Few banks combine charter and APIs
Stripe's stablecoin bank
This points to a winner take most market structure in regulated fintech infrastructure. In practice, very few U.S. banks both hold their own charter and expose modern APIs that let a fintech programmatically open accounts, move money over ACH, RTP, and Fedwire, and issue cards without sitting on top of a separate middleware layer. That makes Lead Bank and Column unusual because they combine the bank, the ledger, the compliance team, and the developer surface in one stack.

Lead Bank was rebuilt from a Kansas City community bank into an API first bank after Jackie Reses and former Square executives acquired it in 2022. Its partners use Lead directly for FDIC insured accounts, lending, payments, and card issuance, with Lead earning transaction fees, interchange share, and interest income.
-
Column is the main comparable. It also owns the charter and exposes its own API, and it has become the home for major neobanks like Brex and Mercury. That is the other clear example of the same vertically integrated model, which is why the field narrows to two rather than dozens of sponsor banks.
-
Most other BaaS players have historically been middleware companies like Unit, Synctera, and Treasury Prime. They connect fintechs to third party banks, but do not themselves control the charter. The strategic difference is concrete, one vendor can ship faster and with fewer handoffs than a fintech, middleware platform, and sponsor bank chain.
Going forward, more fintech volume should consolidate into charter plus API banks because regulators and large customers increasingly prefer fewer dependencies in the money movement stack. That should keep Lead and Column in an advantaged position, with Lead leaning into lending and stablecoin programs, and Column leaning into neobanks and core account infrastructure.
