Where the company descriptions come from
RevenueBase compiles company information from public sources, including company websites and public professional profiles such as LinkedIn, alongside information supplied by companies. The short recorded excerpt shown here is separate from the complete business description used for matching; individual source URLs and collection dates are not provided in this public snapshot.

86% good or better at Exact
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. It reports 86% of Exact matches judged good or better, and 77% for a 240-pair sample of one- or two-word categories. This evaluates the method across study queries rather than auditing this individual list.
