In his new role, Grimmer will be responsible for driving the global expansion of Fetch beyond its three offices in London, San Francisco and Berlin. He will work with, and report to, Fetch’s founder and chief executive, James Connelly.
Before HMDG, Grimmer was the managing director of Publicis Groupe’s digital shop Zed and the commercial director at ZenithOptimedia. Last year, he acted as a strategic consultant for Vevo.
Connelly said: "Since Fetch launched in 2009, we’ve grown 100 per cent year on year, attracting blue-chip clients and exciting businesses for provision of mobile media, strategy, creative and analytics services. As we embark on our next phase of growth, having Greg join the management team is a great sign of intent and ambition and I’m glad we were able to attract him."
