perto GmbH is a Berlin-based energy efficiency startup founded in 2016 by Sebastian Schröer. The company develops pertoIOTA, a smart, cloud-enabled Building Management System (BMS) that uses Internet of Things (IoT) sensors and artificial intelligence to monitor, control, and optimize energy systems in buildings, particularly heating and ventilation. The system is designed as a standardized, plug-and-play solution that can be deployed in any building type, with a primary focus on older and mid-sized properties that typically lack modern energy management infrastructure.
pertoIOTA works by connecting IoT sensors throughout a building to collect real-time data on temperature, energy consumption, and equipment performance. This data is transmitted to the cloud where AI algorithms analyze patterns and automatically optimize building operations. Key features include real-time monitoring, predictive maintenance, automated scheduling, and remote control of heating systems. The platform alerts building managers when equipment such as heating pumps operates below optimal efficiency, enabling proactive maintenance and reducing energy waste.
The company reports that its system can achieve energy savings of 15–50% along with corresponding reductions in CO₂ emissions. perto positions its offering as Efficiency as a Service (EaaS), making building decarbonization accessible and scalable without requiring major upfront capital investment. The company has been recognized in the energy innovation space, participating in the Start Up Energy Transition program and reaching the Smart Building Innovation World Cup at BIM World Munich in 2022. perto primarily serves property managers and building owners in Germany seeking to digitalize their operations and meet increasingly stringent energy efficiency requirements. The company is a member of the Solar Impulse Foundation's World Alliance for Efficient Solutions.
