Tamtam tracks 44 research institutes headquartered in Norway. This list ranks all of them by number of employees on LinkedIn, led by Norwegian University of Science and Technology (NTNU), Oslo University Hospital and University of Oslo. Their median headcount is 634. Half of them were founded in 1958 or later. The most common headquarters are Oslo (13), Trondheim (7) and Bergen (6).
These Norwegian research institutes are predominantly large universities and university hospitals. Notable examples include the Norwegian University of Science and Technology (NTNU) in Trondheim, which specializes in technology and natural sciences, and Oslo University Hospital, Norway's largest hospital.

## 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.
