DEOS

What DEOS does

DEOS AG (DEOS Aktiengesellschaft) is a German manufacturer of building automation systems headquartered in Rheine, Germany, founded in 1968 and operating as the German arm of the Swedish Regin Group. The company designs, develops, and produces hardware and software for the automation and digitalization of non-residential buildings — offices, airports, hotels, schools, healthcare facilities, retail, industrial sites, and government infrastructure. Its portfolio spans OPEN-series DDC controllers (from compact OPEN 500/600 EMS units up to the high-density OPEN 4100 EMS), the B-AWS certified OPENweb and OPENweb Cloud building management software, OPEN FXL programming tools with reusable macro/template libraries, OPEN IO modules for 1:1 retrofit of competitor systems, and wireless LoRaWAN products including the battery-less DEOS TEO radiator thermostat and the DEOS SAM CO2 room air quality indicator. All core products are developed in-house and manufactured on the company's own SMD production line in Rheine, with the headquarters also serving as a live demonstration site since 2014.

DEOS monetizes through four revenue streams: hardware sales (DDC controllers, IO modules, sensors, thermostats, actuators), subscription/recurring revenue from building management software (OPENweb Cloud, Remote Service Portal), one-time license fees for programming tools and libraries, and professional services (consulting, project execution, maintenance, and training). Go-to-market is indirect: the company sells through a global network of 300+ certified system integrators who receive onboarding via easy-Startup, dedicated account management, and continuous training, while direct engagement for end customers and technical building equipment planners runs through the corporate website and regional Regin Group contacts. Customer evidence spans enterprise and public-sector logos including Berlin Brandenburg Airport, adidas, Amprion, Schwäbisch Hall, Kroma Tower, Antalya Airport, and Universitas Tanjungpura, indicating a diversified project portfolio across DACH, Benelux, Nordics, Southern Europe, and Southeast Asia. Certifications include B-AWS (for OPENweb) and BACnet Revision 1.26, with Regin Group parentage providing cross-border scale in product development and distribution.
