Retrieve the UBOs of a company

Identify the Ultimate Beneficial Owners (UBOs) - the natural persons who ultimately own or control a company. This endpoint calculates beneficial ownership by traversing the complete ownership chain, including indirect ownership through multiple corporate layers. Cost: 25 credits

​
What are UBOs?

Ultimate Beneficial Owners are the natural persons who ultimately own or control a company through direct or indirect ownership. According to German law (GwG - Geldwäschegesetz), individuals holding more than 25% of shares or voting rights are typically considered beneficial owners. Our API automatically calculates these percentages by analyzing multi-level ownership structures. UBO analysis is currently available for:
  • GmbH - Limited liability company
  • gGmbH - Non-profit limited liability company
  • UG - Entrepreneurial company (mini-GmbH)
  • KG - Limited partnership

​
Use Cases

AML/KYC Compliance: Financial institutions, lawyers, and notaries use UBO data to fulfill anti-money laundering and know-your-customer requirements. Identify who ultimately controls a business relationship. Enhanced Due Diligence: For high-risk transactions, identify the natural persons who ultimately benefit from and control the company, even when ownership is structured through complex corporate arrangements. Regulatory Reporting: Many industries require disclosure of beneficial ownership. Use this endpoint to automatically identify reportable UBOs for regulatory filings and transparency registers.
