About Arkeon

Arkeon is an Austrian biotech founded in 2021 by Gregor Tegl (CEO), Simon Rittmann (CSO), Günther Bochmann (CTO) and Michael Mitsakos, building on more than a decade of archaea research including at the University of Vienna. Its patented one-step gas fermentation process uses archaea, ancient single-celled microorganisms, to convert captured industrial CO2 and hydrogen into amino acids and functional peptides, without agricultural feedstock. Initially targeting protein ingredients for food and beverages, the company later pivoted to producing single amino acids such as leucine from CO2 and ran a 150-litre pilot plant. Arkeon raised more than EUR 10 million, with investors including ICL. In 2025 the company filed for insolvency.
