ATTOM Data Solutions

ATTOM Data Solutions

ATTOM Data Solutions was founded in 2003 by a group of real estate data and technology professionals, growing through the housing cycle to become a central aggregator of public property records. The firm's database integrates tax assessments, sales history, mortgage liens, foreclosures, and neighborhood demographics, drawn from over 2,500 counties nationwide (public record). ATTOM's revenue model is primarily B2B licensing and subscription-based data feeds, API access, and analytics tools for clients including banks, insurers, appraisal firms, and hedge funds. The company also provides bulk data sets for automated valuation models and portfolio risk assessment, covering all 50 U.S. states. Known clients and integrations include CoreLogic affiliates, mortgage servicers, and property technology platforms (per industry reports, 2023). ATTOM Data Solutions has not publicly disclosed revenue, AUM, or team size. The firm operates primarily from its Irvine, California headquarters, with no additional known offices. In March 2024, ATTOM announced a partnership with a national mortgage data provider to expand its foreclosure and pre-foreclosure data coverage (per the firm, March 2024). Unlike many property data firms that focus on consumer-facing Zillow-style listings, ATTOM's structural differentiator is its emphasis on back-office, institutional-grade data — the raw records that drive automated valuation, tax appeal, and risk compliance. This positioning means ATTOM avoids the commoditized MLS-listing layer and sells directly to the institutional buyers of property intelligence.
