These St. Gallen companies with in-house R&D are primarily large, established firms in industrial manufacturing, specialized machinery, and technology. For instance, Bühler Group develops process solutions and manufacturing equipment, while Geberit specializes in sanitary technology. SFS Group supplies precision components, and Leica Geosystems provides precise measurement instruments. Kantonsspital St.Gallen is a leading hospital. The list also includes newer technology firms like Sportradar, a global sports technology firm, and INFICON, which provides instrumentation and sensor technologies.
The companies are mostly headquartered in various towns across the St. Gallen area, such as Uzwil, Rapperswil-Jona, Heerbrugg, and St. Gallen itself. This indicates a broad regional distribution rather than a single urban cluster for R&D activities.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
