MRM Hong Kong is looking for a permanent managing director and aims to confirm a replacement in June.
Cripps said the challenges in the digital industry at the moment include the absence of enough skilled digital talent across the whole range of skills and a reluctance among clients in the region to embrace digital as a strategic or lead medium.
Jason Chau remains in his role as the managing director of MRM Greater China.
MasterCard, Intel, Microsoft Advertising, Dell, adidas and General Motors are among MRM Worldwide's key clients. The Hong Kong office also hosts a digital and analytics department.
