NEW YORK--(BUSINESS WIRE)--OatFi, the API-first fintech infrastructure company modernizing how B2B payments are financed, today announced it has raised a $24 million Series A led by White Star Capital, with continued participation from existing investors Portage and QED.

OatFi solves one of the most fundamental pain points in B2B commerce: payment terms. By embedding its underwriting, origination, and funding capabilities directly into B2B payment platforms within their Accounts Payable (AP), Accounts Receivable (AR), and commercial charge card workflows, OatFi enables platforms to facilitate B2B transactions with built-in financing at the point where it's needed most.

“B2B payments are not just a money movement challenge—they’re a data and workflow challenge,” comments Michael Barbosa, Co-founder & CEO of OatFi. “That’s why we’ve focused on deep API integrations that offer working capital solutions within the platforms that businesses already rely on to pay and get paid.”

The company’s API-first approach is purpose-built for integration into the existing workflows of AP/AR systems, issuer processors, and payment platforms. OatFi already counts leading infrastructure players like Unit, Transcard, and Galileo as partners, and has integrated with over 25 platforms over the past three years.

In traditional B2B transactions, buyers and suppliers often operate on opposing cash flow incentives. Suppliers seek fast post-delivery payments to recover working capital, while buyers look to delay payments to preserve operating cash and liquidity. This fundamental misalignment has historically relied on outdated solutions like checks, or required suppliers to act as de facto lenders to their customers.

OatFi solves this problem with a modern set of APIs that provides a seamless, behind-the-scenes credit layer that delivers the real-time underwriting, ledger and capital to facilitate these transactions. Through OatFi's APIs, parties on both sides of the transaction can operate on their terms without compromising working capital.

“Payment terms determine a business’s cash flow conversion cycle—regardless of size,” Barbosa added. “We’re solving this problem where it matters most: at the point of invoicing and payment.”

“OatFi isn’t a ‘cherry on top’ for B2B payment companies looking to unlock a new revenue stream,” said Eddie Lee, General Partner at White Star Capital. “It delivers a table-stakes product that enables trusted B2B transactions in a world moving rapidly online. First-generation fintech lenders offering MCA products helped support merchants serving consumers. OatFi is helping platforms facilitate commerce between businesses, where the stakes—and the volumes—are even higher.”

With this funding, OatFi will accelerate product development and integrations across AP, AR, and payments infrastructure providers – advancing its mission to build the modern credit network powering the $35 trillion in annual US B2B payments.
