Naef was previously corporate sales director for two years at MCI UK after starting as a sales executive in 2005.
As part of the business client services team at Grass Roots Group, Naef's role is to identify and target new business. He told C&IT: "Grass Roots is going through a period of transition as our four events businesses are merged together, which will really help our clients to access the depth and breadth of our offering. It is an exciting time to join and I can't wait to get stuck in."
This follows a series of significant appointments and promotions including Des McLaughlin, Grass Roots group managing director of meetings and events and ex-BI Worldwide's Richard Bandell as Grass Roots group chief executive officer.
