Both Logan Paul and KSI rose to prominence on YouTube. Paul had a rapidly expanding vlog channel. Meanwhile, KSI amassed a fan base through his participation in FIFA. The two would get into a battle involving diss tracks aimed at each other. The diss tracks were released in the run-up to Logan Paul's first fight with KSI. The fight took place in Manchester, England, and it was a huge success. Paul had never fought before, but KSI had fought another YouTuber, Joe Weller.
Both fighters made their professional debuts in the second fight. KSI-Paul II headlined an event put on by Matchroom Boxing's Eddie Hearn at the Staples Center. On the undercard were WBO Super Middleweight Champion Billy Joe Saunders and WBC Lightweight Champion Devin Haney. The main event resulted in a split decision in favour of KSI. Paul defeated KSI in the fourth round, but he was docked two points for hitting him on the way down.
In a joint statement, they said: "Our goal was to create a fantastic hydration drink that can fuel any lifestyle. Over the past year, we've worked countless hours to formulate the product from scratch, lock in deals with the largest retailers in the world and build a multi-hundred-person team to get our products to the shelves. We're humbled by the process of creating a real brand and look forward to competing with some of the biggest beverage companies in the world. As underdogs, we always cherish the opportunity to show the world what's possible. Now that we're both fighting for the same team, we truly believe the sky is the limit."
