Speed Communications has seen the separate departures of two of its managing directors.

Steve Earl and Stephen Waddington, who have led the agency since it was founded in 2009, have joined Zeno and Ketchum Pleon respectively.

Earl will be MD of Zeno Europe, heading up the agency's European expansion. He will be responsble for charting the firm’s growth in London and other key European cities. Also joining Zeno is John Kerr, formerly Asia-Pacific head of digital for Edelman.
