Where Buildings, People, and Cities connect
At ProptechOS, our mission is simple: making buildings good inhabitants of the smart city. We believe cities of the future should be ecosystems where buildings, people, and infrastructure interact seamlessly.
Buildings are at the heart of this transformation. They are the world’s largest asset class, consume 40% of global energy, and generate one-third of greenhouse gases. By making them smart, we unlock sustainability, efficiency, and quality of life.
Who we are & what we do
ProptechOS was founded in 2019 by Erik Wallin and Per Karlberg, combining expertise from data science, engineering, and real estate. Built on the open-source standard RealEstateCore (REC), ProptechOS enables property owners to take full control of their data and transform real estate portfolios into data-driven, connected hubs.
Our platform is the operating system for buildings — powering IoT, AI, digital twins, and new apps that automate processes, optimize energy use, and create smarter, more sustainable spaces.
