Jens "Jeb" Bergensten[3] (born 18 May 1979)[1][2] is a Swedish video game designer. Since December 2010, he has worked for the video game developer Mojang as a programmer and game designer. He became the lead designer and lead developer of the indie sandbox game Minecraft, after Markus "Notch" Persson stepped down from his position in December 2011.[4][5] He is known by his in-game name "jeb_".


Bergensten started programming his first games at age 11 using BASIC and Turbo Pascal.[6] By age 21, he was a mapper and modder for the first-person shooter Quake III Arena.[7] Later he worked as a C++ and Java programmer for the game developer Korkeken Interactive Studio, which went bankrupt and became Oblivion Entertainment.[8] During that time he led the development for the online role-playing game Whispers in Akarra, which he later discontinued after straying from the team's original creative vision for the project.[9]

After the insolvency of Oblivion, Bergensten moved to Malmö and earned a master's degree in computer science at Lund University in 2008.[6][10] During his studies he founded the indie game development company, Oxeye Game Studio, along with Daniel Brynolf and Pontus Hammarber. The studio became known for the platform game Cobalt and the real-time strategy game Harvest: Massive Encounter.

Until 24 November 2010, Bergensten worked for the online knowledge community, Planeto.[11][12]


Bergensten was originally hired as Mojang's backend developer for Scrolls, but began programming more and more significant parts of Minecraft until he took over its development completely on 1 December 2011 after Markus Persson stepped down from this position.[5] Bergensten was part of the team that developed Catacomb Snatch as part of the Humble Bundle Mojam event where game developers create a game from scratch in 60 hours. He has also attended many Game jams with Mojang.
