Longtime ECI leader returns as CEO Trevor Gruenewald to remain board member after 18 years with company. Gruenewald transition follows 18 years with ECI including nearly six years as CEO during his tenure ECI grew from domestic software provider into global company serving 25,000 customers across more than 90 countries.
"Leading ECI has been one of the greatest privileges of my career, and I am incredibly proud of what this team has built together," said Gruenewald. "ECI is in a position of tremendous strength, with the right strategy, people, and technology designed to help small and mid-sized businesses compete and grow. As I considered what was right for both my family and ECI's next chapter, it felt like the right time to make this transition. I'm thrilled that Ron has agreed to return, and I look forward to working alongside him as a member of the Board."
"It has been a privilege to partner with Trevor, who built ECI into a global leader in mission-critical software for small and mid-sized businesses. We thank him for his leadership and are pleased he will continue to guide ECI as a board member," said Usama Cortas, ECI Board member and Partner at Leonard Green & Partners, L.P.
