Reonomy

A leading commercial real estate property intelligence platform operating as part of Altus Group, competing with CoStar, CompStak, and MSCI Real Assets in the CRE data space.

Reonomy is a commercial real estate (CRE) data and analytics platform that aggregates and analyzes property data, ownership records, debt information, and market signals to help real estate professionals identify opportunities and make informed decisions. Founded in 2013 and headquartered in New York City, Reonomy built one of the most comprehensive commercial property databases in the United States, covering millions of properties and leveraging machine learning to connect fragmented public records into actionable intelligence. Its platform serves brokers, lenders, investors, and service providers seeking to prospect, underwrite, and transact in commercial real estate markets. In November 2021, Altus Group — a leading provider of asset and fund intelligence for the global CRE industry — acquired Reonomy for approximately $200 million USD, integrating its data capabilities into Altus's broader analytics and software ecosystem. Under Altus Group ownership, Reonomy continues to operate as a distinct brand and product offering, enhancing Altus's data intelligence suite with deep property-level insights and ownership graph technology. The acquisition positioned Altus Group as a more formidable player in the CRE data market, competing directly with CoStar, MSCI Real Assets, and other data incumbents. While Reonomy is not traditionally classified as an AdTech company, its data infrastructure — particularly its property ownership and contact data — has significant relevance for targeted marketing, direct mail campaigns, and account-based outreach within the real estate vertical. Its ability to surface decision-maker contact information tied to specific properties makes it a valuable tool for data-driven prospecting and audience targeting in CRE-focused marketing workflows.
