He later made the transition in Dota 2 and has played in several European teams, mostly all-Danish teams such as Meet Your Makers and Danish Bears and a short stint in Cloud 9 for a few years before arriving at their carry player for Team Secret in August 2017. Since his addition to the squad, he has provided Team Secret several tournament victories in the current 2017-18 Dota Circuit and resurged Team Secret's performance in the competitive circuit.

He continued to play in various Danish teams for a few years before joining Danish Bears in August 2015.
