GrailPay, the FRAUD and data network for B2B payments, has raised $10.5 million in a Series A led by MissionOG, with participation from EJF Ventures, Counterpart Ventures, Construct Capital, Commerce Ventures, and SSC Venture Partners, bringing total funding to $17.2 million. The company’s Payments Identity Network covers over 99% of U.S. bank accounts and provides auditable identity profiles for trust and authentication across ACH, instant payment, and agentic payment rails, addressing the same structural gap that has made card networks so resilient for decades while the $86 trillion ACH system has lacked equivalent risk infrastructure. With zero churn to date and customers growing spend over 200% in their first year, GrailPay is positioning itself as the trust layer the B2B payments economy will require as agentic payments, stablecoin remittances, and instant settlement become mainstream.
