# Top 47 manufacturers in St. Gallen

Tamtam tracks 47 manufacturers headquartered in St. Gallen. This list ranks all of them by number of employees on LinkedIn, led by Bühler Group, Geberit and SFS Group. Their median headcount is 150. Half of them were founded in 1963 or later.

The manufacturers in St. Gallen canton are primarily established industrial firms, many with a long history. They specialize in diverse fields from machinery and electronics to specialized components and materials. Bühler Group, founded in 1860, develops process solutions for food and vehicle manufacturing. Geberit specializes in sanitary technology, while SFS Group supplies precision components and fastening systems. Leica Geosystems provides precise measurement instruments.

A notable pattern is the concentration of headquarters in specific towns within the canton, such as Heerbrugg, Uzwil, and Rapperswil-Jona. The companies include both large groups like Bühler and more specialized mid-sized firms such as Cicor Group, which offers full-cycle electronic solutions, and BUCHI Laboratory Equipment, focused on laboratory technology.

## 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.
