OpenCorporates
opencorporates.com
The largest open database of companies worldwide, aggregating corporate registry data from over 140 jurisdictions into one searchable index.
OpenCorporates structures records from official company registries across the globe into a clean, searchable platform. It maps corporate hierarchies, active regulatory histories, and incorporation filings — making it a primary tool for journalists, investigators, and researchers tracing business relationships.
Why it is useful
Official business registries are fragmented across hundreds of regional portals, many behind paywalls or with unusable search interfaces. OpenCorporates aggregates over 200 million company records under one API and search layer — making it an essential resource for anyone doing open-source corporate intelligence.
