Basis Theory, a leading payments infrastructure company offering the industry’s first programmable payment vault, is announcing a $33 million Series B round led by Costanoa, with participation from Stage 2 Capital, Moneta VC, and continued support from Bessemer Venture Partners, Kindred Ventures, Box Group, and Offline Ventures.
The new funding will accelerate Basis Theory’s agentic commerce advancements, and expand its enterprise-grade payments solutions for global merchants.
As merchants seek flexible, secure ways to manage payment credentials across providers, payments are becoming a strategic growth lever. Building these capabilities in house requires navigating significant security, compliance, and technical complexities. But with Basis Theory, customers such as Pinterest, MoneyGram, Melio, Engine, and Orum (acquired by Stripe) can tokenize and manage payment data—while maintaining control over how it is accessed and used within their own systems or with external partners.
Basis Theory offers enterprises a cloud-native, PCI-compliant vault that operates independently of any payment processor or orchestration layer. This means enterprises can capture payment data right at the point of sale and use it however they’d like. Today, Basis Theory is the most flexible and scalable payment vault available in the industry—and it serves as a unified platform for agentic commerce.
Basis Theory provides policy controls, compliance support, and programmable integrations to securely store, share, and update sensitive payment data across agentic commerce workflows.
Fueled by partnerships with leading networks, the Basis Theory platform brings the fragmented AI landscape together into an ecosystem.
The company was founded in 2020 by fintech veterans Brian Billingsley, Colin Luce, and Ben Milne, whose experience spans industry leaders like Yodlee, Dwolla, and Klarna. Today, Basis Theory has nearly 40 full-time employees, with plans to expand its engineering, product, and go-to-market teams to meet growing demand and unlock the next era of innovation in AI-driven commerce.
