MDP’s track record of successful partnerships with vertical enterprise software, procurement and supply chain, and government services and technology companies will greatly benefit Unison as we enter this pivotal new chapter in Unison’s history.”

“We are excited to enter into this partnership with the talented team at Unison and Carlyle. Unison is an innovative company with a longstanding track record of success and an established strong leadership position in the government procurement software market,” said Matt Norton, Managing Director and Head of the Business & Government Software and Services team at MDP. “Unison sits right at the intersection of our team’s core focus areas, and we look forward to applying our extensive expertise to help drive Unison forward in the service of the U.S. federal government and its key contractors.”

Steve Bailey, Managing Director at Carlyle, said: “We have had the pleasure of working with Reid and the Unison team to help them grow into the market leader they are today. The team has executed their plan and grown through investment in products, continued organic growth and the completion of two strategic acquisitions to expand their solutions and accelerate international growth. Our partnership with Unison is aligned with Carlyle’s long history of investing in leading industry-specific application software companies. We’re excited about the opportunity to partner with MDP during the next phase of Unison’s growth.”

The transaction is anticipated to close in the third quarter of 2022.
