The pro-bono work will include social media, experiential activity and content creation, with a focus on music partnerships, and will be led by Cake CEO Mike Mathieson.
Previously, War Child has worked with music acts such as Oasis, Radiohead and Sir Paul McCartney, and most recently Coldplay and The Killers.
War Child’s director of fundraising Ben Knowles said: ‘Choosing Cake to work with us in 2013 was a no-brainer. Mike and the agency’s roots are firmly within the music industry and they understand exactly how to maximise high-profile partnerships such as ours.
‘The team’s experience in creating large-scale music campaigns over the past 14 years for the likes of Coca-Cola, Motorola and Reebok means it is perfectly placed to help us drive awareness of our cause next year.’
