Corporate family tree
Understanding ownership is key to seeing how companies connect and operate. Our corporate hierarchy data helps you trace relationships between parent companies, subsidiaries, and shareholders, revealing control, structure, and risks within any global group. Whether you’re analysing Telstra or another multinational, this insight supports compliance checks, market research, and better CRM data management. With verified ownership records covering millions of companies worldwide, CompanyData.com gives a clear picture of who owns who across industries and borders.
At CompanyData.com, each company profile — including Telstra — is mapped using a three-level hierarchy: Global, National, and Local headquarters. This system reveals how each entity fits in the larger corporate family.
Each company is assigned a unique ID, allowing you to connect subsidiaries to parent companies, track ownership paths, and link this data with your internal systems.
Control is determined by ownership. When a company owns more than 50% of another, it is classified as a controlled subsidiary. We focus on these majority-owned relationships to provide a clear view of corporate hierarchies. This method reveals the complex structure of companies like Telstra and can be applied to any multinational organization.
This mapping helps identify decision-makers within the Telstra Group, simplifies compliance checks, and supports merger and acquisition assessments or risk analysis. With verified ownership data from 294 subsidiaries spread over 17 countries, including Australia, United States, United Kingdom, Singapore, and India, CompanyData.com delivers transparency and clarity about Telstra’s structure to global teams navigating complex corporate networks.
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.
