sequestra FlexCo

Founded in 2024 and based in Vienna, Austria, sequestra FlexCo operates as a climate technology company that develops and produces artificial intelligence-based carbonating technologies for mineral materials using industrial waste. In March 2026, sequestra FlexCo raised EUR 3 million in seed funding led by returning investor VSE Beteiligungs, with participation from new investor Dr. Rudolf Fries Familien-Privatstiftung. The round was part of a larger EUR 5 million seed and grant funding.

The firm as of February 2025, is led by its Managing Directors, Lukas Höber and Roberto Lerche. Sequestra specializes in advanced CO2 sequestration technologies aimed at chemically storing carbon dioxide in various industrial waste materials, such as steel slags, red mud, and cement wastes. These products are designed to prevent CO2 from adversely impacting the global atmosphere while simultaneously transforming industrial waste into economically beneficial resources. The technologies developed by Sequestra facilitate the highest possible sequestration outcomes tailored to specific materials, thereby addressing critical environmental challenges.

The company's solutions cater to a diverse clientele, including industries engaged in steel production, cement manufacturing, and waste management, with a focus on markets in Europe, North America, and parts of Asia where industrial waste and carbon emissions are significant concerns. Sequestra generates revenue through partnerships and collaborations with industrial clients seeking to implement CO2 sequestration solutions.   The company will use the March 2026 funding to support product development and expansion plans initiatives.
