Notable examples include Nederlandse Spoorwegen (NS), which provides rail transportation, and Utrecht University, a prominent research-focused university. Other key organizations are HU University of Applied Sciences Utrecht, offering higher education, and ProRail, responsible for sustainable rail infrastructure.

## 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.
