Payments infrastructure that lets AI agents hold, send and collect money
Natural is payments infrastructure built for AI agents rather than people. It gives autonomous agents their own FDIC-swept wallets, verified identities and a unified API for sending, requesting and transferring funds, so engineering teams can let agents transact at machine speed instead of wiring them into a human-authorized checkout flow.
Natural is a San Francisco financial-infrastructure company building payment rails designed for autonomous AI agents instead of human cardholders. Founded in 2025 by Kahlil Lalji (CEO), Eric Wang (CTO) and Walt Leung (CPO) — a team drawn from Stripe, Ramp, Square and Nextdoor, with Lalji and Wang having previously co-founded and sold the YC-backed fintech Ivella — the company left stealth in early 2026 and raised a $30 million Series A led by Kirsten Green at Forerunner Ventures in July 2026, bringing total funding to roughly $40 million against a 17-person team. The platform is organized as thirteen products, six of which reached general availability by the Series A: Wallets (agent-held accounts whose balances sweep into FDIC-insured deposits through Column N.A.), Vaults (one-way accounts), Pay, Request, Transfer, and Connect for platform and marketplace flows; Voice, Accept and Cards follow, with Charge, Credit, Direct and Billing slated for Q4 2026. Developers integrate through a REST API at api.natural.com, Python (naturalpay) and TypeScript (@naturalpay/sdk) SDKs, a CLI, or a hosted MCP server at mcp.natural.com that plugs directly into Claude, Claude Code, ChatGPT, Codex and Cursor; agents authenticate either through browser OAuth or per-agent API keys held in a secret manager, which is what gives each transaction an attributable actor. Natural publishes list rates — 10 basis points on Pay and Request, 1.5% on instant Transfer, 2.9% plus 30 cents on Accept — and sits directly against Stripe's Agentic Commerce Protocol, Google's AP2, Coinbase's x402 and stablecoin-first rivals such as Skyfire in the contest to become the settlement layer of the agentic economy.
The platform or fintech engineering lead shipping agents that must move real money — they get bank-backed rails, per-agent identity and server-side limits without applying for money-transmitter licences or handing an agent a human's card.
Every agent gets its own funded, attributable wallet with bounded spend, so agent-initiated payments are reconcilable and disputable instead of appearing as anonymous charges on a shared corporate card.

Key Features
- ✓Agent Wallets
Each agent gets its own account whose balance sweeps into FDIC-insured deposits at Column N.A. partner banks, segregating funds per agent rather than pooling them on a shared card.
- ✓Unified money-movement API
One REST API at api.natural.com covers Pay, Request, Transfer, Vaults and Connect, so a single integration handles sending, collecting and moving funds.
- ✓Hosted MCP server
mcp.natural.com exposes payment tools straight into Claude, ChatGPT, Claude Code, Codex and Cursor, so teams do not have to write a custom tool layer.
- ✓Per-agent identity and keys
Agents authenticate with dedicated API keys or browser OAuth, giving every transaction an attributable actor for audit, spending limits and dispute handling.
- ✓Vaults for one-way accounts
Vaults accept funds but do not permit withdrawal, structurally bounding what a compromised or prompt-injected agent can move out.
- ✓Connect for platforms
Marketplace primitives onboard sub-accounts and route funds between agents, businesses and consumers under one integration.
- ✓Published list pricing
Rates are posted publicly at 10 bps on Pay and Request, 1.5% instant Transfer and 2.9% plus 30 cents on Accept, which is unusual in agent-payments infrastructure.
Capabilities
Use Cases
- •Autonomous procurement
A research agent buys API credits, datasets or compute at machine speed from a capped wallet, and finance reconciles the spend per agent afterwards.
- •Agent-run marketplaces
A platform uses Connect to onboard third-party agents as sub-accounts and settle funds automatically between agents, businesses and consumers.
- •Usage-based agent billing
A software vendor charges customers for work its agents perform via Billing and Charge, rather than bolting metering onto a human seat subscription.
- •In-chat commerce
An MCP-connected assistant inside ChatGPT or Claude completes a purchase or collects a payment without the user leaving the conversation.
- •Treasury guardrails for agent fleets
Vaults hold funds one-way so an operations agent can receive but never withdraw, bounding blast radius if that agent is compromised.
Ideal For
Best For
- ✓Giving each autonomous agent its own funded wallet with server-side spending limits instead of sharing one corporate card across a fleet
- ✓Agent-to-agent and agent-to-business settlement inside marketplaces and platforms built on Connect
- ✓Paying for API credits, compute or data an agent purchases at machine speed, then reconciling that spend per agent
- ✓Adding checkout and money collection to an MCP-based agent running inside Claude, ChatGPT, Codex or Cursor
- ✓Usage-based billing for agent work, where metering has to follow the agent rather than a human subscription
Not Ideal For
- ✗Teams that only need human-in-the-loop checkout — Stripe's Agentic Commerce Protocol and existing card rails cover that with far broader merchant acceptance and a decade of production history
- ✗Enterprises that require a long compliance track record: this is a 2025-founded, 17-person company, and its FDIC coverage is pass-through via Column N.A.'s sweep programme rather than a bank charter Natural holds itself
- ✗Regulated institutions needing on-premise or in-VPC deployment, since Natural is an API-only hosted service with no self-hosted option
- ✗Buyers who need the full product line today — seven of thirteen products are unreleased, with Charge, Credit, Direct and Billing only slated for Q4 2026
- ✗Non-USD or cross-border-first operations, as the shipped products and FDIC sweep coverage are US-dollar and US-bank centric
Integrations
Deployment
Market Analysis
Pros
- ✓Published list pricing on most rails is rare in agent-payments and makes cost modelling possible before a sales call
- ✓Per-agent wallets and identities give finance and audit teams attribution that a shared corporate card structurally cannot
- ✓Six products already generally available with a documented REST API, Python and TypeScript SDKs and a hosted MCP server
- ✓Strong operator pedigree — founders and staff from Stripe, Ramp, Square and a prior YC fintech exit — plus $40M from tier-one fintech backers
Cons
- ✗Very early: founded 2025, 17 employees, and the Series A landed 193 days after leaving stealth, so there is no production track record at enterprise scale
- ✗Seven of thirteen products are still unreleased, with Charge, Credit, Direct and Billing only slated for Q4 2026 — integrating today means buying a roadmap
- ✗Practitioner signal is essentially absent: the Series A coverage drew 2-3 points and zero comments on Hacker News, and there is no G2, Capterra or TrustRadius listing, so no independent user reviews exist
- ✗FDIC protection is pass-through via Column N.A.'s sweep programme rather than a charter Natural holds, a distinction treasury teams will question
- ✗The agentic-payments standards contest is unsettled, so committing to these rails is a bet against Stripe's ACP, Google's AP2 and Coinbase's x402, while most large players are hedging across several
- ✗No security or compliance page was reachable, so SOC 2, PCI and similar attestations could not be confirmed

Card issuing & Direct
Contact for pricing
- ✓Custom card-issuance pricing
- ✓Direct payment rails
- ✓Volume rates
Natural publishes unusually specific list rates: 10 bps on Pay and Request, 1.5% on instant Transfer, 2.9% plus 30 cents on card Accept, 3% on Credit, 50 bps on Billing and $1,000/month for Voice. Consumer-tier features are largely free; every business rail still routes through a sales conversation for a contract, and card issuing and Direct are custom-priced. There are no seat fees — cost scales with money moved, so a fleet making many small payments is metered on transaction volume rather than headcount.
