UK startup Mixcloud has been building a healthy audience for its streaming DJ mixes, but there is competition out there. US startup Dubset has announced a $500,000 financing round for its own service, which serves up mixes while paying royalties to the rightsholders for individual tracks. The company plans to build more DJ facing tools according to Business Insider, while also launching more mobile apps. Dubset launched in February this year (Bulletin, 21-Feb-11), although it was founded in 2009. 200 DJs are providing mixes for the service, which has also just added UMG exec Steve Rifkind to its advisory board.
