Gabe Leydon leaves MZ to focus on crypto, Kristen Dumont named CEO

Cofounder Gabe Leydon is resigning the top post at mobile game publisher MZ (better known in the past as Machine Zone) to focus on his interest in cryptocurrency and real-time messaging. His No. 2 executive, Kristen Dumont, has been named CEO of MZ.

In addition, Vincenzo Alagna, MZ’s chief technology officer of games, has been appointed president of games. That’s a big change for MZ, which has made mobile games such as Game of War: Fire Age, Mobile Strike, and Final Fantasy XV: A New Empire. Those games have generated $4.5 billion since 2014 on iOS and Android alone, according to measurement firm Sensor Tower.
