Settman started acting in Skärholmen at the age of ten and studied acting at Södra Latin along with Fredde Granberg and Gila Bergqvist. At age 21 he acted in skits in the youth television show Kosmopol on local television in Växjö. In 1989 Settman started his production company Baluba, which he still owns and runs today. "Ronny och Ragge" (Ronny and Ragge) were perhaps Settman's best-known characters. Settman played Ronny to Granberg's Ragge; the duo was depicted as typical raggare. The characters were introduced in a parody of a popular soap opera, Storstad, and became an instant hit. Settman and Granberg featured on their own show called Byhåla, which was broadcast on Sveriges Television from 1991 to 1993. Upon the suggestion of Swedish musician Christer Sandelin, Ronny and Ragge released their own album with lyrics set to Sandelin's music, which sold 138,000 copies.
