Jason Holtman, the former director of business development for Valve who joined Microsoft last year to focus "on making Windows a great platform for gaming and interactive entertainment," has left the company after six months, Microsoft confirmed to Polygon today.
"We can confirm that Jason has left Microsoft and we're grateful for his time at the company," a Microsoft spokesperson said in a statement. "We wish him the best in his future endeavors."
Last year, Holtman told GamesIndustry International he joined Microsoft to help bolster the company's PC gaming efforts.
"I think there is a lot of opportunity for Microsoft to deliver the games and entertainment customers want and to work with developers to make that happen," he said at the time, "so I'm excited to be here."
Prior to moving to Microsoft, Holtman worked at Valve for close to eight years, focusing on the licensing business for Steam, the Source engine and Valve's internally developed games.
Polygon has reached out to Holtman for comment on the move.
