Agentrail Raises $28M Series A for Autonomous Agent Payments Across Fiat and Stablecoin Rails

  • Agent Payments
  • Fintech Infra
  • Agentic Economy

Payment infrastructure so production agents can discover, authorize, and settle spend with budgets, counterparties, and reverse paths—without a human on every checkout.

“Agents do not need another wallet UI. They need rails that treat non-human spenders like employees with better audit logs.”

— Founder

“Agent commerce dies when authorization still requires a thumb—Agentrail is building the settlement layer at computer speed.”
