Copenhagen's public sector is dominated by large institutions in healthcare, education, and culture. Notable entities include Københavns Universitet, the largest research and education institution in Denmark, Rigshospitalet, a specialized hospital, and DR - Danmarks Radio, a major media company. Other key organizations are HOFOR, a utility provider, and Det Kongelige Teater, the national theater.
These public sector organizations are primarily long-established institutions, with many founded centuries ago, such as the University of Copenhagen (1479) and Rigshospitalet (1756). This indicates a deep-rooted and stable public infrastructure in the city, with a strong emphasis on foundational services and cultural preservation.

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.
