OatFii, the API-first fintech infrastructure company modernizing how B2B payments are financed, has raised $24 million in Series A funding led by White Star Capital to expand its API-first fintech infrastructure that brings embedded credit capabilities to B2B payments platforms. By integrating underwriting, origination, and funding directly into AP, AR, and commercial card workflows, OatFi addresses the longstanding cash flow misalignment between buyers and suppliers at the point of invoicing. With over 25 platform integrations and partners like Unit, Galileo, and Transcend, the company aims to build a modern credit network to support the $35 trillion U.S. B2B payments market.
