ECI Software Solutions appointed Ron Books CEO. Books previously served as ECI’s CEO from 2009 to 2021 and returns to lead the company as Trevor Gruenewald retires from the role. “ECI has been an important part of my life for nearly three decades, and I couldn’t be more excited to return as CEO,” Books said. “Trevor has done an exceptional job leading ECI through a period of tremendous growth and transformation, and I’m grateful for the foundation he and the team have built. I know this company, its customers and its people deeply, and my focus will be on building on that momentum as we continue investing in the technology that helps our customers run better businesses.”
