Cleantech startup Again has raised $43 million in series A funding round, with proceeds aimed at supporting its growth and build full scale decarbonization plants.

Founded in 2021, and spun out of the Danish Technical University, Copenhagen-based Again provides solutions to decarbonize heavy industry by using fermentation to turn CO2 into valuable products. The company’s technology combines CO2 captured from flue gases, and hydrogen with a biological feedstock to produce green base chemicals through a patented fermentation process. According to HV Capital, one of the lead investors, Again’s plant in Denmark already converts up to a ton of CO2 per day into essential chemicals like acetate, vital for industries such as adhesives, plastics, and cosmetics.

The new capital will be used to build additional facilities and support the company’s expansion in Europe and the U.S. as well expand its product portfolio.

Maximilian Kufner, Again Co-Founder, said in a LinkedIn post:

“Grateful to our new and existing investors for supporting us on this journey as well as the many partners we collaborate with daily. None of this would have been possible without the amazing work of the entire Again team, who are pushing the boundaries of biotechnology to solve the climate crisis. We are also grateful to the many partners we work with who have made this milestone possible, including HELM AG, DTU – Technical University of Denmark and SINTEF.”

The round was co-led by HV Capital and GV (Google Ventures), with participation from KOMPAS VC, EIFO and CSC Leasing, and existing investors ACME Capital and Atlantic Labs.
