72andSunny, Starbucks’ global ad agency, is not affected by the review. The brand wants to use a specialist shop to handle creative across its European markets in particular.
Starbucks has sent a request for information to several agencies in the UK ahead of a review overseen by Creativebrief.
The coffee chain also works with Oliver, which provides an in-house unit that manages in-store and point-of-sale activity.
Howard Schultz stepped down as Starbucks’ chief executive in April and was replaced by chief operating officer Kevin Johnson.
A Starbucks spokeswoman confirmed the review and added: "With 41 countries in EMEA, we want to celebrate how Starbucks’ coffee leadership comes to life across a diverse region."
