John Katsaros is a principal at Silicon Valley-based Internet Research Group (IRG), a leading market research and consulting company focused exclusively on helping innovative companies gain market share. In March 2000, the original company named IRG, which Katsaros had founded, was acquired by Jupiter Communications. IRG provided strategic consulting for dozens of high-tech companies, including IBM, Lotus, Cisco, Oracle, Sun, and Hewlett Packard, as well as some of the Valley’s brightest venture-backed start-ups. Subsequent to working with Jupiter, Katsaros, along with Peter Christy, started a successor research company, NetsEdge Research Group which they later renamed Internet Research Group after the original IRG partners obtained the rights to use their former brand name. Katsaros has more than thirty years’ experience in senior-level sales, marketing, product development, and business planning positions in a variety of environments ranging from Fortune 500 companies to start-ups. He is also the author of Selling High Tech (1994), and was a contributing author to Tricks of the Internet Gurus (1993). He is a frequent speaker at conferences and has written many reports on electronic commerce and infrastructure. Industry and national media call Katsaros for commentary about innovation-related events. He has also appeared as an industry expert on CNBC and CNN.
