# 26 leading corporate groups and holding companies in Gelderland

Tamtam tracks 26 corporate groups and holding companies headquartered in Gelderland. This list ranks all of them by number of employees on LinkedIn, led by Alliander, TenneT and Unica. Their median headcount is 394. Half of them were founded in 1959 or later. The most common headquarters are Ede (5), Apeldoorn (4) and Arnhem (3).

This selection of corporate groups in Gelderland includes several larger mid-sized firms and some younger companies. Many operate in utilities and infrastructure, such as Alliander, an energy network company, and TenneT, a European grid operator. Others focus on technical services like Unica, or specialized manufacturing such as BDR Thermea Group, which supplies sustainable heating technologies.

A notable pattern is the concentration of companies in specific cities. Arnhem hosts several large entities in utilities and insurance, including Coöperatie VGZ. Ede is home to multiple firms in animal feed manufacturing and education, like Royal De Heus and Aeres. Apeldoorn shows a mix of sectors, from farming with Royal Agrifirm Group to automotive with Dusseldorp.

## 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.
