These Upper Austrian companies with in-house R&D are primarily established manufacturing firms, many with a long history, alongside significant contributions from the education sector. Companies like Fronius, founded in 1945, specialize in advanced power solutions, while TGW Logistics, established in 1969, focuses on automated fulfillment centers. Greiner, dating back to 1868, is a global supplier of plastics and foam solutions, and ENGEL, also founded in 1945, leads in injection moulding machines. The list also includes educational institutions such as Johannes Kepler Universität Linz and the University of Applied Sciences Upper Austria.
A notable pattern is the strong representation of industrial manufacturing, particularly in machinery and plastics, with a significant number of companies founded in the mid-20th century. For instance, KTM AG, founded in 1953, is a motor vehicle manufacturer. This concentration of mature manufacturing and academic institutions indicates a region with a deep-rooted industrial base and a focus on research and development.

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.
