Comgy

Comgy is a Berlin-based proptech company founded in 2017, specialising in the collection, management, and analysis of building energy consumption data for residential real estate. The company provides an energy data operating system that digitises the measurement, visualisation, and billing of heat, water, and electricity consumption across large property portfolios. Its IoT-enabled smart submetering platform replaces legacy manual meter-reading processes with automated, real-time monitoring, helping asset managers and housing companies comply with EU energy efficiency directives including the amended Energy Efficiency Directive (EED). Comgy's technology covers the full value chain from raw data collection to actionable energy insights. The company raised €25 million in a Series B round in 2021, led by Rivus Capital (part of P&P Group), with participation from German energy provider EWE. CEO Rytis Jakubauskas represented Comgy as a finalist in the ABB Startup Challenge 2025, and the company was recognised by the Startup Energy Transition initiative for its demand-side innovation in decarbonising the building sector. In 2025, Comgy was acquired by advizeo, a greentech subsidiary of Hager Group, one of the global leaders in electrical building services. The acquisition combines advizeo's energy management SaaS platforms with Comgy's metering infrastructure, creating a fully integrated offering for building energy performance in Germany and across Europe. Comgy employs between 51 and 200 people and is headquartered in Berlin, serving real estate portfolios throughout Germany.
