Experian's US credit business began as TRW Information Systems. In 1996 TRW sold it to Bain Capital and Thomas H. Lee, who renamed it Experian and sold it that November to the British retailer GUS, which merged it with its own credit business. The group was spun off and listed in London as Experian plc in 2006. The US credit file sits with Experian Information Solutions, Inc., the FCRA-regulated part most people have dealt with.
What makes Experian a data broker is Experian Marketing Solutions, LLC, one of its business-to-business lines. Its Consumer View product profiles US households with more than 5,000 attributes, and Experian's own notice lists age, gender, marital status, income, occupation, education, household makeup, political affiliation, device identifiers and location among them. It builds them from tax assessor and deed files, surveys, telephone directories, subscriptions, the Census, online and app activity, retail purchase history and other data providers. Mosaic then sorts every US household into one of 19 groups and 70 types.
Experian owns two more data businesses that file or answer separately. It completed its acquisition of Tapad, a digital identity-resolution company that links devices, cookies and ad IDs, in November 2020, and completed its purchase of AtData, the email-intelligence company, on 18 February 2026 for $225 million.
