Musk Admits xAI 'Wasn't Built Right' as 10 of 12 Co-Founders Leave

Elon Musk's AI startup xAI is in full crisis mode. Only 2 of the original 12 co-founders remain after Musk pushed out two more this week, frustrated with the company's coding product progress. He has publicly admitted xAI "wasn't built right the first time" and brought in "fixers" from SpaceX and Tesla to audit the company. For a startup valued at $250 billion, losing 83% of your founding team is a remarkable achievement.

The Co-Founder Exodus

The latest departures include Zihang Dai and Guodong Zhang, who headed xAI's Imagine team. Zhang reportedly left after being blamed for issues with the coding product and was relieved of his primary duties by Musk. The pattern is familiar to anyone who has watched Musk's management style: bring in talented people, set aggressive deadlines, blame them when things don't move fast enough, and bring in replacements from his other companies.

The exits leave xAI with just two of its original co-founders — a stunning attrition rate for a three-year-old company. In any other context, losing 10 of 12 founders would be considered a catastrophic failure of leadership. In the Musk universe, it's just another Tuesday.

SpaceX and Tesla "Fixers" Arrive

Rather than reflecting on why talent keeps fleeing, Musk has deployed executives from SpaceX and Tesla to parachute into xAI. These "fixers" have been evaluating employees and firing those deemed inadequate. The approach mirrors what happened at Twitter (now X) after Musk's acquisition: rapid-fire terminations based on snap judgments from outsiders who don't fully understand the domain.

Musk told remaining xAI staff that the company needs to be "rebuilt," saying it was "not built right the first time." This admission is particularly awkward given that Musk personally recruited each of those 12 co-founders and set the company's direction from day one.

The $250 Billion Valuation Question

The chaos comes at an awkward time. xAI was recently merged with SpaceX in a deal that valued the AI company at $250 billion — part of a combined entity valued at $1 trillion as SpaceX prepares for what could be a record-breaking IPO. Investors paying $250 billion for an AI company might reasonably expect it to have, at minimum, a stable founding team.

The valuation is especially hard to justify when Musk himself admits the company wasn't built correctly. Tesla invested $2 billion in xAI just weeks before the admission — raising questions about whether Tesla's board conducted adequate due diligence.

The Bottom Line

xAI's co-founder exodus is a masterclass in how not to build an AI company. Musk's pattern — recruit top talent, impose impossible timelines, blame the team when reality doesn't match his vision, then replace them with loyalists from his other companies — has played out at Twitter, Tesla, and now xAI. A $250 billion AI company with only 2 of 12 original co-founders, publicly declared "not built right" by its own CEO, and being audited by people from a rocket company and a car company. What could possibly go wrong?
