Corporate family tree
Knowing who owns whom is important to understand how companies connect and operate globally. Our corporate hierarchy data allows you to track links between parent companies, subsidiaries, and shareholders, showing the structure and control within any global group. Whether you are exploring Thomson Reuters or another multinational, this insight supports compliance checks, market research, and better CRM data management. With verified ownership details covering over 380 million companies worldwide, CompanyData.com gives you a clear picture of company relationships across industries and countries.
CompanyData.com maps each company profile – such as Thomson Reuters – using a three-level structure: Global, National, and Local headquarters. This reveals how every company fits into its overall corporate group.
Each entity has a unique ID, making it easier to connect subsidiaries to parent companies, follow ownership links, and integrate data into your systems.
Control is shown by ownership share percentage. When one company holds over 50% of another, it is classified as a controlled subsidiary. We focus on these majority-owned relations to clearly show corporate families. This method gives a clear view of complex groups like Thomson Reuters and can be used for any large multinational corporation.
This structure helps you pinpoint who makes the main decisions within the Thomson Reuters group, simplifies compliance reviews, and aids in mergers, acquisitions, or risk assessments. Mapping verified ownership across companies allows CompanyData.com users to understand Thomson Reuters’ global corporate setup. With data on over 41 million companies in 200 countries and territories, our platform helps international teams navigate complex company networks with confidence.
CompanyData.com supports global organizations that need verified insights into corporate ownership structures, from CRM enrichment and compliance workflows to market intelligence and analytics. We provide free evaluation samples; larger data samples (for example, up to 1,000 companies) are available to qualified corporate buyers with a defined use case and an active company website. If your primary need is contact or lead lists, please visit our Company Data Platform instead.
Tell us about your use case or data challenge, and our team will send you a tailored ownership data sample within 24 hours.
