What Ernst Fischer does

Ernst Fischer AG (trading as EFAG) is a privately-held, family-owned steel and metal construction company headquartered in Romanshorn, Thurgau, Switzerland, with its production operations on a site of over 6,000 m2. Founded in 1911 as a locksmith business and converted into a stock corporation (Aktiengesellschaft) in 1961, the company has been fully owned by the Gutjahr family since 2010; Diana Gutjahr serves as President of the Supervisory Board and Severin Gutjahr-Preisig as Delegate of the Supervisory Board. The business operates across three integrated service pillars: Stahlbau (custom steel construction — gas stations, industrial and commercial buildings, boat docks, football stadiums, special constructions), Metallbau (architectural metalwork — doors, gates, windows, glazing, stairs, railings, balconies, facades), and Service/Unterhalt (ongoing maintenance, repair, modernization, and condition assessment of steel and metal structures).

The company delivers projects through an in-house, end-to-end model spanning planning, design, manufacturing, and installation, with manufacturing concentrated at the Romanshorn facility using modern production technology. Named enterprise customers include ZSC Lions (ice hockey arena), SOCAR, BP, Shell, Esso, AVIA, and Coop (gas-station construction), Credit Suisse (commercial building), kybunpark/AFG Arena (football stadium), and Küry Park Side AG / Auto Lang (automotive retail). Headcount is reported at approximately 80-100 employees alongside a continuous apprenticeship program of roughly 10 metal-construction trainees.

Revenue is generated on a project-by-project basis across one-time steel and metal construction engagements, with an additional recurring revenue stream from service and maintenance contracts. The go-to-market is direct enterprise field sales, with projects delivered throughout Switzerland and internationally. The company maintains brand presence via its website, Facebook, Instagram, and LinkedIn, and pursues employer branding through a dedicated careers portal and apprenticeship program. Ernst Fischer AG is privately held with no subsidiaries, no institutional investors, and no public revenue disclosure.
