vilisto GmbH

What vilisto GmbH does

vilisto GmbH is a Hamburg-based climate-tech company founded in 2016 that builds a digital heat-management system for non-residential buildings (offices, public-sector buildings, schools, universities, and protected monuments). The platform addresses a specific inefficiency: most rooms in these buildings are unoccupied up to 80% of the time yet continuously heated, and conventional measures (night setback, insulation, boiler replacement) do not account for actual usage patterns. vilisto's response is a three-component stack — vilisto.thermo (self-learning radiator thermostats with patented three-sensor presence detection using motion, sound, and light), vilisto.insight (a cloud-based monitoring platform with real-time temperature, humidity, and consumption analytics), and vilisto.balance (TÜV-certified adaptive hydraulic balancing delivered as software on top of the same hardware). The system is marketed exclusively B2B and B2G, with reported heating-cost and CO2 savings of up to 32% (case-study range 17–32.5%), and is eligible for German federal BEG subsidies (15%).

Revenue mechanics blend hardware (thermostat sale or rental), recurring platform subscriptions for vilisto.insight, professional installation services, and increasingly software-defined offerings such as VEM (energy/savings monitor) and vilisto.balance. The go-to-market is sales-led direct, with consultation, savings analysis, project management, and a partner program for sales and installation resellers; marketing relies on content, webinars, PR via bitkom, and ESG/sustainability messaging. By 2025 the company reports 300+ (some pages 400+) customers across German municipalities (Stadt Berlin, Hamburg, Koblenz, Hildesheim, Konstanz, etc.), corporates (Berliner Volksbank, ENGIE, DB InfraGO, AOK, EUROPA-CENTER), real estate (Volkswagen Immobilien, S-Immobilien, CLS Holdings), and education (Goethe-Universität Frankfurt), with cumulative reported CO2 savings of 29,788 tonnes. The company has €5M Series A funding from SET Ventures and E.R. Capital Holding (July 2023) and a patent on its presence-detection technology, with European expansion underway.

Core offering

vilisto GmbH develops and sells a digital heat management system for non-residential buildings, anchored by self-learning, presence-detecting radiator thermostats (vilisto.thermo) with integrated 3-sensor technology (motion, sound, light). The offering is complemented by a cloud-based online monitoring and analytics platform (vilisto.insight) and TÜV-certified adaptive hydraulic balancing software (vilisto.balance), delivered with installation services to German municipalities, enterprises, and real estate operators.

Product overview

vilisto GmbH offers a modular digital heat management system for non-residential buildings. The core portfolio consists of three integrated components: (1) vilisto.thermo — the self-learning, presence-detecting smart radiator thermostat (now in its 4th generation) that automates heating based on learned occupancy patterns; (2) vilisto.insight — the online monitoring and analytics platform providing real-time visibility into temperature, energy consumption, and savings; and (3) vilisto.balance — an adaptive hydraulic balancing software feature that optimizes heat distribution through the existing thermostat infrastructure. Together, these products deliver up to 32% heating cost and CO₂ savings without building modifications. The system is marketed exclusively B2B/B2G and serves offices, public buildings, educational institutions, and protected monuments across Germany.

Comparable to vilisto as a commercial HVAC-controls incumbent, but operating at portfolio-BMS scale across many verticals rather than specializing in self-learning radiator thermostats for non-residential heat optimization.
• Bosch Thermotechnology: Bosch Thermotechnology manufactures heating systems and connected controls (e.g., Bosch EasyControl) for residential and light commercial use. Comparable to vilisto on connected heating-control hardware, but distributed as part of a much wider HVAC portfolio and not focused on AI-driven, presence-detecting radiator valves for office and public-building retrofits.
• Danfoss Climate Solutions: Danfoss is a leading supplier of hydronic heating controls, balancing valves, and electronic radiator thermostats widely used in commercial buildings. It is highly comparable to vilisto on commercial hydronic control infrastructure and directly intersects with the vilisto.balance adaptive hydraulic balancing functionality.
• Schneider Electric (EcoStruxure): Schneider Electric's EcoStruxure platform offers building management, HVAC control, and energy optimization across commercial real estate. As a broad incumbent, it competes with vilisto for enterprise facility managers looking to digitize energy performance, though it bundles many capabilities beyond heat-specific radiator automation.
• Viessmann Climate Solutions: Viessmann Climate Solutions (recently carved out with Carrier) provides heating systems and digital control products for residential and commercial buildings in Europe. Comparable to vilisto on connected commercial heating, though positioned upstream as a boiler/heat-pump + controls vendor rather than a retrofittable radiator thermostat specialist.

Others

• synavision: synavision provides analytics and ESG-compliant building optimization software used to plan and verify energy-efficiency measures in commercial real estate. It is a complementary/partnering vendor to vilisto (the two announced a strategic partnership in October 2025) rather than a competitor, addressing analysis-and-reporting layers of the same building decarbonization workflow.
