Best alternatives to Treasury Prime in 2026
Building a product that needs to hold customer money, issue accounts, or move payments usually means either becoming a licensed bank yourself — a years-long, extremely expensive process — or partnering with one. Treasury Prime is the plumbing that makes the second option realistic: a REST API that plugs your app into a real, FDIC-regulated bank's infrastructure, so you can offer banking features without holding a banking charter. Treasury Prime is a "Bank Operating System" that lets fintechs, neobanks and other companies build embedded banking products through a unified REST API connected to a network of 20+ partner sponsor banks. It provides virtual ledger/sub-ledger account management, ACH/wire/real-time payment rails, white-label digital experiences, and compliance program tooling, plus a developer sandbox for testing before going live. The platform has facilitated over $10B in deposits and 2.5M+ new accounts across its bank partners.
