Foundation raised $6.4M led by Fulgur Ventures, bringing total funding to about $16.5M since a 2021 launch. Passport Prime launched with general availability at $349, targeting more than 1M Cake Wallet users through KeyOS cold storage integration. The device combines functions including a bitcoin hardware wallet, FIDO security key, two-factor authentication storage, secrets vault, and 50GB encrypted file storage. Passport Prime runs KeyOS, a Rust-based microkernel operating system developed over three years, and uses QuantumLink for post-quantum encrypted Bluetooth communication. The company plans a KeyOS app store by end of Q2 2026 and expansion into AI agent and identity security, while opening the KeyOS developer platform to outside builders.
"Foundation raised $6.4M led by Fulgur Ventures, bringing total funding to $16.5M since its 2021 launch.

Arche Capital also participated in the round, which brings Foundation's total funding to approximately $16.5 million, according to the firm's release on Thursday."
"Passport Prime functions as a bitcoin hardware wallet, FIDO security key, two-factor authentication storage device, secrets vault, and 50GB encrypted file storage unit in a single handheld device. It runs KeyOS, a Rust-based microkernel operating system Foundation developed over three years, and communicates via QuantumLink, a post-quantum encrypted Bluetooth protocol using ML-KEM and ChaCha20-Poly1305 over an isolated chip. The device is manufactured in the United States at an ITAR-compliant facility."
"Foundation CEO Zach Herbert said the company built Passport Prime to address a security gap that hardware wallets and FIDO keys were never designed to fill. Every era has its key management problem. For bitcoin it was self-custody. For the agentic era it is who actually authorizes the decisions an AI agent takes on someone's behalf, Herbert said. It has to be answered on dedicated hardware, with a display you can trust and an operating system you can inspect."
"The company calls this category Human Authority Hardware, dedicated devices that sit outside the software environment where an AI"
