Kirill Despodov was born on November 11, 1996 in Kresna, Bulgaria, just two hours away from the city of Thessaloniki.  Despodov  started out in the Litex Lovets academies and made impressive progress in the junior age categories, player as a winger.

The Bulgarian foward made his first team debut at the age of 15 on May 12, 2012. He stayed at Litex Lovets until 2016, playing in 49 games, scoring six times and providing one assist.
