Natural Announces $30M Series A to Build a Payments Stack for Autonomous AI Agents

Natural announced a $30 million Series A led by Forerunner’s Kirsten Green, bringing disclosed funding to more than $40 million. The 17-person startup simultaneously put six products into general availability: agent wallets, restricted vaults, payment sending and requesting, transfers, and marketplace infrastructure. Banking services are supplied by Column rather than Natural itself. Additional card acceptance, issuing, credit, billing, and direct payment-rail products are planned, making this a capital-and-product bet that autonomous agents will require a distinct regulated financial stack rather than merely using existing human-oriented checkout tools.
