KXTbio, Inc. is a privately held biotechnology company based in Chapel Hill, North Carolina. KXTbio was founded in 2011 by Dr. John Sondek, a professor at the University of North Carolina at Chapel Hill and Dr. Mirko Stange, a life science entrepreneur and Managing Partner of the life science consultancy Ventac Partners in Düsseldorf, Germany. In 2012 Dr. Sezgin Ozgur joined the company as a CEO. All three founders orginally met when Sezgin and Mirko started their graduate work at UNC and both considered working for John who was an assistant professor at that time. Today, the company applies some of the patents generated during these times to offer innovative drug discovery platforms and new tools to academic and industrial research to help generation of novel small molecule therapeutics focusing on protein-protein interactions.
