# Top 100 companies with in-house R&D in Germany

Tamtam tracks 2,450 companies with in-house R&D headquartered in Germany. This list ranks the 100 largest by number of employees on LinkedIn, led by Siemens, Bosch and SAP. Their median headcount is 17,713. Half of them were founded in 1914 or later. The most common headquarters are Munich (10), Berlin (7) and Stuttgart (5).

These German companies with in-house R&D are primarily large, established groups across diverse sectors. Key industries include manufacturing, particularly motor vehicles and automation, software development, chemicals, and healthcare. Notable examples are Siemens, a technology company focused on industry, infrastructure, transport, and healthcare, and Bosch, a global supplier of technology and services. SAP provides enterprise applications and business AI solutions, while Fresenius Medical Care is a global leader in renal disease products and services. Volkswagen Group designs, manufactures, and sells cars globally, and Bayer is a life science company focused on healthcare and nutrition.

A significant pattern in these companies is their long history; many were founded in the 19th or early 20th century, such as Siemens (1847), BASF (1865), and Continental (1871). This indicates a strong foundation of traditional industrial and technological development. Headquarters are distributed across Germany, with notable concentrations in cities like Munich, Wolfsburg, and Leverkusen, reflecting a broad geographical spread of industrial activity.

## 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.
