Foundation, Milestones & Roadmap.

Founded in 2009 by Prof. Dr. Uwe Landau, the first systems were developed in close collaboration with our scientific partners at the Free University Berlin and Beuth University of Applied Sciences. After several years of research and microbiological studies, the first commercial licensee, Feindrahtwerke Adolf Edelhoff, ramped up manufacturing and sales of AGXX® coated metal meshes for consumer and industrial water applications in 2014. Since 2018, Ayad Abul-Ella joined Largentec as interim CEO and drives since April 2022 as group CEO the commercialization of AGXX®into a variety of markets and applications.
