Foundation has raised $6.4 million in a funding round led by Fulgur Ventures, with participation from Arche Capital, to accelerate its expansion beyond bitcoin self-custody hardware into AI agent authorization and broader digital identity security systems.
The company, Foundation, said the new capital will support its move from building hardware wallets for bitcoin storage toward developing secure systems that manage permissions and approvals for AI agents operating on behalf of users. The funding brings Foundation’s total raised capital to $16.5 million.
Alongside the announcement, the company launched general availability of its flagship hardware device, Passport Prime, which integrates a bitcoin wallet, security keys, multi-factor authentication tools, encrypted storage, and a developer interface. Foundation describes the device as part of a new “human authority hardware” category designed to ensure sensitive actions require explicit user approval on trusted hardware.
Foundation also expanded access to its KeyOS platform, a developer system that allows applications to build security policies and identity workflows directly on the device. The company said it plans to introduce an app ecosystem for KeyOS, enabling integrations across bitcoin custody, identity management, and AI-driven automation tools.
Investors backing the round said the shift reflects a broader need for secure authorization layers in an era where AI agents increasingly perform actions on users’ behalf, raising demand for hardware-based approval systems that separate decision-making from execution environments.
Foundation said it will use the funding to scale product development, expand its developer ecosystem, and strengthen its position at the intersection of digital asset security and AI infrastructure.
