# Corporate groups and holding companies headquartered in the Netherlands Tamtam tracks 235 corporate groups and holding companies headquartered in the Netherlands.

The most common headquarters are Utrecht (7), Rotterdam (4) and Arnhem (3). This selection of corporate groups and holding companies in the Netherlands includes major players in various sectors. Among them are Nederlandse Spoorwegen, a key public transportation provider; Prosus, a global consumer internet group; Alliander, an energy network company distributing gas and electricity; and VDL Groep, an international industrial company.

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.
