Blue Rubicon will also be responsible for developing and implementing corporate and consumer campaigns and co-ordinating a network of agencies worldwide, with a view to positioning the service as the new way to listen to music.
The agency will report to Julie Harari-West, international PR director, who was appointed in the summer having worked previously at Weber Shandwick and at the international record industry trade association IFPI.
News of the appointment comes in the week the company announced new investment totaling £81m as it battles with better-known Spotify for market share.
Included in the investment plans are opening offices in both new and existing markets around the world and growing its editorial team.
Deezer offers around 20 million tracks and has seven million active monthly users who have produced 100 million playlists.
Harari-West commented, ‘As we look to use our new funding to accelerate our roll-out across the world, our global marketing and communications effort will be absolutely key to driving take-up and building our brand awareness in new markets.’
