What qualifies
Company records associated with the United States whose business descriptions match “corporate board advisors” by meaning at the Exact setting.

Match quality
RevenueBase's August 25, 2026 study assessed 4,198 description/company pairs across matching settings. The publisher reports 86% good or better at Exact.
