Source: The RevenueBase company graph: 60 million companies and 398.9 million professional contacts resolved from primary sources, queried with RevenueBase SmartSearch, the natural-language company search available to every RevenueBase user.
What qualifies: Company records associated with Sao Paulo, Brazil whose business descriptions match “managed IT services for accounting firms” by meaning at the Exact setting.
