Tamtam tracks 99 companies with in-house R&D headquartered in the Czech Republic. This list ranks the 50 largest by number of employees on LinkedIn, led by ExxonMobil, Škoda Auto and Zentiva. Their median headcount is 633. Half of them were founded in 1971 or later. The most common headquarters are Prague (25) and Brno (5).

These companies with in-house R&D in the Czech Republic span several key sectors, including manufacturing, IT, and higher education. The list features a mix of very large corporations like ExxonMobil, which conducts pioneering research in energy, and established Czech entities such as Škoda Auto, known for designing and manufacturing vehicles. Other significant players include Zentiva, a pan-European pharmaceutical company, and Unicorn, an IT services provider.

A notable pattern among these organizations is the strong presence of academic institutions. Masarykova univerzita in Brno, along with Charles University and the Czech Technical University in Prague, represent a significant portion of the R&D landscape. Furthermore, many of these entities, such as Škoda Group in Plzeň, have long histories, indicating a tradition of innovation within the country.

## 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.
