Metonymous /məˈtänəməs/ — a substitute identity

    Agents need identity.

    Metonymous builds autonomous agents with their own identity, and the infrastructure that powers them. Real accounts, real communication channels, real financial rails.

    METONYMOUS.AI

    AI research and agentic systems that operate natively across established digital infrastructure.

    Our mission is to build functional AI systems that master the decades of existing internet infrastructure, and to build the rails for the next thousand years.

    First-Party Identity

    Distinct digital identities holding real accounts and isolated credentials, not shared or borrowed access.

    Complete Oversight

    Verifiable audit logs and clear boundaries ensure your agent only takes actions you have explicitly approved.

    Native Rails

    Normal SMS, normal bank accounts, normal email. Agents use the same channels you already do.

    Persistent Operation

    Agents run continuously in the background, managing complex, long-term tasks without requiring your constant attention.
