HEUKING advises Düsseldorf DeepTech start-up Co-reactive on its seed financing round

The Düsseldorf-based DeepTech start-up Co-reactive, developer of technology for converting CO₂ into cementitious additives, was advised by HEUKING on the legal aspects of its successful seed financing round. A total of EUR 6.5 million was raised during the financing round and existing convertible loans (CLAs) were converted.

The lead investor in this round is High-Tech Gründerfonds (HTGF). Other investors include NRW.BANK, AFI Ventures, the early-stage impact arm of Ventech (France), and Evercurious VC (Greece). In addition, the company receives subsidies from the Federal Ministry for Economic Affairs and Energy (BMWE).

Co-reactive GmbH is developing a novel carbon mineralization technology that converts CO₂ into high-performance CO₂-negative cementitious additives (SCMs). The aim is to improve the strength and durability of cement-based building materials and thus contribute to the decarbonization of the large-volume construction sector. The company is now scaling up from the prototype to a 1,000-ton demonstration plant. Industrial pilot plants on a ten-thousand-ton scale are already being prepared.

The company was founded in 2024 based on the long-standing research of co-founder Dr. Andreas Bremen at RWTH Aachen University and supported by the EXIST program of the BMWE. Together with Orlando Kleineberg and Willi Peter, the founding team is pursuing its vision of sustainably transforming the construction industry through low-carbon materials.

Co-reactive was legally advised by a team led by Düsseldorf-based HEUKING Partner Dr. Patrick Müller, LL.M. (VC). HEUKING regularly advises start-ups and VC investors in various VC financing rounds.
