What qualifies: Company records associated with Sao Paulo, Brazil whose business descriptions match “water treatment companies” by meaning at the Exact setting.

This saved list uses Exact. Each row's Exact match badge shows inclusion in that search, not an individual score or a service-quality judgment.

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.
