Kountin Fast Cash was founded by Yun Jay & producer Supa Mario who are former members of a group known as Atlanta Prospects. After ATL Prospects split up due to commitment issues with other members, Yun Jay and Supa Mario who met in Lithonia High School through a mutual friend, met a young hungry rapper D.C. The Domecrusher. Impressed by his machine gun flow, they asked him to get down with the team and along with Mario’s younger brother Zay the group Kountin Fast Cash was formed.
