Ratings Firm Quantcast Expands in Europe

San Francisco-based online ratings firm Quantcast has acquired Stockholm-based digital ad agency Ad Performance - for an undisclosed sum - and has opened a new office in Milan, Italy.

Ad Performance was founded in 2010 by four former Microsoft employees and offers media buying and ad targeting services. The entire Ad Performance team will now join Quantcast, with co-founder and CEO Anders Uhlin becoming the US firm's Nordics Managing Director.

At its new office in Milan, Quantcast has appointed Ilaria Zampori as General Manager. She joins with more than fifteen years' experience in online display advertising, having previously held senior roles at GroupM's QUISMA, and Hi-Media in Italy.

Phil Macauley (pictured), European MD at Quantcast, says the Ad Performance buy and the expansion into Italy bring the firm's technology and proprietary data to advertisers, agencies and publishers in these markets for the first time.
