What Grether + Schäfer does
Grether + Schäfer AG is a privately held Swiss engineering firm (Aktiengesellschaft) based in Gelterkinden, Basel-Landschaft, specializing in the integral planning of building technology systems covering heating, ventilation, and cooling (HLK/Heizung, Lüftung, Kühlung). Founded in 1980 and operating with a team of five including owner Marco Gysin, the firm offers a modular service portfolio spanning feasibility studies, energy certifications (Energienachweise), cooling load calculations, tender documentation, specialist coordination, subsidy applications, execution planning, site management (Fachbauleitungen), solar planning, and general specialist planning for heating replacement projects. Its work is grounded in Swiss regulatory frameworks, including Minergie standards and renewable energy affiliations (Holzenergie, Swisssolar, ProPellets, FWS, Suissetec).
The company serves public and private clients across education and sports facilities, residential developments, commercial and industrial buildings, retail (notably Coop and Migros locations), and healthcare/care facilities, with a regional concentration in the Basel-Landschaft and adjacent Fricktal area. Revenue is generated through project-based professional services engagements with individually negotiated fees and multi-year contract cadences, supported by direct client engagement rather than channel partnerships. The reference portfolio includes municipal schools, gymnasiums and swimming pools in Gelterkinden and surrounding municipalities, retail modernizations for Coop and Migros, retirement and nursing homes, and renovations of buildings for the Salvation Army and other institutional clients.
The business is owner-operated and family-influenced (Gysin family members in ownership, accounting, and heating project management), with no disclosed institutional investors, funding rounds, parent company, or M&A activity. Operating geographies are explicitly regional rather than national or international, and the firm relies on a professional website as its primary external marketing surface rather than active digital channels, paid acquisition, or partnerships.
