Heralded as Twitter meets iTunes and Spotify, the platform allows users to create a profile and share music through recommendations with other people. User accounts are credited with 20 per cent of the track value when their recommendations are purchased by someone in their network.
The agencies will be responsible for delivering traditional media relations alongside establishing and implementing a social media strategy to launch and promote the site.
A Beta site has been launched and music and technology influencers invited to trial the platform before its official launch next month.
Chris Reed, managing partner, Brew said: 'We're really excited to be working with mflow. It takes the best aspects of Twitter, adding music discovery and a legal music sharing capability, to develop a new application which the current Beta testers are really getting into.'
Atan Burrows, marketing director, mflow said: 'Seeding this service with the influencers is vital to our success before we launch with a larger-scale campaign in mid-April.'
Brew and Seventy Seven PR are the respective digital and consumer divisions operating within the Fishburn Hedges Group.
