GrailPay raised $10.5 million in a Series A round on Jun 25, 2026, led by MissionOG with participation from EJF Ventures, Counterpart Ventures, Construct Capital, Commerce Ventures, and SSC Venture Partners. The round brings total funding to $17.2 million. GrailPay operates a risk and data network for B2B payments, built on a Payments Identity Network covering over 99% of US bank accounts.

The company aggregates proprietary first-party processing data from its payments platform with third-party sources to assess bank account risk and associated identities. GrailPay has grown to billions in annualized ACH origination volume while doubling growth quarter over quarter, with zero customer churn to date. Funding will go toward data analytics, modeling research, and go-to-market expansion into agentic and instant payments use cases.
