Foundation raises $6.4M, launches Passport Prime

Foundation said on May 21 it raised $6.4 million in a funding round led by Fulgur Ventures and opened general sales of Passport Prime, a new hardware device that combines a Bitcoin wallet with identity and authentication features. Arche Capital also joined the round, the Boston-based company said, bringing Foundation’s total funding to $16.5 million. The announcement paired the financing with a broader product push: Foundation also said it was expanding outside developer access to KeyOS, the software platform that runs the device. Foundation has described Passport Prime as “Human Authority Hardware,” a category it says is meant to require explicit user approval for sensitive digital actions. ### What exactly did Foundation launch alongside the funding round? Passport Prime is Foundation’s new flagship hardware device, and the company says it is now generally available. Foundation said the product combines a Bitcoin hardware wallet, FIDO security key support, two-factor authentication code storage, a password or secrets vault, and encrypted file storage in one device. The company’s product page says the device is designed to secure Bitcoin, 2FA codes, security keys, important files and additional seeds through a touchscreen interface. (foundation.xyz) Foundation said Passport Prime includes 50 gigabytes of encrypted storage. The company also said the device runs on KeyOS, an open-source operating system written in Rust, and is built to support third-party applications. Foundation’s website says the product includes a security processor with active tamper protection and a dedicated secure element.

Fulgur Ventures led the $6.4 million round, and Arche Capital participated, according to Foundation’s May 21 announcement. Foundation said the new financing brings its cumulative funding to $16.5 million. The company did not disclose the valuation or structure of the round in the announcement surfaced through FinanceWire and republished by Markets Insider. (foundation.xyz) Boston-based Foundation said the capital will support its expansion from Bitcoin self-custody into identity, multi-factor authentication and AI-agent authorization. That framing came from the company’s announcement and was echoed in follow-on coverage from Bitcoin Magazine and other crypto outlets.

The company’s materials describe it as a personal security platform that combines wallet functions with login credentials, authentication keys and encrypted local storage. On its purchase page, Foundation says users can extend the device’s functionality with third-party apps, starting with Cake Wallet. (financewire.com) The company’s “Human Authority Hardware” language ties the device to a broader pitch around trusted approvals. Foundation said KeyOS is designed for applications including AI-agent authorization, identity and programmable security. That description comes from the company’s own launch post rather than an independent technical standard. ### When did Passport Prime become available, and what comes next? (foundation.xyz) Foundation said Passport Prime began shipping to pre-order customers in March and is now available for general sale. Product listings indexed this week showed pricing starting around $349, though Foundation’s main product pages emphasize features and availability rather than a financing narrative. (foundation.xyz) By the end of the second quarter of 2026, Foundation said it plans to launch a KeyOS app store for all users. The company also said outside developers now have expanded access to the KeyOS platform, making that software rollout the next named milestone after the funding and hardware launch. (financewire.com)
