Co-reactive GmbH

Co-reactive GmbH, based in Germany, specializes in innovative carbon mineralization technology, providing sustainable solutions for the construction industry with its carbon-negative product CO-SCM. Founded in 2024, Co-reactive GmbH operates from Erkrath, Germany, focusing on carbon mineralization technology. The company has completed 2 deals, with its latest funding round being a Seed round on January 28, 2026, where it raised EUR 6. 5 million led by High-Tech Gruenderfonds.

This funding will support its expansion into demonstration plants and larger industrial facilities. Co-reactive specializes in carbon mineralization technology, specifically offering a high-performance, carbon-negative Supplementary Cementitious Material (SCM) known as CO-SCM. This innovative product transforms CO2 into stable carbonates through a proprietary process, enhancing the strength and durability of cement-based construction materials. CO-SCM is engineered to maximize pozzolanic reactivity, making it suitable for various cement and concrete applications across multiple industries.

The primary use case for CO-SCM is in low-carbon construction projects, where it acts as a sustainable alternative to traditional SCMs, contributing to the carbon neutrality goals of the construction sector. The company targets geographical markets that prioritize sustainability in construction, including Europe, North America, and select regions in Asia, where regulatory frameworks support the use of eco-friendly materials. Co-reactive generates revenue through direct sales and partnerships within the construction and materials industry. Their business transactions typically involve B2B relationships with construction firms, suppliers, and concrete manufacturers who utilize CO-SCM in their projects.

The pricing structure for CO-SCM is designed to remain competitive with conventional SCMs, enabling clients to incorporate this sustainable material without incurring additional costs. As CO-SCM is positioned as a flagship product, transactions may occur through bulk orders delivered in big bags or silos. The company's focus on sustainability aligns with the growing demand for low-carbon materials in the construction sector, enhancing their market attractiveness and facilitating long-term client relationships. In January 2026, Co-reactive GmbH raised EUR 6.

5 million in Seed funding to expand its CO₂-to-construction-material process from pilot scale to a demonstration plant and to plan larger industrial facilities. The company aims to launch new products in the carbon mineralization segment and expand into markets across Europe, North America, and select regions in Asia by 2027, capitalizing on the increasing regulatory support for sustainable construction materials.
