# Top 50 companies with a mobile app in Lower Saxony

Tamtam tracks 54 companies with a mobile app headquartered in Lower Saxony. This list ranks the 50 largest by number of employees on LinkedIn, led by Volkswagen Group, TUI and KKH Kaufmännische Krankenkasse. Their median headcount is 286. Half of them were founded in 1934 or later. The most common headquarters are Hanover (16), Oldenburg (3) and Osnabrück (3).

These companies are the largest employers in Niedersachsen with a mobile app. The list includes large, established firms, mostly in the automotive, insurance, and tourism sectors. Volkswagen Group, for instance, designs and sells cars globally, while TUI is a global travel and leisure company. KKH Kaufmännische Krankenkasse provides statutory health insurance.

A notable pattern is the concentration of headquarters in Hannover, which hosts companies such as enercity, an energy service provider, and VGH Versicherungen, the largest insurer in Niedersachsen. This indicates a strong economic hub in the state capital, complemented by other significant companies like Oldenburgische Landesbank AG in Oldenburg.

## 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.
