fastest credible path from zero to a launched business-banking product for a vertical SaaS team without banking expertise.","fix":"You inherit the middleware-platform risk profile — a layer between you and the bank, per-account/interchange economics that compress at scale, and exposure to Unit's own bank-partner relationships; sophisticated teams eventually outgrow it."},{"rank":3,"product":"Increase","reason":"Developer-grade API with unusual depth on the actual payment rails (ACH, RTP, wires, checks, lockbox) and direct Fed-adjacent infrastructure rather than reselling a processor; near-tie with Column for engineering quality — ranked below because its bank footing is less self-contained and its product surface for full business-banking programs (cards, lending) is narrower.","fix":"Rails-first and minimalist — you're assembling a banking product from primitives with little program-management or compliance scaffolding; wrong choice if you need a packaged BaaS program."},{"rank":4,"product":"Stripe Treasury","reason":"For platforms already on Stripe Connect, embedding business financial accounts (backed by partners like Fifth Third) plus Issuing cards is nearly frictionless, with Stripe's operational maturity, docs, and money-movement integration into payments/payouts;
