Damon Dash (born May 3, 1971), also known as Dame Dash, is an American entrepreneur. Dash is Jay-Z's former manager and business partner at Roc-a-Fella Records, and in 1999, he organized a tour for Jay-Z which made $19 million. However, their relationship soured as a result of two subsequent events. The first was when Roc-A-Fella Records was purchased by Def Jam Recordings (which had previously only owned half of the company) in 2004, after which Jay-Z agreed to take a job as Def Jam's president. Then, in the fall of 2005, Jay-Z bought Dash out of his stake in Rocawear. In April 2014, it was announced that Dash is also involved with Blind Debit, a fingerprint payment application being developed by Dez White.
