sponsor and how strict the compliance process will be. That is why two fintechs can use different banks and still get nearly the same customer experience if the same processor sits underneath.

• In practice, the processor is the engine between bank and network. It handles card issuance, authorizations, clearing, and settlement. Many all in one BaaS companies still rely on processors like i2c, Galileo, Marqeta, Visa DPS, or Lithic underneath, which shows where the functional heavy lifting actually sits.

• What the bank contributes is approval, oversight, and compliance posture. Banks choose whether they will support prepaid, debit, or credit programs, and they often become the pacing item on launch because documentation review and compliance sign off can stretch a launch from weeks to months.

• This split explains the main trade off in the market. Going direct to a processor gives a fintech more control, more flexibility, and usually a larger share of revenue. Using an all in one BaaS platform adds program management, bank matchmaking, and compliance support, but takes a larger cut and can reduce direct control over the bank relationship.

Over time, more of the value pool should keep shifting toward the platforms that own the software primitives, data model, and multi product orchestration layer. Banks will remain essential because they hold the charter and face the regulator, but the winners in embedded finance are likely to be the companies that make those bank relationships feel interchangeable to the fintech building on top.
