Pentagram is the world's largest independently owned design consultancy. For five decades, it has embraced the philosophy of design as a collaborative discipline, with a structure unique among design firms.The company is run by 25 partners, all practicing designers who are leaders in their individual fields. Working from offices in New York, London, Austin and Berlin, each partner manages his or her own team and projects. This approach enables them to retain the creative intensity that characterises the smallest - and best - design firms. They are the only major design studio where the owners of the business are the creators of the work and serve as the primary contact for every client.
