B2B Company Data Enrichment and Contact Emails | DataMerge

# DataMerge > B2B Company and Contact Data Enrichment Platform DataMerge enriches company and contact data for B2B sales and marketing. Given a company domain, it returns the actual **legal entity** registered to that domain — including official legal name, registered address, jurisdiction, and position in the **corporate hierarchy**. For multinationals, you can retrieve any entity in the corporate tree: the country-level subsidiary, the regional parent, or the global ultimate holding company. DataMerge also finds and enriches contacts at companies (emails, phones, LinkedIn). Covers 375M+ companies globally. **API base URL:** `https://api.datamerge.ai` **Free trial:** 20 credits on signup — no credit card required.
