Mobile marketing solutions provider Sponge has revealed that it has doubled its agency client division in the space of 12 months. Sponge won its 50th agency account in October. The division is made up of above-the-line, digital, integrated and sales promotion agencies which use Sponge for technical services and project management to run mobile marketing elements of advertising campaigns. 
Sponge has worked on a number of high-profile campaigns this year, including Birds Eyes Be Mortgage Free promotion and the multi-award winning Royal Navy Get The Message online and mobile recruitment campaign. 90% of the mobile solutions Sponge works on for brands are part of an integrated campaign.
Sponges rapidly growing agency division is testament to our specialist knowledge and understanding of how agencies work and what their clients need, says Sponge Client Services Director, Douglas McDonald. Our key strengths are a combination of education, technical delivery and a commitment to gold standard account management.
Its as a result of the integrated nature of these campaigns that we only partner with agencies, rather than going direct to the client. After all, if you want a good sales promotion, you are going to want your sales promotion agency to handle that and trust them to deliver on all aspects of the promotion. In turn, our partners know that we deliver to the same high standards.
Advertising agency BBH has worked with Sponge on a number of campaigns. Its Head of Mobile Development, Peter Sells, says:
Our policy at BBH Content is to select the best-of-breed production partners to support the mobile campaigns we create for our clients. I would certainly recommend Sponge as one of those partners.
