Maxi Itzkoff and Mariano Serkin's already-big roles as exec creative directors at Buenos Aires' Del Campo Saatchi & Saatchi are growing as Del Campo opens in Spain this month, rolling up Saatchi's existing Madrid shop. The pair is behind ever-crazier stunts for Anheuser-Busch InBev's local beer Andes, and the unusual idea of using sweaty dads lounging around the house in their underwear to sell BGH air conditioners, an awards-show crowd pleaser. Says CEO Pablo Del Campo: "Maxi and Mariano follow the best projects and they smell the creative opportunity."
