Foundation Raises $6.4M to Pivot from Bitcoin Hardware Wallets into AI Agent Authorization!

Foundation, best known for its Passport line of Bitcoin hardware wallets, has closed a $6.4 million funding round to extend its security expertise into a new frontier: authorizing actions taken by AI agents. The raise signals a deliberate strategic expansion beyond cold-storage hardware into the emerging infrastructure layer that governs what autonomous AI systems are permitted to do — and on whose behalf.

The move makes intuitive sense for a team already deep in cryptographic key management and user-controlled security models. AI agent authorization is an unsolved problem at the intersection of identity, signing, and trust — exactly the domain Foundation has been building in for Bitcoin. The $6.4 million gives them runway to translate that hardware-security DNA into software primitives the agentic AI stack will need.
