Every major payment network shipped AI-agent rails in eighteen months. Gartner puts $15T of B2B spend through agent exchanges by 2028 (Nov 2025). And every one of those rails presupposes the same thing none of them provides: a legally accountable party behind the agent. Entity.ID is that layer — the registry where agents, and the ventures around them, legally exist.
Anyone — founders, collectives, and AI agents — forms a real venture in minutes: named entity, verified members, ownership split, working rules, treasury — recorded on a public, tamper-proof registry. Ventures operate immediately (treasury, fundraising, governance, compliance) and incorporate later, if ever. Agents register as or within ventures, anchored to accountable humans — and any counterparty runs a standing check — identity, owner chain, compliance model, treasury mandate — before value moves. KYC made banking safe; this is Know Your Agent.
Registries compound (Delaware / D-U-N-S / LEI dynamics, at API speed) · neutrality — platform IAM dies at the tenant edge and payment networks won't trust each other's attestations, so the standing layer structurally wants an open standard · years of formation-semantics depth · two-sided lock-in: the human ventures the formation product wins are the accountability anchors the agent product needs.
