Clearlake Capital Group has invested in OnShift, the companies announced last week, with participation from the Ziegler Link•Age Fund II and existing investor Health Velocity Capital. Financial terms of the transaction were not disclosed.

The investment will be used to expand OnShift’s product development in recruitment, workforce and talent, as well as accelerate sales and marketing plans. Dan Groen and Paul Huber of Clearlake will join the OnShift board.

“We are thrilled to add OnShift to our portfolio of growing, market-leading healthcare software businesses,” the pair said in a statement. “We believe OnShift’s strong customer value proposition solving compliance requirements, staff turnover issues and excessive overtime, alongside the company’s culture of product innovation, uniquely positions OnShift to be the LTPAC’s preferred HCM platform.”

Previous financial support came from Draper Triangle Ventures, Early Stage Partners, Fifth Third Capital, Glengary LLC, HLM Venture Partners, JumpStart Inc., North Coast Venture Fund and West Capital Advisors. KeyBanc Capital Markets served as the financial advisor to OnShift on this round.
