Again

Again is a Copenhagen-based carbon-utilization biotech spun out of research from the Danish Technical University, Stanford, and MIT. Rather than storing captured carbon, Again feeds industrial CO2 waste and hydrogen into bioreactors where AI-designed biocatalysts ferment the gas — much like brewing — into commercial-grade acetate and other green chemicals used in adhesives, solvents, plastics, textiles, cosmetics, aromas and flavors, industrial enzymes, proteins, and fertilizers. The company runs carbon-utilization facilities in Copenhagen (CPH-1), Texas City (TXS-1, with Dow and HELM AG), and Porsgrunn, Norway (NOR-1). Again raised a $43M Series A co-led by GV (Google Ventures) and HV Capital in 2024. No public developer API surface was found during API Evangelist enrichment.

Again is profiled on the APIs.io network. Tagged areas include Company, Frontier Tech, Biotechnology, Carbon Utilization, and Climate Tech.
