‘Big Jack’ Jack Mulowayi

Residing in Hemiksem, Belgium, this heavyweight made his professional boxing debut in the fall of 2015. Since then he entered the ring 18 times, emerging victorious on 13 occasions. An impressive record, which includes the African and Asian title. Standing 6’ 4’’ (193 cm) tall and weighing 242 pounds (110 kg), Big Jack is known for his destructive knock-out power.



Born in Kinshasa, Congo in 1987, Jack Mulowayi found his way to Belgium at a young age. From the early beginnings, it became quite clear Jack had a knack for sports. He started playing soccer at local club Germinal Beerschot, where he teamed up with the likes of Mousa Dembélé and Radja Nainggolan. However, his big frame drove him towards basketball and he ended up playing with the youth divisions of first division club Antwerp Giants for several years.

His future looked bright, until he was involved in a car accident that left him unable to compete at the highest level of basketball. During his rehabilitation, he started boxing. It wouldn’t take long for people to notice his raw talent. After plowing his way through the amateur ranks, he turned pro in 2015. Clocking in at an impressive 242 pounds (or 110 kg), he would soon be known as ‘Big Jack’.

His first major success followed in 2020, when he beat Morris Okolla in a bout – held in his birth place Kinshasa – for the African title. Only four months after that, he added the Asian title to his pedigree. Impressive victories, but funnily enough he really gained notoriety through a loss. In 2022, he faced Olympic champion Bakhodir Jalolov and managed to stay in the fight until the eighth round. A spectacular achievement, that truly cemented his place amongst the best heavyweights in the world.

A reputation that earned him a shot at the EBU-title, in which he fights Granit Shala on the 25th of February 2023. Winning would mean he enters a distinct group of elite fighters that contend for a shot at the world title, currently held by British phenomenon Tyson Fury (34).

The main challenge however, is to find the funds to make his dreams come true. Because in spite of being at the very top of his sport, finding sponsors to ensure he can solely focus on his sport remains a difficult task.
