Built AI is an AI-native operating system for institutional real estate that unifies data from Argus, Yardi, MRI, Excel, and lease documents into a single knowledge graph, then runs it through a deterministic calculation engine so every number in every output can be traced back to its source. A catalog of named AI agents, covering deal underwriting, lease abstraction, covenant monitoring, close reconciliation, investor letters, and variance explanation, drafts work on that graph and pauses for human approval before anything leaves the client’s tenant. Founded in 2020 and in production since 2023, Built AI serves REITs, owner-operators, PE sponsors, and fund managers including Howard Hughes Holdings and CBRE, and reports zero autonomous external actions across its client base.
