Elon Musk’s last co-founder reportedly leaves xAI
Earlier this month, it looked like all but two of Elon Musk’s 11 co-founders at his AI startup xAI had
departed the company
. Now, according to Business Insider, the remaining two co-founders, Manuel Kroiss and Ross Nordeen, have left as well.
BI said on Wednesday that Kroiss had
told people that he’s leaving xAI
, then reported that
Nordeen left the company on Friday
.
Musk recently claimed xAI “was not built right [the] first time around,” so it’s now “being rebuilt from the foundations up.” The company was recently
acquired by Musk’s SpaceX
, bringing SpaceX, xAI, and X (
formerly Twitter
) together under one corporate umbrella, all as SpaceX is reportedly
planning to go public
.
Kroiss and Nordeen both reported directly to Musk, according to BI, with Kroiss leading the company’s pretraining team, while Nordeen was Musk’s “right-hand operator.” Nordeen reportedly came to xAI from Tesla, and was involved in planning major layoffs at Twitter after Musk acquired the company in 2022.
TechCrunch has reached out to xAI for comment.
