Basis Theory

Basis Theory is a payments infrastructure company that gives merchants a cloud-native, PCI Level 1-compliant vault to tokenize, route, and control sensitive payment data across any payment service provider - without vendor lock-in. Founded in 2020 by fintech veterans from Dwolla, Yodlee, and Klarna, the company has raised roughly $50 million and now positions its vault as the foundation for AI-driven, agentic commerce.
