BaaS wedge strategy for fintechs
Anthony Peculic, Head of Cards at Cross River Bank, on building a fintech one-stop shop
This is the moment when banking infrastructure stops being a greenfield bundle and becomes a share of wallet fight. A mature fintech like Stripe already has ledgers, compliance workflows, and bank partners in production, so a new supplier has to win one lane at a time, cards, lending, payouts, or deposits, then prove it should handle more. That is why Cross River built a broad menu of APIs and why replacement risk matters as much as new product expansion.
-
For early companies, one provider can stand up accounts, payments, cards, and lending quickly. For scaled fintechs, every product is usually wired into an existing stack, so adding a new bank or processor creates integration work, migration risk, and internal coordination across compliance, engineering, and operations.
-
Cross River makes money across several layers at once, loan origination and interest, ACH and payment fees, card interchange splits, and software. That breadth lets it pitch a large fintech on one missing product first, then expand if that product performs well and the economics beat incumbent vendors.
-
The market split is visible in the competitive set. Stripe bundles many financial tools on top of partner banks for developers who want speed and convenience. Column and Lead Bank show the opposite path, where larger fintechs migrate specific banking relationships as they rebalance for better economics, lending capacity, or tighter control.
The next phase of BaaS will be driven less by signing brand new fintechs and more by selective consolidation around the vendors that can replace an incumbent product cleanly. Banks and infrastructure providers that can start with one high value wedge, then layer adjacent services without forcing a full rebuild, will capture the largest enterprise fintech programs.
