N=5, founded by Ole Christern, Marc Oosterhout, Romke Oortwijn en Peter Hebbin in 1999, is one of the biggest independent agencies in the Netherlands and – as described by N=5 – the most Rotterdam minded agency in Amsterdam. This means a no nonsense mentality. Nevertheless, the agency’s work – predominantly Dutch – is known for its high strategic and creative quality and distinctive style – though in recent years it has become slightly more ‘popular’ in tone and feel. The agency has created well known campaigns for KPN (“Goeiemoggel”), LOI (“Holland becomes smarter and smarter”), and Rabobank (“The bank with ideas”). One of their most awarded concepts in recent years was Interactive Billboard.
