“The Jonas family of companies was a great permanent home for our family business. It was clear from the beginning that Jonas shares our belief of taking great care of our employees and customers. They stand behind their ‘Software for Life’ promise.”

John Brookbank
Shareholder & CEO, BEC Legal

“I joined Jonas through the acquisition of XN Leisure in 2010. Not only has the business thrived under Jonas ownership, it has also been a fantastic place for me to grow my career.”

Darrell Boxall
Managing Director, XN Leisure (now Portfolio Manager, Jonas UK)

“One of Jonas’ key success factors is autonomy and decentralization. Since selling my software company to Jonas in 2012, I’ve continued to run my business independently while being able to tap into the knowledge and best practices from other Jonas companies.”

Eric Rennagel
Founder & CEO, My Media Box

“We had the autonomy to keep our beautiful staff and maintain our culture. But we also got to become part of a bigger Jonas family that would support us and help us grow even more. This is why we believed Jonas was a great fit for us at Shortcuts.”

You spend all this time building your baby and you really care about the future of your business and what is going to happen to it. We knew Jonas cared as much about the long term future of EZFacility as we did.
