OatFi Raises $24M: Modernizing B2B Payment Financing

OatFi, an infrastructure company specializing in fintech APIs for B2B payments, has successfully raised $24 million in a Series A funding round led by White Star Capital with significant contributions from ongoing investors Portage and QED. This financial injection is aimed at advancing its innovative approach of embedding underwriting and funding solutions directly into B2B payment platforms within their Accounts Payable (AP) and Accounts Receivable (AR) workflow. Addressing a core inefficiency in B2B commerce—payment terms—OatFi’s API-first infrastructure provides seamless integration with existing AP/AR systems, issuer processors, and payment platforms. It ensures that buyers and suppliers overcome cash flow discrepancies without compromising working capital, thus replacing outdated credit solutions with real-time underwriting, ledger, and capital management capabilities. OatFi’s solutions are seen essential for facilitating transaction platforms to capitalize on the rapid digitalization of B2B commerce, marking its role as both a disruptive and necessary component in modern business transactions. With new funding, OatFi plans to accelerate product development and integration efforts to aid AP, AR, and payment infrastructure providers—fueling its vision to support the extensive $35 trillion in annual B2B payments in the U.S.
