Resource-Intensive BaaS Favored Enterprises
Banking-as-a-Service: The $1T Market to Build the Twilio of Embedded Finance
Early BaaS winners sold to enterprises because embedded finance was still a custom build, not a plug in. Launching a card or lending program meant negotiating with sponsor banks and networks, wiring compliance into onboarding, and staffing operations for disputes, fraud, statements, and support. Large fintechs and big brands were the only buyers with enough engineers, legal help, and patience to survive a three to four month launch and then run the program day to day.

The product itself pushed vendors upmarket. Marqeta handled the processor layer for cards, while Synapse tried to bundle cards, accounts, payments, and lending into one stack. Both models still required customers to make consequential design choices about bank partners, compliance flows, and revenue sharing, which fit enterprise buyers better than startups.

Enterprise customers were worth the effort because each one could become enormous. Marqeta built a business around roughly 160 customers and about $488M in annual revenue, or roughly $3M per customer, with a handful of breakout fintechs like Square driving outsized volume. That made deep, high touch servicing economically rational.

This also explains why early BaaS looked more like professional services than self serve software. Experts describe banks as the pacing factor in launch timelines, with manual compliance review stretching programs from a few weeks for processor setup to several months once the bank is involved. The customer needed budget and internal staff just to get through implementation.
The market has since moved toward more developer friendly and packaged offerings, but the direction is clear. As compliance, bank connectivity, and card controls become more standardized, BaaS shifts from an enterprise only sale into a broader distribution model. The companies that win next are the ones that keep enterprise grade reliability while making launch feel lightweight enough for the long tail of software platforms and vertical SaaS companies.
