The consultancy was hired to offer creative input to Williams as it sought to rejuvenate its brand in the highly competitive Formula 1 market with the season preparing to get under way again with the first race of the season in Melbourne.
Williams F1 competes with 10 other F1 teams for sponsorship opportunities. The team was looking to refresh its image, improve its appeal and "look, feel and behave like a world class team" that major corporate sponsors would proudly associate with over the long-term.
Scott Garrett, head of marketing at the WilliamsF1 team, said: "The need to stay ahead in this game is paramount, but we feel that we now have a really compelling proposition to enable us to do that. We live and breathe racing, but we do so in the purest way possible: that is something that really resonates our partners."
Last month, Swiss luxury watchmaker Oris renewed its sponsorship of the WilliamsF1 team for the fifth consecutive year.
In other news, Allianz has confirmed the extension of its F1 sponsorship programme. The renewed deal, which originated in 2000, marks the eighth consecutive year that Allianz will be involved in F1 and with WilliamsF1.
At the launch of this season's car, the FW29, last week, WilliamsF1 unveiled a new on-car sponsor in Chinese PC manufacturer Lenovo.
