Born Tyrone William Griffin Jr. on April 13, 1982 and known professionally as Ty Dolla Sign (stylized as Ty Dolla $ign or Ty$).
In the early 1990s, he moved from his native Los Angeles to New York City, living in Brooklyn and developed a friendship with 50 Cent. He then fell in with a manager, Venus Brown, who signed him as part of a duo dubbed Ty & Kory.
Eventually he gained major recognition in 2010 for his feature on YG's Toot It and Boot It, which he had written and produced for Def Jam Recordings. In the summer of 2013, he signed a record deal with Wiz Khalifa's Taylor Gang Records. In November 2015, he released his debut studio album, Free TC, which peaked at number 14 on the US Billboard 200.

Ty Dolla Sign is perhaps best known for his singles Paranoid, Or Nah, and Blasé, as well as his writing contributions to Loyal, Post to Be, and FourFiveSeconds, among others. Aside from his solo music career, Ty Dolla Sign is also a member of production team D.R.U.G.S., alongside Chordz 3D, Buddah Shampoo, Nate 3D, James Koo, Fuego, and DJ Dahi.
