BuildingMinds was founded in 2019 by Schindler Group, the Swiss multinational manufacturer of escalators, moving walkways and elevators, to meet the company's need for building data monitoring and management.

With EUR 150 million in funding from Schindler and technological support from Microsoft, we have since expanded to become a major international provider of software as a service (SaaS) for real estate managers, meeting their needs in the areas of reporting and ESG, portfolio management and digital building twins. Our portfolio of services is continuously growing.

We help create a digital brain that drives the performance of real estate portfolios, boosting efficiency, sustainability and long-term value.
