Natural bets AI agents need their own payment rails: $30M Series A vs Stripe
Ex-Ivella founders build agent-first payments (wallets, pay, transfer) so software transacts without humans; Forerunner led a $30M Series A.
Natural
What the business is
Agent-orchestration payments layer that lets AI agents move and store funds — wallets, pay, request, transfer and marketplace rails, with FDIC-insured agent wallets and future card and credit products.
Starting capital：$9.8M seed announced September 2025, then a $30M Series A led by Forerunner's Kirsten Green announced 2026-07-20, bringing total funding to $40M.
How it started
Kahlil Lalji, co-founder of YC-backed couples banking app Ivella (sold to Earnin in 2023), kept returning to agentic payments despite being burned by finance after the zero-interest-rate era; he teamed with Ivella co-founder Eric Wang and ex-Nextdoor engineering manager Walt Leung to found Natural in 2025.
What happened
Natural ran in beta and announced a $9.8M seed in September 2025. On 2026-07-20 it released six products to general availability — FDIC-insured Wallets for agents, Vault, Pay, Request, Transfer and Connect — and announced a $30M Series A led by Forerunner's Kirsten Green, with plans for Voice, Accept and Cards, then Charge, Credit, Direct and Billing in Q4. It positions directly against Stripe, which is racing to build agentic rails, and against stablecoin rivals like Skyfire Systems.
No ending yet — it is still running.
Background
Natural is a San Francisco fintech founded in 2025 by Kahlil Lalji, Eric Wang and Walt Leung. Lalji had built YC-backed banking app Ivella, sold to Earnin in 2023, and kept coming back to the same problem: existing payment rails like cards and ACH were built around human authorization, so AI agents that can find vendors, compare prices and arrange delivery still need a person to actually pay.
The product is an agent-orchestration payments layer: companies integrate Natural so their agents can move and store funds, collect money and transact with humans and other agents. On 2026-07-20 Natural released six products to general availability — FDIC-insured Wallets for agents, Vault, Pay, Request, Transfer and Connect — and outlined a roadmap of Voice, Accept, Cards and, in Q4, Charge, Credit, Direct and Billing.
The same day it announced a $30M Series A led by Forerunner's Kirsten Green, bringing total funding to $40M after a $9.8M seed in September 2025. CEO Lalji said the bet was made a year before the category was widely discussed, and Forerunner's Green framed it as new rails for a new platform shift. Natural is racing Stripe, which is also building agentic payment infrastructure, and stablecoin-focused rivals like Skyfire Systems.
Lalji's core assumption is that machine-speed commerce will multiply the number of payments by two to four orders of magnitude versus human-initiated transactions today. If agents transact autonomously at scale, whoever owns the rails agents spend on could become a foundational layer of the economy; if agent commerce stays niche, the $40M war chest buys a small share of a small market.
What has to be true
- The wedge is architectural: Natural rebuilt authorization for software actors instead of bolting agent features onto human rails — the one gap Stripe's products cannot close by extension.
- Founder credibility compressed the round: Lalji had already built and sold a YC-backed fintech, and the team attracted ex-Stripe, Ramp and Square operators before the category was proven.
- The six-products-at-once GA move front-runs the platform race: owning wallets, pay, request and transfer together makes Natural the default stack rather than one API among many.
- Forerunner's Kirsten Green bought the platform thesis, not a feature — she invests in the future of commerce, and agentic payments is her bet that software becomes the next consumer.
- The stablecoin-plus-bank dual path hedges the biggest uncertainty: if agent commerce needs crypto rails, Natural already plans them; if regulators force traditional rails, those are built too.
What can be applied
When a platform shift changes who authorizes a purchase, rebuilding the rail beats extending the old one — Natural sold the agentic stack before the category existed.
Aftermath
As of 2026-07-20 Natural is live with six products in general availability and a further seven planned through Q4, backed by $40M. The bet is unresolved: Stripe and stablecoin startups are racing for the same rails, and the actual volume of agent-initiated payments is still small. The company's next tests are whether enterprises give agents real money authority, whether FDIC-insured agent wallets earn regulatory comfort, and whether the 'orders of magnitude more payments' thesis materializes before capital runs out.
