Ross Nordeen, a key figure in Elon Musk's AI startup xAI, has left the company, marking the departure of all 11 co-founders. According to PANews, Nordeen, who was 36 years old, worked closely with Musk, coordinating priorities and driving the execution of various company tasks. The departure follows the merger of xAI with SpaceX in early February, which led to a significant exit of co-founders. Earlier this month, Musk commented that xAI was initially not structured correctly and is undergoing a foundational rebuild.
