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

HEUKING advised Düsseldorf-based DeepTech start-up Co-reactive GmbH, developer of technology for converting CO₂ into cementitious additives, on the legal aspects of its successful seed financing round, which raised EUR 6.5 million. Existing convertible loans (CLAs) were also converted as part of the round.

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.

The HEUKING team led by Dr. Patrick Müller, LL.M. (Partner), and Laura Jochem, LL.M. (Associate). HEUKING regularly advised start-ups and VC investors in various VC financing rounds.
