NEW YORK MDC Partners' Crispin Porter + Bogusky has split with Method Products; both parties claimed the dissolution of the relationship was amicable, though they declined to give reasons for the breakup.
Miami-based CP+B had worked with the client for the past three years.
In a statement, the agency said, "We are extremely proud of what we were able to accomplish together during our partnership. Recently, however, we have both agreed that the time has come to part ways."
The shop will continue to be a shareholder in Method.
It is unclear if the client intends to hold a review. Measured media spending in recent years, mainly to support print efforts, has been $1 million or less, though some design, promotions and interactive initiatives have also been in the mix.
In fact, CP+B's best-known work for the San Francisco-based cleaning products provider was comeclean.com, a Web site allowing consumers to share confessions for subsequent "cleansing" by Method's environmentally friendly fare. That work garnered a cyber Grand Prix at the Cannes Festival in 2005.
Despite the Cannes recognition, Method had been one of CP+B's smallest and least visible clients. The agency fashions high-profile campaigns for Burger King and Volkswagen, among others.
