Natural Raises $30M Series A to Build Payment Infrastructure for AI Agents

Summary

Natural, a fintech startup founded just 193 days ago, has closed a $30 million Series A funding round led by Forerunner Ventures' Kirsten Green, bringing total funding to over $40 million. The company is building specialized payment infrastructure designed exclusively for AI agents—a new class of financial actors that will hold wallets, accept payments, settle invoices, and move money autonomously without human authorization.

Natural operates as a full-stack payments company, owning its own ledgering, multi-bank settlement, fraud checks, and compliance layer rather than renting infrastructure from incumbents like Stripe. The company already has six products live, including FDIC-insured agent wallets, transaction "vaults" with embedded guardrails, fund transfer tools, and marketplace infrastructure. It plans to launch 13 products in its first year with a lean team of 17 people, including agent-issued debit cards, voice-based card authentication, per-API-call billing, and credit lines for agents.

The market opportunity is substantial but nascent. Current agentic payment volumes are estimated at just $28,000 per day globally, but forecasts suggest the market could grow from $7 billion today to $93 billion by 2032. Natural faces competition from established players like Stripe—which is adding agentic features to its platform—and earlier-stage startups like Ralio and Paygentic. CEO Kahlil Lalji argues that regardless of market timing, the question is not whether AI agents will handle money, but who builds the infrastructure. Forerunner's bet reflects confidence that Natural has the product instinct and speed to capture share in this emerging payments category before larger incumbents dominate the space.

• Natural competes against Stripe (which is adding agent features) and earlier-stage startups, betting on speed and consumer-DNA infrastructure building to win the emerging category
