Adjust acquires smartphone measurement tool from Japan’s CyberZ

Mobile measurement firm Adjust has acquired Force Operation X (F.O.X), an advertising effectiveness measurement tool for smartphone apps, from Japanese marketing agency CyberZ.

The move is Adjust‘s fourth acquisition in a year, and it represents its expansion in Asia and the Japanese mobile economy. I’m heading to Adjust’s Mobile Spree conference in San Francisco today to moderate a panel on user acquisition for games.
