“Can a bank-direct BaaS platform survive — and become the operating system for fintech-bank partnerships — by aligning with banks rather than abstracting them?”
Founded 2017 as a BaaS API platform connecting fintechs to a small set of partner banks. After the post-2023 BaaS market shakeout, Treasury Prime shifted to a 'bank-direct' model — fintechs contract directly with the bank, with Treasury Prime as the software layer — and introduced OneKey for multi-bank deposit programs. Strategy now emphasizes embedded banking for enterprises and a partner marketplace layering KYC, payments, and accounting on top of the core platform.
