CRE, finally online.
PropertyBus is open infrastructure for commercial real estate: a shared data layer for properties, spaces, tenants, plans, media, listings, and the AI systems that need to understand them.
// Not another portal. A common language for property data.
// (Yes, the bus pun is intentional. We're committed.)
Commercial real estate still runs on scattered PDFs, stale spreadsheets, locked portals, copied plans, fragmented tenant lists, and relationships trapped in private inboxes.
Every team rebuilds the same pipelines. Every property is described five different ways. Every AI system that touches CRE has to relearn the basics from scratch.
The commercial real estate internet should have better rails.
A property graph that brokers can use, developers can build on, and AI agents can understand — built in public where it matters, productized where it helps.
Properties, spaces, tenants, leases, media — defined once, used everywhere.
Move records out of locked portals into structured, interoperable form.
An open annotation format for floorplans, suite boundaries, and parcels.
Standard mappings so spreadsheets stop being a one-way data grave.
A defined shape for scraped property data — comparable across sources.
Property records that AI agents can actually read, query, and reason over.
PropertyBus.org is the open-source side of the project — a nonprofit foundation. Its job is simple: keep the schemas, formats, and reference implementations open, neutral, and useful to the entire ecosystem.
If you ship code, list space, sign leases, publish data, plan cities, or build AI for this industry — you belong on the early list.
