Certn, a background screening solutions provider, completed the acquisition of Credence, an eDiscovery services provider. Financial terms were not disclosed. "Improving the way companies carry out background checks has always been one of our stated goals at Credence. When I saw the way Certn perform these checks, it was obvious that with their technical knowledge and the quality of our existing business, the combination would create a significant presence in the background screening market to the benefit of our existing and future clients," Hedley Clark, Credence Owner and Managing Director.
