BetaBoston is reporting a shake-up at LogMeIn’s Xively Internet of Things division. “Several top execs focused on launching new services to support the “Internet of Things” — sometimes called machine-to-machine communication, or M2M — have left Boston-based LogMeIn in recent months. Among those who have left the Xively division in 2014 are chief technology officer Philip DesAutels; Chad Jones, a vice president of strategy; and Les Yetton, the one-time general manager of the group.”
