I have worked with Chris since 1998 starting out at Abrizio, a pioneering terabit switch fabric company. I have since worked with Chris in a number of other ventures where he was an investor and a board member. He has an excellent grasp of technology, its associated applicability in solving relevant market needs, and more importantly, how to make a great business out of the venture. He spends a great deal of time and energy to work with the team in his portfolio companies helping to solve most any issues. Chris has a great deal of integrity and takes immense interest in working with entrepreneurs to help them be successful. It would be a pleasure to work with him again.
