"Matt is a rare breed, being a fantastic manager of people and one of the best strategic practitioners in the game," said Adam Ferrier, founding partner of Naked Communications.
"Matt's a true lateral thinker and Naked has the business model to support his freethinking approach," he added.
In his new role, Houltham will work with key clients include Kraft, 7-Eleven, TAC and AB Foods.
