Tesouro

Tesouro offers a modular financial software suite that banks deploy to small and medium-sized business customers through their existing bank infrastructure. The product set spans embedded banking, money movement, bill pay, invoicing, expense management and underwriting. The company positions its platform as sitting between a bank partner, which supplies demand deposit accounts, cards and money movement, and software platforms such as vertical SaaS providers, which supply the brand and user experience, with Tesouro providing the embedded finance layer along with compliance, audit and risk functions.

The platform is presented as three offerings. Embedded Banking lets a bank sponsor a vertical SaaS or fintech program without building the underlying infrastructure itself, aimed at banks whose partners are asking for banking inside their own products. The FinOps Hub bundles accounts payable, accounts receivable, expense management and Tap-to-Pay so that a bank's SMB customers can access these functions without leaving the bank. The Underwriting Platform consolidates decisions into a single queue governed by the bank's own risk rules, returning decisions in minutes with what the company describes as examiner-grade audit trails, and references integrations or connections with providers including Fiserv and Worldpay.

Tesouro frames its market thesis around banks having lost SMB relationships to fintechs on speed of shipping rather than trust, citing Capital One's reported acquisition of Brex, Mercury's SMB customer base and pending bank charter, and Ramp's revenue scale as evidence that embedded financial tooling has become a strategic category.

Business model

Tesouro sells its software to banks, which in turn deploy the tools to their SMB customers and to partner software platforms; the offering is described as modular and designed to run on a bank's existing core infrastructure rather than requiring the bank to build its own embedded finance stack.
