Ben Phillips, global head of mobile at MediaCom, named number one in The Drum's Mobile Top 50

Phillips has spent over a decade in the mobile space, joining MediaCom as global head of mobile in 2013 to provide leadership for the agency’s specialist mobile divisions across the UK, Germany, Scandinavia, Singapore and India.

"From outbound SMS campaigns in the early days of mobile through to planning and executing global strategies for the worlds leading brands, I have been privileged to be part of the growth of mobile and to have helped shape the market as we see it today," said Phillips.

"The last 12 months have seen monumental shifts in the inclusion of mobile in digital media campaigns – mobile ad tech is superseding that of desktop as we strive to follow the consumer trends."

Phillips is joined in the top five by Jonathan Milne, chief revenue officer at Celtra; the IAB's marketing director Alex Kozloff; Milton Elias, head of mobile and tech futures at OMD; and Facebook's director of agency partnerships Claire Valoti. The full list can be viewed here.
