What The Warren Group does

The Warren Group is a fourth-generation, family-owned data solutions company headquartered in Peabody, Massachusetts, with operating roots tracing to 1872. The company provides national real estate and mortgage data covering 155+ million properties, 157+ million land parcel records, 183+ million building footprints, and 340+ million building permits, with 33 years of transaction history in New England and 15 years nationwide. Core offerings include Data Licensing, a Property Data API (JSON/XML) covering 150+ million properties, AI-Ready Data for machine learning integration, a Bulk Automated Valuation Model (AVM) with confidence scores, and analytics modules including Warren Analytics, Mortgage MarketShare, Loan Originator Module, Portfolio Analysis Reporting (PAR), Match & Append, Red Flag Alerts, and Marketing Lists.

The business runs on a multi-revenue model: enterprise data licensing and royalties (multi-year contracts, custom-priced), recurring subscriptions (publications Banker & Tradesman, Commercial Record, Registry Review; RERS Professional; API access), data monetization through marketing lists and Warren Lead Stream, and professional services for custom research and document retrieval. Distribution combines direct enterprise sales, a longstanding reseller/VAR program, technology partner/OEM distribution through Snowflake, BigQuery, Databricks, Amplify, and Syniti, and self-service e-commerce for smaller subscriptions.

Customers span real estate professionals, mortgage lenders and banks, finance professionals, the insurance industry (including a disclosed Cytora partnership for commercial underwriting), legal professionals, PropTech companies, home services, universities, and government/municipalities. The company has executed a deliberate strategic refocus: in 2018 it sold its Event Production and Custom Publications Divisions to American Business Media and relocated to Peabody, and in 2019 it expanded from regional New England coverage to nationwide data, described internally as the biggest shift in its 150-year history. The fifth generation of the Warren family joined the board in 2021.
