Daniel Bergmann, the founder and president of Stink, said he sought a global chief executive to "unify Stink’s overall group strategy", adding that the goal was "to be a full-service creative company".
Morris joined Stink on 3 May with a remit to oversee the company’s operations across Europe, Asia and the Americas.
He had worked at MediaCom Beyond Advertising, MediaCom’s content division, since 2011, becoming its global head in 2013.
Morris said: "I’ll be working with our global offices… to ensure we have the best talent in that market and our full services across Stink, Stinkdigital and Stinkstudios in every market we operate in.
"As we move into an increasingly global world, and brands, agencies and publishers require high-quality production in many markets across the world, we believe it is also important to understand local culture and context. We will also invest in new countries to be announced in the future."
This is not Morris’ first job at a production company. He was previously the director of digital strategy and content at Twofour Group, which was acquired by ITV in 2015.
