About
Basis Theory is a payment vault that routes, tokenizes, and optimizes payments to drive the metrics that matter most to merchants. Customers can tokenize transactions made with a credit card, Apple Pay, or Google Pay while staying compliant with PCI, SOC 2 Type II, ISO 27001, and HIPAA regulations. The platform serves ecommerce, subscription, vertical SaaS, and creator economy businesses, adding redundancy to protect against being shut down by a single PSP.
