One of Pittsburgh’s fastest growing companies, GrayMatter targets tripling revenue and employees over the next few years. “The market has caught up to what we do and now is the time to capitalize on it,” said GrayMatter CEO, Jim Gillespie. “Hamilton Robinson’s investment last November has allowed GrayMatter to rapidly expand its efforts to digitally transform industrial operations and empower people in the manufacturing, water and energy markets. Our teams both work tirelessly to solve operational problems for our customers. Not only is investing in TMMI a good market fit, it’s a fantastic cultural fit,” said Gillespie.
