Dive Brief: 

• 360i CEO Bryan Wiener will be leaving his post to serve as chairman of social media management and analytics firm Expion. 
• Expion is the preferred social platform partner to the 360i agency, and parent company Dentsu has been invested since 2012. 
• Wiener will stay on as chairman to 360i, but will turn over operational duties while he chairs Expion. 

Dive Insight: 

With the preferred partnership between 360i and Expion, it seems like a natural progression for Wiener to serve as chairman for both organizations. He can help both companies collaborate and communicate more effectively to help reach common goals.
