Knowing who owns a company helps to understand its connections and operations. Our corporate hierarchy data allows you to follow the links between parent companies, subsidiaries, and shareholders. This shows control, organization, and risk in any global group. Whether assessing Willis Towers Watson or another multinational, this insight supports compliance checks, market research, and better CRM data management. With verified ownership records for over 380 million companies worldwide, CompanyData.com gives a clear picture of corporate ownership across industries and countries.

Each entity is assigned a unique ID so you can connect subsidiaries to their parent companies, track ownership and integrate this data within your own systems.
Control is determined through ownership stakes. We consider companies as controlled subsidiaries when ownership exceeds 50%. This focus on majority-held subsidiaries clearly shows corporate hierarchies. The same method applies for Willis Towers Watson and other multi-country groups.
