Direct Sponsor Bank Access for Scale
Bo Jiang, co-founder and CEO of Lithic, on the key primitives in card issuing
Wanting a direct line to the sponsor bank is a sign that a card program has outgrown starter infrastructure and is becoming a real financial product business. At small scale, a platform can hide the bank and handle approvals, compliance workflows, and economics. At larger scale, the fintech wants to negotiate interchange, shape KYC and AML rules, launch adjacent credit or debit products, and make sure the bank understands the program well enough to support more bespoke use cases.

The bank is the regulated party behind the card. Sponsor banks increasingly want direct visibility into large programs because they are ultimately responsible for compliance, funds flow, and who is being sponsored. As the program gets bigger, tighter bank fintech process becomes part of the operating model, not just onboarding.

A direct bank relationship also changes the economics. Larger fintechs can push for cleaner passthrough interchange and avoid extra platform take rates, while also gaining more control over card design, policy rules, physical card vendors, and product expansion. That matters when margins are thin and every basis point counts.

This is one reason issuer processors like Lithic fit scaled builders better than all in one BaaS stacks. A company can keep its own ledger, pick its own KYC tools, and bring a credit core or ACH provider, while using the processor for authorization, controls, and network connectivity. The trade off is more integration work up front.
The market is moving toward more formal bank fintech partnerships, with larger programs choosing either direct bank relationships or platforms that can support that level of transparency and control. The winners will be providers that let customers start fast, then unbundle pieces of the stack as scale makes customization, economics, and sponsor bank access more important.
