Haver was born in Brussels and raised in the city's Laeken district, to a Rwandan father and a Belgian mother. Haver and his siblings were raised by their mother, as his father, a successful architect, was killed during the 1994 Rwandan Genocide, while visiting his family. Haver attended a Roman Catholic Jesuit school after he failed in the public school system at the age of sixteen. He formed a small rap group with friends while still in school. His early influences included Belgian singer-songwriter Jacques Brel, Cuban son, and Congolese rumba. Even though he was raised as a Belgian, he has stated that he did not always feel that he was from Belgium.
