Analysis
Natural raised a $30 million Series A led by Kirsten Green's Forerunner Ventures to build payment infrastructure purpose-built for AI agents, positioning the company directly against Stripe, the incumbent that effectively owns developer-facing payments today. CEO Kahlil Lalji previously co-founded YC-backed banking product Ivella, which he sold to Earnin in 2023, giving him direct experience building consumer financial infrastructure before pivoting to the agent-native version of the problem.
The company's core argument is that traditional payment rails -- credit cards, ACH -- were designed around human authorization at every step, a model that breaks down when the entity initiating a transaction is an AI agent acting autonomously on a person's behalf. Natural wants to be the orchestration layer that lets agents move funds, pay humans, and settle transactions with other agents without a person clicking "confirm" each time, while still preserving the trust and fraud-control guarantees that make payments infrastructure viable at all.
“Visa, Mastercard and Stripe have all shipped their own agent-payment protocols this year, a defensive response to exactly the kind of challenger Natural represents.”
Natural has been operating in beta and has specifically hired senior staff away from Stripe, Ramp and Square -- competitive intelligence and execution experience pulled directly from the incumbents it's targeting, a hiring pattern that tends to accelerate credibility with enterprise buyers evaluating a challenger's ability to actually ship production-grade payments infrastructure.
The market opportunity cited in the raise is substantial if directionally accurate: agentic payments are projected to grow from roughly $7 billion today to $93 billion by 2032, as AI agents increasingly execute purchases, invoices and transfers without human sign-off. Visa, Mastercard and Stripe have all shipped their own agent-payment protocols this year, a defensive response to exactly the kind of challenger Natural represents.
What to watch: whether Stripe responds by acquiring an agent-payments-focused challenger rather than building the capability entirely in-house, and whether Natural can convert its Stripe-alumni hires into genuine production volume before a better-capitalized entrant closes the gap.
