Problem
B2B payments platforms often lack a built‑in mechanism to provide their users with instant working capital, forcing them to either develop complex credit infrastructure internally or partner with multiple vendors. Building underwriting, KYB, fraud prevention, and loan‑management capabilities requires significant capital, regulatory expertise, and ongoing operational overhead. As a result, cash‑flow‑constrained suppliers and buyers experience delayed payments, limiting the platform’s ability to grow transaction volume.
Solution
OatFi delivers a single, API‑driven credit and capital‑markets stack that enables B2B payments platforms to embed working‑capital products directly into their existing payment flows. The platform connects to a trusted credit network and capital‑markets providers, allowing instant deferral of payables and acceleration of receivables without the platform raising debt or maintaining its own balance sheet. Automated underwriting, KYB verification, and fraud‑prevention tools generate real‑time credit decisions, while a built‑in loan‑management system handles funding, ledgering, and repayment servicing. By abstracting capital‑market responsibilities, OatFi lets platforms monetize total payment volume and scale credit programs with minimal integration effort.
Target Audience
The primary customers are B2B payments platforms and fintech solutions that manage accounts payable, accounts receivable, spend‑management, procurement, marketplace transactions, or contingent‑workforce payouts and need to embed instant working‑capital products for their users.
