What TSAB Thurnherr does

TSAB Thurnherr SA is a privately held Swiss software company (Société Anonyme) founded in 1951 by Gérard Thurnherr and headquartered across two complementary locations: Founex in Vaud (programming and management) and Bern (technical service and IT support). The company develops and distributes property management software for the Swiss market, serving rental property managers (gérances), condominium/strata (PPE) administrators, housing cooperatives, and self-managing property owners through the Immob and Osalis product families.

The product portfolio spans the legacy desktop suite Immob8.5 (PRO and SmallBusiness editions) and the modern web/cloud platform Immob10 (FIRST and PRO editions), complemented by Osalis for self-managing owners and supporting modules including e_mmob8 (owner portal) and GED (document management). Architecturally, the company layers a COBOL-based foundation—chosen explicitly for long-term stability and data compatibility—on top of modern web technologies (Angular 7, TypeScript 3.1, Java 10, Spring 5, Hibernate 5, Apache POI), with Osalis built on the Windev environment. The Immob10 platform represents the company's strategic transition toward cloud-native delivery while preserving the data continuity of its COBOL core.

Revenue is generated primarily through annual software maintenance contracts tied to license version and customer business volume, supplemented by training services (CHF 650 per full-day course, 10% multi-attendee discount), custom R&D and integration work, managed hosting, and IT services/hardware sales. Distribution is direct-sales-led, supported by telephone-based customer support, on-site and in-facility training, and a bilingual (French/German) field presence across Romandie and German-speaking Switzerland. With 15 personnel, no external institutional investors, and family-aligned leadership (director Jean-Jacques Thurnherr, son of the founder, with 50 years of company tenure), TSAB Thurnherr operates as a small, long-tenured, cash-funded niche vertical-software vendor focused exclusively on the Swiss property management market.
