Modern Card Issuers Win New Programs
Founder of startup card issuing platform on the competitive dynamics of card issuing
This is why modern card issuers are mostly winning net new programs, not poaching the biggest existing ones. Once a large fintech is already live on a processor, switching means moving ledgering, authorizations, card controls, dispute flows, and huge transaction volume without breaking anything, so the safer bet for startups like Lithic or Highnote is to sign the next Ramp or the next vertical SaaS platform before it reaches that scale.

Marqeta’s grip on customers like Cash App is partly product strength, but also migration friction. At large volume, even short downtime is costly, and a processor change would absorb top engineers for months, which lowers real churn risk even when a customer has pricing leverage.

The split in the market is enterprise versus long tail. Marqeta, Galileo, and similar first generation processors went deep with a small number of very large accounts. Newer players are building cloud native, self serve infrastructure for startups and embedded finance teams that need faster launch and lighter onboarding.

That makes card issuing look more like a venture portfolio than classic SaaS. Providers aggregate many smaller programs and hope a few become breakout volume engines. The upside comes from capturing customers early, then keeping them as transaction volume compounds and economics improve with scale.
The next phase is a land grab for the companies that are just now adding cards, wallets, and expense flows into software products. As embedded finance spreads beyond pure fintech into vertical SaaS and large brands, the winners in issuing will be the platforms that onboard developers early, survive the compliance work, and become the default processor before customers are too big to move.
