xAI's Last Remaining Cofounder Just Walked Out the Door
Ross Nordeen, the final original cofounder at Elon Musk's AI venture, has departed the company.
xAI now has zero cofounders left. Ross Nordeen, the last of the original eleven who launched the company alongside Elon Musk in 2023, exited on Friday.
Nordeen wasn't just any cofounder. He served as Musk's right-hand operator, reporting directly to the CEO. His departure marks the end of an era — every single person who helped start xAI alongside Musk has now moved on.
When Musk founded xAI in 2023, he assembled a team of 11 cofounders to take on the AI industry. That roster has steadily dwindled to zero. The company, which has grown into a major player in the generative AI space, now operates without any of its founding team beyond Musk himself.
No word yet on what prompted Nordeen's exit or where he's headed next.
