GrailPay Secures $10.5M Series A to Revolutionize Risk Infrastructure for Agentic and Instant Payments

Quick Summary

GrailPay has raised $10.5 million in Series A funding to scale its risk decisioning infrastructure for the $80 trillion B2B economy. By providing a trust layer for instant payments and agentic commerce, GrailPay enables secure, zero-fail transactions across 99% of U.S. bank accounts using its proprietary Payments Identity Network.

How Does GrailPay Solve Risk for Instant B2B Payments?

Risk decisioning infrastructure is the critical missing piece for modern B2B commerce, which has historically lacked the robust authorization layers found in consumer card networks. GrailPay addresses this by aggregating proprietary first-party data with third-party sources to create comprehensive risk profiles. This approach moves beyond legacy siloed datasets that offer binary outcomes without context.

• 99% coverage of all U.S. bank accounts within the Payments Identity Network.
• Billions in volume processed through annualized ACH origination.
• Zero customer churn recorded since the company's inception.

By combining money movement with deep risk intelligence, the platform creates a data flywheel that improves with every transaction, ensuring that instant settlement does not come at the cost of security.

What Role Does Agentic Commerce Play in This Expansion?

Agentic payments represent the next frontier where AI agents and autonomous protocols execute transactions without manual intervention. GrailPay is positioning its risk decisioning infrastructure as the foundational trust layer for these high-speed environments. Traditional buffers like time and reversibility disappear in instant payment rails, making real-time authentication essential.

• 200% average growth in customer spend during the first year of partnership.
• Quarter-over-quarter doubling of growth metrics for the core platform.
• Composable risk products including Account Intelligence and Transaction Intelligence.

This infrastructure supports diverse use cases ranging from stablecoin cross-border remittances to guaranteed ACH, providing the necessary underwriting for autonomous commerce to scale globally.

"$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." said Will Messina, Co-founder & CEO, GrailPay

FF NEWS TAKE:

GrailPay is tackling the "final boss" of B2B finance: the lack of real-time trust on ACH rails. By building a risk decisioning infrastructure that mirrors the sophistication of Visa or Mastercard for the bank-to-bank world, they are effectively de-risking the future of autonomous finance. This $10.5M injection isn't just a capital boost; it's a signal that the industry is ready to move past slow, batch-based legacy systems toward a truly instant, agentic future.
