Tamtam tracks 29 companies with in-house R&D headquartered in Limburg. This list ranks all of them by number of employees on LinkedIn, led by DSM, QIAGEN and Maastricht UMC+.

These Limburg companies with in-house R&D are primarily large and mid-sized firms, with a focus on chemical manufacturing, healthcare, and specialized industrial production. DSM, with over 12,000 employees, is a global leader in bioscience for health and nutrition. QIAGEN provides "Sample to Insight" solutions for healthcare and research, while Maastricht UMC+ is an academic hospital. Canon Production Printing develops high-tech printers, and Inalfa Roof Systems Group produces roof systems for the automotive industry.

## 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.
