Tamtam tracks 30 research institutes headquartered in South Africa. This list ranks all of them by number of employees on LinkedIn, led by University of Pretoria, University of Cape Town and University of South Africa/Universiteit van Suid-Afrika. Their median headcount is 1,177. Half of them were founded in 1981 or later. The most common headquarters are Pretoria (8), Cape Town (7) and Johannesburg (4).

These South African research institutes are primarily large higher education institutions. The University of Pretoria, with 12,260 employees, offers diverse postgraduate programs and focuses on research.

This indicates a hub for research and higher education in the capital region.

## 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 12, 2026.
