Agency account change Market: Grabarz & Partner Loses Porsche Account; Serviceplan Succeeds
Hamburg-based Omnicom subsidiary Grabarz & Partner publicly bade an emotional farewell to long-time client Porsche after losing the account. Ralf Heuel, the agency’s CCO, reflected on the end of a ten-year relationship, described the impact on his team and argued agencies should be candid about losses as well as wins. Heuel issued a brief public message of goodwill — "KEEP ON PUSHING, PORSCHE AND SERVICEPLAN. SERIOUSLY." Porsche informed Grabarz & Partner that Serviceplan will become its new global lead agency effective January 1, 2027. The farewell post, widely praised across the industry, raised questions about how Grabarz & Partner will move forward; the story was reported by Mehrdad Amirkhizi on Horizont on August 12, 2026.
Agency account losses and successor appointments are relevant to the agency sector and client-agency market dynamics but do not constitute major industry-wide infrastructure, policy, or platform changes.
