Co-founder and CEO, Warren Katz, to Retire

Cambridge, Mass., January 12, 2012– VT MAK (MAK), a company of VT Systems, Inc. (VT Systems), today announced the retirement of CEO and co-founder, Warren Katz, effective January 20. Katz founded MAK in 1990 with John Morrison and has acted as COO and CEO during his twenty-one years with the company. Katz and the MAK board of directors have selected Daniel J. Schimmel as the company’s new CEO. A smooth transition is expected, with no disruptions to operations as Schimmel and Katz have been working together to execute a transition plan over the past few months. Notwithstanding his retirement as a CEO, Katz will remain a consultant and advisor to the company.

Katz spent his career dedicated to the transformation of the Modeling and Simulation industry with a dedication to open standards and the COTS product marketplace. He contributed to the original Distributed Interactive Simulation (DIS) standard and pushed for the adoption of the High Level Architecture (HLA). MAK, under Katz’s direction, invented the open standards distributed simulation infrastructure marketplace. 

Schimmel has over twenty years of experience leading cutting-edge software and information services companies that have delivered high growth and profitable returns for investors. Most recently, Schimmel managed the growth of Pyramid Research, a seller of syndicated analyst content covering the global communications and media industries. Prior to Pyramid, Schimmel was CEO of OneSource Information Services, the market leader in delivering web-based company and industry information, which led to a successful IPO.

Schimmel earned a BA degree in economics from Harvard University and an MBA from Harvard Business School. He has served on the boards of venture-backed companies and was recognized as an Ernst & Young Entrepreneur of the Year in 2001.

“The sustainability of a successful and reputable company is directly related to the strength, courage, and foresight of its leader. Warren Katz has exemplified these standards thoroughly and built them into MAK's foundation. With Dan Schimmel's proven expertise and skill, he is the ideal candidate to lead the company and ensure that its goals and aspirations will continue to steer it in a positive direction.”
