Wellspring Capital-backed Airswift, a workforce solutions provider to the energy, process and infrastructure industries, completed its merger with Competentia, a staffing solutions provider. Financial terms were not disclosed. "It just made sense for two private equity-backed companies to get greater scale, greater investment dollars for growth and greater reach into other business segments. We’re situated in a very strong position for growth anywhere around the world," Janette Marx, Airswift CEO.
