Celsios was founded with a clear mission: To make the decarbonization of the real estate sector simpler, more transparent and economically viable. The platform helps property owners, asset managers and service providers to efficiently manage the entire decarbonization process - from analysis to action planning and implementation.

Celsios removes barriers by facilitating access to reliable data, suitable service partners and customized financing solutions. The platform connects all relevant players to support the real estate industry in achieving its climate targets - without lengthy, costly processes and uncertainties.

The aim of Celsios is to establish decarbonization not only as a regulatory obligation, but also as an economic opportunity and to drive forward a sustainable transformation of the industry.

Celsios was founded in 2024 by Justus Wiedemann, who previously built Quantrefy, an ESG SaaS platform for the real estate industry. Prior to founding Celsios, Justus worked as Head of ESG and gained valuable industry experience that is now being incorporated into Celsios.
