metr is a Berlin-based proptech startup founded in 2016 that builds a universal IoT infrastructure for residential buildings, enabling data-driven facility management and accelerating the decarbonisation of real estate. The company's core product is an intelligent building management platform paired with the m-gate, a multifunctional IoT gateway that connects to heating systems, water infrastructure, and electricity meters regardless of manufacturer. metr's solutions span smart submetering, remote monitoring of heating and drinking water systems, digital heating optimisation, and smart metering — all integrated into a central platform that checks data for plausibility and visualises it for property managers. The company's digital heating optimisation technology enables energy savings of up to 35% in existing building stock without requiring construction work or physical renovation. metr has raised Series A funding of approximately $6.4 million and currently has around 33 employees. The platform is live in over 2,000 buildings, processing more than 15 million measurements. Notable customers include large German housing companies such as degewo and Stadtsiedlung Heilbronn. In October 2025, metr launched a crowdfunding campaign to expand its reach, highlighting the urgency of building-sector decarbonisation as heating costs rise and the EU strengthens its Buildings Directive. The startup complies with amended EED requirements for consumption transparency and positions itself as a manufacturer-independent solution for the housing industry's digital transformation.
