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. As a teenager he swept the floors of a local barbershop and sold newspapers in order to buy sneakers and shirts.
He developed his work ethic from the example of his mother, who died of an asthma attack when Dash was 15. Dash was sent to a private school in order to receive a better education.
His success helped him discover the different fields he wanted to branch out into.
Married Rachel Roy, January 15, 2005 (separated 2009). 3 children.
