 Evolving Systems, Inc. EVOL, a leader in real-time digital engagement solutions and services, celebrates its 35th birthday this month. The company was founded in 1985 during a period of dramatic change for a telecommunications industry which was, at the time, experiencing widespread deregulation and, simultaneously, the birth of mobile. Over the last three and a half decades, Evolving Systems has built a unique, in-depth understanding of how telecom businesses operate.
