Knowing who owns and controls companies is essential to understanding how they operate globally. Our corporate hierarchy data helps reveal the links between parent companies, subsidiaries, and shareholders, showing the control and setup of any multinational group. Whether you’re studying Omnicom Group or another global company, this insight supports compliance procedures, market analysis, and better CRM management. With verified ownership data on over 380 million companies worldwide, CompanyData.com gives a clear picture of corporate structures across industries and countries.
At CompanyData.com, we map each company – including Omnicom Group – using a clear three-level hierarchy: Global, National, and Local headquarters. This system helps show how each part of the corporate family fits together.
Each entity carries a unique identifier, allowing users to track subsidiaries up to parent companies, trace ownership paths, and integrate data with internal systems.
Control is defined by ownership stakes. When a company owns over 50% of another, it is recorded as a controlled subsidiary. Our database focuses on these majority-owned entities to clearly map corporate hierarchies. This method provides a transparent view of complex structures such as Omnicom Group’s and can be applied universally.
This approach identifies key decision-makers within the Omnicom Group, simplifies legal compliance, and aids in risk management or merger and acquisition analysis. By mapping each entity with verified ownership links, CompanyData.com helps users confidently explore Omnicom’s global structure. With over 1,300 subsidiaries spanning 68 countries including the USA (415), Germany (151), Australia (63), Canada (37), China (38), France (58), and the UK (120), our platform provides clarity to complex international corporate frameworks.
CompanyData.com supports global companies looking for verified information on corporate structures and subsidiaries. From CRM enrichment and compliance tasks to market research and analytics, we offer precise and up-to-date data. Evaluation samples are free; larger datasets (for example, up to 1,000 companies) can be provided to qualified buyers with a clear use case and a valid company website.
