May 22, 2026 – Bitcoin hardware wallet manufacturer Foundation Devices has secured $6.4 million in new funding led by Fulgur Ventures, with participation from Arche Capital, to accelerate its expansion into identity management, multi-factor authentication, and AI agent authorization.
Fulgur Ventures Partner Oleg Mikhalsky said the investment supports companies solving large-scale problems through secure, open-source technology. “Foundation is extending the discipline of self-custody and explicit user approval beyond Bitcoin into identity and AI authorization,” he noted.
The funding brings Foundation’s total capital raised to $16.5 million, underscoring investor confidence in its vision of secure digital autonomy.
The company also announced the launch of its flagship device, Passport Prime, which integrates a Bitcoin hardware wallet, FIDO security keys, two-factor authentication storage, and 50GB of encrypted memory. The device, part of Foundation’s new “Human Authority Hardware” category, ensures that sensitive actions require explicit human approval.
CEO Zach Herbert emphasized the importance of trusted hardware in the AI era: “For the agentic era, the question is who authorizes the decisions an AI agent takes on someone’s behalf. That answer must come from dedicated hardware you can inspect and trust.”
Foundation further expanded access to its KeyOS developer platform, enabling developers to build secure applications and policies within dedicated hardware. CTO Ken Carpenter described KeyOS as “the trust layer for everything you do online,” with plans for a KeyOS app store launching later this quarter.
With integrations already underway — including Cake Wallet — Foundation is positioning itself at the intersection of crypto security and AI authorization, redefining how users safeguard their digital identities in an increasingly automated world.
