What Sauter does

Sauter is a privately held, family-controlled building automation group founded in 1910 and headquartered in Basel, Switzerland, under parent Fr. Sauter AG, with its main German operating entity Sauter-Cumulus GmbH based in Freiburg. The group employs approximately 2,200 people worldwide and operates through more than 19 wholly-owned subsidiaries plus a network of channel partners spanning Europe, the Middle East, Asia, and selected Pacific and Americas markets.

The company designs, manufactures, and integrates hardware and software for building and room automation, with a core technology stack built on the BACnet open protocol. Its product portfolio includes automation stations (modulo 6 / modu680-AS), room automation stations (ecos504/505), touch and button room control units (ecoUnit365, ecoUnit355), modular smart sensors (viaSens), and an integrated Smart Actuator that combines valve actuation, programmable automation, and IoT connectivity in a single device. Software and digital services span the SAUTER Cloud platform, SAUTER Vision Center (consolidated building data and energy visualization), Mobile Building Services (MBS) with the Mobile Room Control (MRC) app, the amanteia ESG/decarbonization platform, and the SAUTER Application Store launched in April 2026 for app-style distribution of pre-configured control applications.

Sauter monetizes through five streams: hardware sales of automation components, recurring software/cloud subscriptions, project engineering and commissioning services, facility management and managed services, and retrofit/modernization projects. Go-to-market combines direct enterprise field sales via local subsidiaries with technical sales engineers, channel partners (systems partners for integration and components partners for distribution), and education-led demand generation through the SAUTER Academy webinars. The company serves office, life science/healthcare, industrial, hotel, education, public-sector, retail, and logistics customers, with verifiable references including DLR Oberpfaffenhofen, Gemeinde Möglingen, NOVE Munich Arnulfpark, and Museum Island Berlin.
