How similarity works

Source
The RevenueBase company graph: 60 million companies and 398.9 million professional contacts resolved from primary sources, queried with RevenueBase Smart Search, the natural-language company search available to every RevenueBase user.
Matching
Companies are matched on what they actually do, as described in their own business descriptions, never on shared industry codes. The list keeps only matches at 85%+ measured similarity to Folderly INC, and match quality is audited by blind human judging. Read the full methodology.
Ranking
Team size, largest first, among the matched companies: companies are ordered by the number of professionals RevenueBase tracks at each one. Each row also shows its measured similarity to Folderly INC as a percentage.
Verification
Contact records re-verify on a rolling cadence rather than being scraped once and left to decay; each contact's own verification date is shown inside RevenueBase.
Refresh
This page's figures were pulled from the company graph on October 30, 2026. Lists refresh periodically as the graph is re-checked.
