Career Overview
KSI started his YouTube journey in 2009, uploading FIFA gaming videos and commentary. His energetic personality and comedic timing helped him build one of the UK's largest YouTube channels. As a founding member of the Sidemen in 2013, KSI helped establish the group that would become Britain's most successful YouTube collective.
Beyond YouTube, KSI has successfully transitioned into professional boxing, music, and business. His boxing matches against Joe Weller and Logan Paul (twice) broke YouTube records and helped legitimize influencer boxing as a sport. His music career has produced multiple platinum records, and Prime Hydration, co-founded with Logan Paul, has become one of the fastest-growing beverage brands globally.
Boxing Career
KSI's boxing journey began with a challenge match against fellow YouTuber Joe Weller in 2018, which he won via TKO. This led to two high-profile fights against Logan Paul—a draw in 2018 and a split-decision victory in 2019. These fights generated millions in revenue and millions more in viewership.
After defeating Logan Paul, KSI continued his boxing career with wins over professional fighters, demonstrating his commitment to the sport. His fights regularly sell out arenas and generate massive pay-per-view numbers, proving that influencer boxing has mainstream appeal.
Music Career
As a musician, KSI has released multiple albums and achieved chart success with tracks like "Lamborghini," "Down Like That," and "Holiday." He's collaborated with established artists including Lil Wayne, Rick Ross, and Anne-Marie, bridging the gap between YouTube and mainstream music.
His ability to sell out concert tours and achieve platinum certifications demonstrates that his music career is legitimate, not just a vanity project. KSI has proven that YouTube fame can be a launching pad for success in traditional entertainment industries.
Prime Hydration
In 2022, KSI and Logan Paul co-founded Prime Hydration, a sports drink that became a global phenomenon. Despite being former rivals, their partnership created one of the most successful celebrity beverage launches ever. Prime products frequently sell out in stores, and the brand has secured partnerships with major sports organizations including the UFC and Arsenal FC.
