Natural raises $30M Series A to build payment infrastructure for AI agents

Natural, which builds payment infrastructure for AI agents, raised a $30 million Series A led by Kirsten Green at Forerunner Ventures. The company was 193 days old at close.

What Natural does

The product gives AI agents a set of financial primitives: storing balances, paying and requesting other agents, businesses, or consumers, and transferring funds between external and internal accounts. Card collection over the phone and additional payment flows are expected by end of Q3. Lalji describes the stack as purpose-built rather than retrofitted — a unified architecture that lets agents run an unlimited number of financial flows without the constraints of rearchitecting an existing payment system.

“Natural builds payments infrastructure for agents. We're announcing today that we raise a $30,000,000 series a led by Kirsten, the runner... Agents execute a majority of global payment volume over the next decade. That world is monopolistic or duopolistic in nature because payments are a highly network effects driven business, and that world is determined in the next twelve months.”

The competitive frame

Lalji is direct that this isn't a play against Stripe specifically. He frames the total addressable market as JPMorgan plus Stripe plus Visa — a bank, a payment service provider, and a network — rather than a slice of existing processor volume. The logic is that agentic payments will be structurally larger than any current incumbent's footprint, and that payments are network-effects-driven enough to produce a monopolistic or duopolistic outcome.

Why the next 12 months matter

Lalji argues the default developer choice for agentic payments in 2027 will likely hold through 2035. That makes the current period a land grab, even if the category doesn't feel like one yet. The window to become the default is short, and Natural is trying to own it from the ground up rather than compete on features with incumbents who are retrofitting existing rails.

The bet is high-conviction and time-sensitive. If agentic payment volume scales the way Lalji expects over the next decade, whoever owns the developer default owns a very large network.
