What Brunata Ag does

Brunata AG is a Swiss metering, billing, and IoT solutions provider headquartered in Sachseln, with additional offices in Regensdorf (Zürich) and Bern. The company sells and services meters for heat, water, and electricity, offering both wired (M-Bus) and wireless (LoRaWAN) data transmission options. Its core proprietary technology is the Switzercloud IoT platform, which aggregates sensor data from over 110 integrated devices and provides dashboards, anomaly notifications, and automated workflows, complemented by the Colibird end-user application for near-real-time visualization of sensor readings.

The company operates as the Swiss arm of the international Brunata-Minol-ZENNER Group, leveraging ZENNER's century-long metering expertise and the group's shared LoRaWAN infrastructure of over 30,000 gateways across Europe. Brunata generates revenue through a mix of hardware sales (meters from ZENNER and Optec/Herholdt), recurring subscription services (Switzercloud platform subscriptions, submetering/billing services), and professional services (installation and commissioning). Pricing is quote-based and project-specific, typically structured as multi-year contracts.

Brunata's primary customer segment is building owners and real estate companies requiring legally compliant heating and water cost allocation, with secondary segments including utility companies (channeled via esolva, which serves 200+ Swiss energy suppliers), municipalities/Smart City initiatives (e.g., Moosseedorf), facility management firms (Facility24), and trade/industry customers pursuing Industry 4.0 proof-of-concepts. Distribution combines a direct sales team with a network of sanitary, heating, and electrical installer partners across Switzerland.
