Where company data comes from, how we refresh it, and how to use B2B exports lawfully.

Data sources

Company records come from public business registers: CEIDG, KRS, and REGON identifiers. We do not sell grey-market lists — every export is tied to a filter and an auditable order.

  • CEIDG — sole traders and contact data where publicly available
  • KRS — commercial companies
  • REGON — public statistics identifiers

Refresh and quality

The refresh pipeline validates records, deduplicates, and scores contact completeness. Product pages will show live counts; until production DB is connected, treat on-page counts as indicative.

Lawful use

Customers receive a license to use purchased data per terms and GDPR. Direct marketing requires your own legal basis and opt-out. We do not sell “pre-approved marketing consent” — we provide registry and public contact data.
