Jonas Mårtensson
Jonas Mårtensson was the strategy director of Mojang Studios.[verify] He joined the company as vice president on October 2, 2013, when his twin brother and then-CEO of Mojang, Carl Manneh, announced his recruitment.[1] With the acquisition of Mojang by Microsoft in November of 2014 and the subsequent retirement of his brother, he assumed the position of CEO.[2]
A few months back I had a casual conversation in the office kitchen talking about the insane amount of things going on at Mojang. I said something in the lines of 'I wish I could clone myself'. I remember Tobias mumbling something like 'I’ll look into that'. Yesterday Tobias came back to me and said he had something to show me. Introducing Mojang’s new Vice President: Jonas Mårtensson! Sometimes it’s just nice to be able to clone yourself… or hire your twin brother.
He left Mojang in September 2024.[3]
