GrailPay (see Pulse 2.0 profile here) announced it has raised $10.5 million in Series A funding to expand its risk decisioning infrastructure for instant payments and agentic commerce. The round was led by MissionOG, with participation from EJF Ventures, Counterpart Ventures, Construct Capital, Commerce Ventures, and SSC Venture Partners. The new funding brings GrailPay’s total funding raised to $17.2 million.
GrailPay is building a risk and data network for B2B payments. The company said the funding will accelerate expansion of its Payments Identity Network, which serves as a trust layer for bank account risk as business payments become faster, more automated, and increasingly agent-driven.
The company said traditional payments infrastructure has historically relied on time delays and reversibility as buffers against risk. But as instant payments, digital assets, and agentic commerce grow, those buffers are being reduced, creating a need for better identity, authentication, and risk decisioning infrastructure.
GrailPay’s Payments Identity Network covers more than 99% of U.S. bank accounts. The platform provides auditable identity profiles designed to support trust and authentication for agentic payments, instant settlement, guaranteed bank payments, and stablecoin cross-border remittances.
GrailPay’s risk decisioning models combine proprietary first-party processing data from its payments platform with third-party data sources. This gives customers tailored insights into the risk profile of a bank account and the identities associated with it.
Originally launched as a modern bank payments API platform, GrailPay has grown to billions in annualized ACH origination volume while doubling growth quarter over quarter. The company said this processing activity has created a foundation of first-party data that now supports commercial risk decisioning partnerships with major financial institutions and fast-growing fintech companies.
GrailPay said it has had zero churn to date, with customers increasing their spend by more than 200% on average during the first year of partnership.
The company’s platform includes a composable suite of risk products, including Account Intelligence, Transaction Intelligence, and Guaranteed ACH. These products are paired with GrailPay’s API payment processing platform, which supports multiple payment speeds and funds flows.
The Series A funding will support data analytics, modeling research, and go-to-market expansion into agentic and instant payments use cases. GrailPay also plans to expand its Payments Identity Network to deepen coverage for banking and banktech infrastructure, payment processors, embedded fintech platforms, accounts receivable and accounts payable systems, and risk platforms.
KEY QUOTES:
“$80T. That’s the size of the B2B payments economy that will go unaddressed by the flurry of innovation we’re seeing in agentic protocols. We’ve been building foundational infrastructure for the coming wave of B2B payments innovation. Our Payments Identity Network covers over 99% of US bank accounts, providing auditable identity profiles for trust and authentication to usher in the future of agentic payments and instant settlement.”
Will Messina, Co-Founder and CEO of GrailPay
“ACH is the backbone of B2B commerce but has never had the risk and authorization infrastructure that card networks have had for decades, a gap that only grows as payments become instant and autonomous. GrailPay built this trust layer the hard way, combining money movement with risk intelligence to create a data flywheel that gets smarter with every transaction. Will and the GrailPay team have the domain expertise and product vision to make the future of payments faster and safer, and we’re thrilled to partner with them.”
