While media outlets reported in 2014 that he is a first cousin of Nicole Scherzinger, an American singer formerly of the girl group the Pussycat Dolls, Dok2 said in a 2015 interview, "The report about me being first cousins with Nicole Scherzinger is wrong. We share the same blood, but the relationship is complicated. I haven't even met her."
Dok2 signed to Future Flow Entertainment when he was 13 years old. By the time he was out of his teenage years, he had written and produced songs for established Korean hip hop groups, including Drunken Tiger, Dynamic Duo and Epik High.
In 2011, Dok2 and rapper The Quiett formed Illionaire Records. Despite its small size, Illionaire Records is considered one of the most influential hip hop record labels in South Korea due to the popularity of its artists.
In 2014, Dok2 was a judge on the third season of the TV rap competition Show Me the Money, where he and The Quiett were the producers behind winning contestant Bobby of the band iKon. They again participated in the show's fifth season and were the producers behind the second running up, Super Bee. Dok2 again participated in Season 6 as part of a producer team with Jay Park (AOMG and H1GHR Music)
