Sollecito (pictured) was most recently senior vice-president, client solutions, at cross platform measurement firm Symphony Advanced Media. 

Prior to that, he was senior vice-president, insights and media strategy, at Al Jazeera America. 

“Brand and network marketers alike are trying to solve the cross-platform measurement puzzle – where and when exposures happen, and which ones make a true impact,” said Don Simons, head of industries for GfK in North America.

“John brings a wealth of experience and innovative thinking to understanding media use today, in a world of fragmented attention spans and seemingly unlimited touchpoints. He will help our clients make sense – and decisions – from all of the data at their disposal, with an up-to-the-minute perspective on the roles media is playing in consumers’ lives.”
