As autonomous AI systems increasingly gain the ability to execute financial and operational actions independently, infrastructure providers are beginning to rethink how identity, authorization, and trust frameworks should function in AI-native environments. Foundationโs latest funding reflects growing interest in hardware-based security models designed for autonomous digital systems.
Foundation has raised $6.4 million in new funding as the company expands beyond Bitcoin self-custody into AI authorization, identity protection, and hardware-based trust infrastructure.
The round was led by Fulgur Ventures with participation from Arche Capital, bringing Foundationโs total funding to $16.5 million.
The company is positioning itself around what it describes as โHuman Authority Hardwareโ – dedicated devices designed to ensure that critical digital actions initiated by AI systems still require explicit human approval.
Foundation argues that as autonomous AI agents increasingly gain the ability to move funds, deploy code, access credentials, and execute operational tasks, existing authorization models may become insufficient for high-trust financial and digital environments.
Its approach centers on isolated hardware devices that remain physically separated from potentially compromised software systems, creating an independent approval layer for sensitive actions.
Alongside the funding announcement, Foundation moved its Passport Prime platform into general availability.
Unlike traditional crypto hardware wallets focused primarily on asset custody, Passport Prime is designed as a programmable authorization and identity infrastructure platform supporting multiple authentication and security functions.
The device includes a โTrusted Displayโ that allows users to independently verify actions before approval, alongside support for Bitcoin self-custody, encrypted secrets management, FIDO authentication, and secure file storage.
Foundation also introduced QuantumLink, a post-quantum encrypted communication protocol built for future cryptographic security requirements.
A major part of the companyโs roadmap involves expanding KeyOS – its Rust-based operating system into a broader developer ecosystem supporting AI-native security and authorization applications.
The platform now includes SDK tooling, simulation environments, and Model Context Protocol integrations that allow AI systems to interact directly with Foundationโs hardware infrastructure for development and validation workflows.
The funding highlights growing investor interest in security and authorization infrastructure designed specifically for increasingly autonomous financial and digital systems.
