by Herman Manson (@marklives) For most people, Marcello Serpa (@Marcello_Serpa) is the guy who made Havaianas famous. It was his first account at his own agency and he has helped grow a local brand in Brazil into a global powerhouse. For ad people, he is that, of course, but more importantly to them, I suspect, is that he and a business partner launched his own agency (AlmapBBDO), made it, and made it fly.
