What Brunata A/S does
Brunata A/S is a Danish cleantech company founded in 1916 and headquartered in Herlev, Denmark, that provides IoT-based smart metering and consumption-management services for residential buildings, housing associations, property administrators, and water utilities. Its core offering combines electronic heat cost allocators, ultrasonic energy and water meters, and a growing portfolio of indoor-climate, leak, running-toilet, and smoke-alarm sensors, all connected over LoRaWAN or Wireless M-Bus networks into the B.One digital ecosystem. The B.One brand unifies the Brunata Online platform, the Energy Management System (EMS) for cross-property monitoring, the MyBrunata resident app, and the Smart Building services layer; meter hardware is sourced from German sister company ZENNER (IUWS, Zelsius C5, Minometer M8 lines) and certified to MID and DVGW standards with up to 15-year battery life. Brunata generates revenue through a mix of recurring multi-year consumption-reporting subscriptions, hardware sales via the shop.brunata.dk storefront and direct enterprise channels, EMS and Smart Building service subscriptions, and the bundled Brunata All-in-One subscription. The Danish entity reported 392.2 million DKK in revenue and 84.9 million DKK in operating profit for FY2025, with the firm operating 15 wholly-owned European subsidiaries across Austria, Belgium, Croatia, Estonia, France, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Norway, Poland, Slovenia, Sweden, and Switzerland. GTM is sales-led B2B, combining direct enterprise field sales for housing associations and water utilities, inside sales for mid-market property administrators, and a self-serve e-commerce shop, supplemented by trade fairs, EED-compliance content marketing, and a co-produced podcast with industry body EjendomDanmark.
