# 50 leading electronics and semiconductor companies in Baden-Württemberg

Tamtam tracks 62 electronics and semiconductor companies headquartered in Baden-Württemberg. This list ranks the 50 largest by number of employees on LinkedIn, led by Bosch, TRUMPF and SICK Sensor Intelligence. Their median headcount is 610. Half of them were founded in 1949 or later. The most common headquarters are Freiburg im Breisgau (3), Reutlingen (2) and Stuttgart (2).

These 15 companies in Baden-Württemberg are primarily involved in electronics, semiconductors, and related manufacturing for industrial and automotive applications. They range from large, established corporations like Bosch, a global supplier of technology and services, to specialized firms such as ZEISS Semiconductor Manufacturing Technology, which develops equipment for microchip production. TRUMPF is a provider of machine tools and laser technology, while Eberspächer Group specializes in automotive exhaust and climate control systems.

A common thread among many of these companies is their focus on industrial automation and automotive components. SICK Sensor Intelligence is a leader in sensor solutions, and Pepperl+Fuchs Group manufactures electronic sensors for factory automation. A notable pattern is the presence of several century-old companies, including TRUMPF (founded 1923), Eberspächer Group (1865), and CeramTec (1903), indicating a long-standing industrial tradition 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 12, 2026.
