# 100 leading multinational companies in Norway
Tamtam tracks 556 multinational companies headquartered in Norway. This list ranks the 100 largest by number of employees on LinkedIn, led by Telenor, DNV and Aker Solutions. Their median headcount is 2,060. Half of them were founded in 1962 or later. The most common headquarters are Oslo (47), Stavanger (6) and Bergen (4).
These multinational companies in Norway represent a diverse mix of industries, with a notable presence of large established groups. Key sectors include oil and gas, telecommunications, and maritime services. For instance, Telenor is a major telecommunications provider, DNV specializes in risk management, and Aker Solutions offers integrated products for energy sectors. Equinor develops oil, gas, wind, and solar energy, while Yara International focuses on sustainable crop nutrition.
A significant pattern observed is the concentration of headquarters in Oslo, which hosts companies like Yara International, Norsk Hydro (aluminium production), DNB (financial services), and Schibsted (media and online marketplaces). Other prominent locations include Fornebu, home to Telenor and Aker Solutions, and Stavanger, where Equinor is based. The list features a blend of companies with deep historical roots, such as Norsk Hydro founded in 1905, and those established more recently.

## 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 11, 2026.
