Director Will Mould and creative director Paul Stanway are leaving Slice, which Mischief CEO Mitchell Kaye has vowed will now begin 'a new era'.
Mould, who is leaving after 14 years at Slice, is expected to depart by the end of the year. Meanwhile, Stanway's resignation follows nine years at Slice, which became a subsidiary of Mischief in July 2011. They would not reveal their plans for the future.
While they will not be direct replacements, Alec Braun and Tom Rutter have been brought in from experiential marketers Jack Morton Worldwide, where they have both worked for eight years.
It is understood the introduction of Braun as strategist and Rutter as production director is part of a broader effort to build up the Slice senior team.
Kaye will now play an interim CEO role at Slice. He said: 'We are gearing up for a new era at Slice, and recruiting Alec and Tom - two guys with such a strong track record - is very exciting.'
