Visit Reonomy Alternatives

Reonomy, now sold as "Reonomy, an Altus Group business," specializes in unmasking commercial property ownership, including properties held through LLCs and shell companies, and surfacing decision-makers for brokers, lenders and investors sourcing off-market deals. Its dataset spans more than 53 million U.S. properties with ownership records, transaction history, occupant information and predictive scores estimating a property's likelihood of selling. It is delivered as self-serve web software with monthly or annual subscriptions, plus bulk data feeds and API access for larger programs. Against CoStar's strength in verified lease and sale comps, Reonomy's differentiator is ownership resolution and prospecting, aimed more at deal origination than market-level trend analysis.
