Amulet Capital Partners-backed Unlock Health, a technology and services growth platform, completed the acquisition of SPM Group, a digital-first, full-service healthcare marketing agency, from Corridor Capital, a private equity firm. Financial terms were not disclosed. “It has been a privilege to collaborate with Patti, Larry, Amanda, Joel and the rest of the SPM Group leadership team to help evolve an already highly competitive business within hospital and health systems into a digital, full-service, healthcare-focused marketing agency. Corridor’s purpose as a firm is to ally with strong management teams of lower middle market business services companies to help them achieve their full potential,” Craig Enenstein, Corridor Capital CEO.
