Basis Theory builds independent payments infrastructure centered on a developer-friendly, cloud-native vault that tokenizes and stores sensitive payment data while remaining processor-agnostic. The platform allows merchants and fintechs such as Pinterest, Melio, and MoneyGram to keep full control of card and account data, simplifying PCI compliance and eliminating vendor lock-in. Its vault underpins the company’s broader vision for “agentic commerce,” where AI agents autonomously authorize and optimize transactions; Basis Theory also leads a 20-plus-member Agentic Commerce Consortium to set standards for this emerging model. Founded in 2020 by fintech veterans Brian Billingsley, Colin Luce, and Ben Milne, the company has grown to more than 40 employees and holds PCI Level 1 and SOC 2 certifications. Revenue figures were not disclosed, but the firm cites strong product-market fit and plans to expand engineering, product, and go-to-market teams with its new capital. Future initiatives include scaling its enterprise-grade vault globally and deepening AI-driven payment and data capabilities for merchant customers.
