In 2011 Colin found his way to YouTube, at first simply as an outlet for his creativity. Combined with his love for the game League of Legends he expanded his own channel Koolein and grew to be one of the more well known names of his generation.
In 2017 Colin left YouTube behind and made the leap to Twitch, where he started to focus more on esports. His interest in esports has only grown since then and Colin has visited several events, such as IEM, Worlds 2016 and ESL One.
In november 2017 he became a reporter at ESL Benelux Winter 2017, which led to him being asked more and more as a desk host and since then he has hosted numerous events.
Colin also has a background in radio and has voiced several characters in animation movies, including the Dutch version of Angry Birds.
