# Build Holdco Agent

> Use when building an AdCP agency / holdco hub — one server hosting multiple specialism agents (governance + brand-rights + property-lists, etc.) with per-tenant data isolation. Distinct from skills/build-seller-agent/ (single-specialism) and decisioning-platform-multi-tenant.ts (host-routed tenancy).
