After helping to guide rap star B.o.B.'s career, Jonsin is focusing more on discovering new talent--like Spanish YouTube sensation Leroy. "This kid is a superstar. So we found him and I signed him, and I flew him and his family here," Jonsin said. "The Internet allowed that to happen."

He expanded his Rebel Rock Productions, also signing famed production duo Finatik and Zac along with Danny Morris to his company. He even launched his own motorsports team, Rebel Rock Racing.
