# The 30 largest corporate groups and holding companies in Johannesburg

Tamtam tracks 37 corporate groups and holding companies headquartered in Johannesburg. This list ranks the 30 largest by number of employees on LinkedIn, led by Standard Bank Group, Eskom Holdings SOC Ltd and MTN. Their median headcount is 2,671. Half of them were founded in 1977 or later.

The companies listed are large corporate groups and holding companies headquartered in Johannesburg, primarily operating in financial services, telecommunications, and utilities. These include established entities like Standard Bank Group, a financial services provider, and Eskom Holdings SOC Ltd, a power utility. MTN is a pan-African mobile operator, and Absa Group focuses on financial services.

A notable pattern is the concentration of financial services firms, alongside major infrastructure and utility providers.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
