Ross Nordeen, a 36-year-old Michigan Tech graduate, has left xAI, marking the last departure of Elon Musk's original co-founding team. Nordeen, who reported directly to Musk, served as the primary operational lieutenant, coordinating priorities and driving execution across multiple workstreams.

Nordeen's Background

Nordeen's history with Elon Musk stretches back to his time at Tesla, where he worked as a technical program manager on the Autopilot team. He also played a central role in building out the data centers used to train Tesla's Full Self-Driving system. Nordeen is a longstanding friend of Musk's cousin, James Musk.

The exodus from xAI's founding team has been swift and striking, with eight co-founders departing since January. Among those who have left are Manuel Kroiss, who led pretraining, and reported directly to Musk, and Guodong Zhang, Zihang Dai, Toby Pohlen, Jimmy Ba, Tony Wu, and Greg Yang.

Timing of Departures

Most departures began accelerating in the weeks following SpaceX's merger with xAI in February. This structural upheaval has unfolded in parallel with Elon Musk's preparations for SpaceX's blockbuster IPO.

Restructuring at xAI

Elon Musk has acknowledged that xAI "was not built right first time around," and has stated that the company is being rebuilt from the foundations up. xAI has undergone several restructurings since and has shed dozens of employees over the past few months. Teams working on Grok Imagine and Macrohard, xAI's video and image generation tool and AI agent project, were among those cut earlier this year.

Challenges Ahead

Despite its enormous war chest and headline valuation, xAI faces a genuine competitive gap. The company trails behind rivals OpenAI and Anthropic in terms of scale, user reach, and product penetration, a challenge that its ongoing restructuring will need to address if it is to close the distance before the IPO window opens.
