Jan Gustafsson

Jan Gustafsson is a German chess Grandmaster, commentator, and entrepreneur who co-founded Chess24, one of the most ambitious chess platforms ever built. Chess24 ran from 2014 until its closure in January 2024, and during that time Jan was a central figure in its broadcasts and content. He has since continued streaming and commentating, including hosting Banter Blitz on Chess.com's channels following the platform migration.

Jan is perhaps best known to competitive chess fans as a three-time preparation second for Magnus Carlsen, working on his World Championship teams in 2016, 2018, and 2021. He also worked with Ian Nepomniachtchi's team during the 2024 FIDE Candidates. His deep theoretical knowledge, particularly in the Sicilian Defense and 1.e4 systems, makes him one of the most sought-after opening analysts in the game. He has published multiple opening repertoire courses on Chessable.

On the national level, Jan has served as coach of the German national chess team, including at the 2022 Chess Olympiad. He earned his Grandmaster title in 2003 and has been a consistent presence in European chess since then. His Twitch channel, gmjangustafsson, has become the primary destination for German-language chess streaming, with a loyal audience that follows him for both top-level commentary and his own blitz games.

Jan's combination of competitive credentials, broadcasting experience, and coaching work places him among the most well-rounded figures in the global chess media landscape.
