Verified business data, not just a record count
This database holds 5,303,370 Spanish legal entities, each tied back to Registro Mercantil Central, then enriched with what a raw register leaves out: verified contacts, revenue, employee counts, and full corporate ownership.
A legal-entity database gives you the shell of a company; a mailing list gives you a contact with no context. Here both sit on the same record, so a business is not just a name and a registration number but a reachable, sized, owned entity you can qualify. Take it as a filtered Excel or CSV, a live API feed into a CRM or KYC flow, or a list you build yourself in the platform.
