When Apple acquired Beats, R/GA needed to break out a new shop, to avoid conflict of interest. The agency became known as Hustle. Although not very visible to the outside world, the agency is actually an international entity primarily based in Los Angeles and London. London designed the logo, and Los Angeles gave it wings.
In true globetrotter fashion, what better name for an agency than Hustle—considering the nature of the advertising agency/design studio world. Always hustling, never compromising.
