Grzesiek started his CS:GO career with several ESEA teams, particularly Exertus and Manajuma. He was soon acquired by CompLexity Gaming as a stand-in, and signed with Cloud9 in August 2014 when CompLexity was acquired by Cloud9. He helped lead Cloud9 to 2nd place in ESL One Cologne 2017 and a first place finish at ESL Pro League Season 4 in 2016. On August 16, 2017, he announced that he would be stepping down from the Cloud9 team, but that he and n0thing would remain as substitutes on the "bench". On April 18, 2018, Grzesiek left Cloud9 and professional CS:GO entirely. He occasionally plays CS:GO with Old Guys Club. He also participated in PlayerUnknown's Battlegrounds "Twitch Rivals" tournament, with his duo team placing second and winning a $5,450 prize. Since transitioning from being a competitive CS:GO player to a full-time streamer on the streaming platform Twitch, Grzesiek has maintained a diverse set of games. As of May 2020, he has streamed for over 7,000 hours on the platform, and has acquired over 364 million total views. On March 10, 2019, at 12:02am he reached 100,000 Twitch subscribers—and gained another 14,000 the next day—making his subscriber count more than double the runner up streamer at the time: TimTheTatman. He continued to stream full-time on Twitch until October 2019. On October 24, 2019, Grzesiek officially announced his move from Twitch to Mixer and would be broadcasting exclusively on Microsoft's streaming platform, following the steps of fellow streamer Tyler "Ninja" Blevins, who announced a similar deal earlier that year. This decision surprised his fans, as he previously stated "Hey man, Ninja's gone... It's all me, baby. Gotta take advantage." He claimed "I just thought it was the best move for my career." And though he has seen a decrease in numbers from his Twitch days, he is enjoying himself and the games he plays, and feels welcomed not only by the platform itself, but by the community and fans that followed him on his move to Mixer. On June 22, 2020, Microsoft announced that it would be shutting down its streaming platform Mixer and instead has become a partner with Facebook Gaming. It was alleged that Grzesiek received an offer from Facebook Gaming that would have financially exceeded that of Mixer. Grzesiek has since declined the offer, and received the remainder of the current contract payout. Grzesiek released a statement via his Twitter account saying, "I appreciate the Mixer community and everything I’ve been able to do on the platform. I love you guys and am figuring out my next steps."
