What myWarm does
myWarm GmbH is a Vienna-headquartered climate-tech company founded in 2010 that develops and delivers AI-driven heating and cooling optimization solutions for existing buildings. Its core technology is a patented, temperature-based hydraulic balancing method — protected by a 2011 European patent — that uses real-time sensor data and a proprietary Bayesian algorithm trained on over 13.8 billion temperature data points to dynamically optimize flow rates, supply temperatures, and pump performance. The product portfolio is organized around the integrated myWarm Optimize platform (Optimize-Control, Optimize-Balance, Optimize-Comfort), supplemented by standalone offerings including myWarm Balance (temperature-based hydraulic balancing), myWarm Balance-Cool (extension to water-based cooling systems for data centers and laboratories), Fernwärme-Check (district heating connection analysis), and Wärmepumpen-Ready (heat pump readiness assessment). The company has optimized more than 200,000 heating and cooling surfaces across Germany and Austria, with documented energy savings of up to 35% (top performers) and ~18% on average, compared to a branch average of 7–12%.
myWarm operates a B2B enterprise sales model targeting property companies, housing associations, public-sector entities, commercial building operators, healthcare facilities, and data centers. Revenue is generated through a mix of one-time professional services engagements (priced per adjustment point for hydraulic balancing) and multi-year subscription contracts (Optimize-Control at EUR 13,000–16,000 over 10 years for a typical installation). The company is a 100% subsidiary of Brunata-Metrona GmbH & Co. KG Munich since 2023, while operating as an independent brand with offices in Vienna (HQ), Berlin (myWarm Deutschland GmbH), and Munich (parent). Leadership comprises Dr. Klaus Hense (Managing Director, Austria), Daniel Kessler (Managing Director, Germany), and Stefan Fröb (Head of Sales), supported by a team of 23 employees. Regulatory endorsements from BAFA and KfW, plus GEG-compliant documentation, position the offering as subsidy-eligible for property owners across Germany and Austria.

myWarm competitors and assessment
Company assessmentDirect peers
- Kieback&Peter: German specialist in building automation and HVAC control systems. Comparable because Kieback&Peter provides building management systems and HVAC controls for commercial and public buildings — directly adjacent to myWarm Optimize-Control and a potential substitute for the digital heating cellar offering.
- Zenner: German metering and IoT/building-services provider. Comparable because Zenner sells submetering, energy-data, and HVAC-related services to housing companies and property managers in DACH, increasingly bundling heating optimization and energy efficiency offerings.
- ista: Global leader in submetering and energy services for buildings, with deep presence in Germany. Comparable because ista sells energy-data and building-efficiency services to the same housing-company and property-management segments and increasingly positions itself on heating optimization and CO2 reporting.
- Sauter: Swiss-German BMS and HVAC controls manufacturer. Comparable because Sauter provides building automation and HVAC optimization solutions for non-residential buildings, overlapping with myWarm Optimize-Control in commercial and public-sector customer segments.
- Techem: Major German provider of heating cost allocation, metering, and energy services to residential property companies. Comparable because Techem sells bundled energy-data and consumption-optimization services into the same housing-association and property-manager customer base that myWarm targets, and is expanding into heating optimization.
Broad incumbents
- Danfoss: Global HVAC controls and district-energy component supplier. Comparable because Danfoss produces the underlying valves, actuators, and controls that myWarm commissions, and increasingly offers software-driven optimization and district-heating solutions that compete with Optimize-Control and Fernwärme-Check.
- Bosch Thermotechnology: Broad incumbent heating and hot-water solutions provider. Comparable because Bosch sells heating systems, controls, and connected services into the same residential and commercial property segments and could integrate optimization services that substitute for myWarm's offering.
- Viessmann: Major German heating-system manufacturer covering boilers, heat pumps, and connected HVAC. Comparable because Viessmann is moving into service-driven heating optimization and digital controls, competing for the same property-owner wallet that myWarm addresses, and increasingly bundling AI-driven optimization with hardware.
- Brunata-Metrona: Parent company of myWarm and a large German energy services and metering provider. Directly comparable because it operates in the same DACH building-energy-services market, sells to overlapping housing-company and property-manager customers, and increasingly bundles energy optimization with metering.
Emerging players
- Stulz: Specialist in data center cooling and humidity control. Comparable because Stulz is the incumbent supplier of precision cooling to data centers — directly competing with myWarm Balance-Cool as a more established player in this vertical.
