Despite the high traffic, Deezer almost immediately ran into financial problems—during the first half of 2008, the company saw revenue of just 875,000 euros, not enough to pay its licensing fees.[7] In July 2008, the company began running ads itself through advertising agency Deezer Media; in October, Deezer secured $8.4 million in funding from AGF Private Equity and CM-CIC Capital Prive, bringing total investment in the company to $15.8 million.[9] The company introduced mandatory registration in February 2009 to gather more precise data on users, in order to run more targeted ads, and in November 2009 began running audio ads between songs.[7]
