Bank Supply Bottleneck in BaaS
Peter Hazlehurst and Kris Hansen, co-founders of Synctera, on BaaS in 2023
The bottleneck in BaaS has usually been bank capacity, not fintech ideas. A fintech can code a card, account, or payout flow in weeks, but each launch still needs a sponsor bank willing to underwrite the risk, review the program, and monitor it after go live. That is why Synctera built a marketplace model, because the scarce asset is not software, it is compliant bank supply that can absorb many different fintech programs at once.

Synctera framed the market this way in both 2022 and 2023. In 2022 it described 10x to 15x more fintechs than bank slots, then in 2023 it said the real constraint was still too few homes for even plain vanilla embedded finance programs, not just edge cases like cannabis or gambling.

This mismatch exists because a sponsor bank is doing more than renting out a charter. In practice the bank has to approve KYC rules, transaction limits, disclosures, ledger visibility, and case handling. One successful fintech can be operationally heavy, which limits how many strong programs a community bank can safely support at once.

The market later split in two directions. Middleware networks like Synctera, Unit, and Treasury Prime tried to increase the number of bank and fintech matches, while vertically integrated banks like Column pulled charter, ledger, payments, and compliance into one stack, then won large programs from Brex and Mercury as regulation tightened around middleware.
The next phase is a race to turn scarce bank supply into scalable infrastructure. Some platforms will do it by helping each sponsor bank handle more programs with better tooling and oversight. Others will do it by becoming software heavy banks themselves. Either way, the winners will be the ones that make a bank comfortable launching more fintechs without losing sight of risk.
