Natural Secures $100M Credit Line for AI Agent Payments

On August 19, 2026, financial technology startup Natural announced it secured a credit facility of up to $100 million from Upper90 Capital Management. This debt financing arrives just one month after the San Francisco-based company closed a $30 million Series A round on July 20, 2026, when the startup was only 193 days old. Led by Kirsten Green at Forerunner, the round brought Natural's total equity base to over $40 million. Founded by Kahlil Lalji, Eric Wang, and Walt Leung, the 17-person team is backed by Human Capital, Abstract, Bridge, Brex, Mercury, Privy, Vercel, Notion, Increase, Unit, and Figure.

The $100 million facility is designed to fund the balance sheet requirements of Natural's upcoming credit products. While equity capital funds software development, debt is required to back the actual transactions and credit lines extended to autonomous systems. Natural is currently building 13 products for the agentic payments stack. Six are already generally available, including Wallets, Pay, Request, Transfer, Vaults, and Connect. The company plans to roll out Voice, Accept, and Cards soon, followed by Charge, Credit, Direct, and Billing in the fourth quarter of 2026. Banking services are provided by Column N.A.

For developers and enterprises deploying AI agents, this infrastructure solves a critical bottleneck in autonomous commerce. Instead of relying on human-managed credit cards or pre-funded accounts, practitioners can now issue dedicated lines of credit directly to their AI agents through Natural's upcoming Credit and Charge products. This allows agents to execute transactions independently, manage API-call billing, and settle payments across multi-bank and multi-currency networks. According to Lalji, the infrastructure must scale because agents will eventually become "the primary financial actors of the global economy."

This financing model mirrors a broader trend where AI infrastructure companies pair equity with massive debt facilities to support capital-intensive operations. For instance, Global AI recently secured a $441 million credit facility for sovereign data centers, and Valar Atomics paired a $1 billion Series B with a $200 million credit facility. By securing $100 million from Upper90, Natural ensures it can scale its payment volume from its first million to its first billion of deployed credit without diluting its equity base.
