I am using LeadMagic's "Enrich Company" enrichment, which returns the headcount, and I would like to know what their sources are.

LeadMagic uses their Company Finder API to gather headcount data, but the specific data sources aren't detailed in our documentation. [documentation The integration pulls from LeadMagic's database using company social URLs (like LinkedIn profiles) to retrieve employee count information. [clay.com For the exact data sources behind LeadMagic's headcount numbers, you'd need to check directly with LeadMagic at leadmagic.io or their API docs at documentation
