# The 50 largest companies in Nijmegen

Tamtam tracks 120 companies headquartered in Nijmegen. This list ranks the 50 largest by number of employees on LinkedIn, led by Nexperia, Radboudumc and Radboud University. Their median headcount is 413. Half of them were founded in 1991 or later.

These are some of the largest organizations in Nijmegen, primarily active in healthcare, education, and specialized manufacturing. The list includes major employers like Nexperia, a global semiconductor company, Radboudumc, an academic medical center, and Radboud University, a research-focused public university. Other significant entities are Pluryn, specializing in youth care and disability support, and Gemeente Nijmegen, the municipal administration.

A notable characteristic of these organizations is their deep roots in the city, with many having headquarters in Nijmegen. The presence of multiple large healthcare providers such as Canisius Wilhelmina Ziekenhuis and Sint Maartenskliniek, alongside educational institutions, indicates a strong emphasis on public services and specialized knowledge-based industries in the 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 11, 2026.
