An undisclosed source told Campaign that the changes were due to "management restructuring" after losing Apple, a major client for Eight.
Chris Fjelddahl, the remaining managing partner at Eight in Hong Kong, clarified that the company is still on an open contract with Apple in China, but revealed that Eight is "currently restructuring the team in Beijing to raise its quality and level of delivery, and is indeed replacing a number of people."
Fjelddahl said Eight is retraining its team in Hong Kong before announcing "a new set-up in Beijing later this year".
Brian-Boys opened a new consultancy, Alchemy Asia in July this year. Several of his new team members were ex-Eight employees, including Andrew Kane.
In the same month, Kyme opened his own start-up agency Kymechow, taking former Eight senior executive Lorraine Liu with him.
Eight Partnership was founded in 1993.
