Berlin-based Alcemy is a technology-driven company focused on reducing the carbon footprint of the cement and concrete industries—sectors contributing approximately 8% of global CO2 emissions. Founded in 2018 by Leopold Spenner and Dr. Robert Meyer, Alcemy addresses the urgent need for sustainable alternatives in an industry vital to global construction.

The company develops predictive software tools that optimize the production of cement and concrete by enhancing quality control while significantly lowering CO2 output. Their innovations allow for the use of low-clinker and low-carbon mixtures, which have achieved real-world implementation beyond laboratory tests. Alcemy's solutions have been adopted by a third of Germany's cement plants and over 30 ready-mix concrete facilities, marking a significant step toward decarbonization.

Alcemy is supported by substantial investments, including recent funding rounds of €9.2 million and €10 million led by climate-focused venture firms such as Galvanize Climate Solutions and Norrsken VC. These funds are fueling the expansion of its AI-driven platform to international markets, including the United States.

One notable project involves a partnership with Spenner, Germany’s fifth-largest cement producer, to create low-carbon cement mixtures for commercial use. The company's ambitious goal is to prevent 100 million tons of CO2 emissions annually by 2030 through its innovative technologies and collaborations.

Alcemy exemplifies how cutting-edge technology and sustainability can align to transform high-emission industries for a lower-carbon future.
