Six of 12 co-founders gone as Elon Musk frames exits as scaling pains — and pushes aggressive hiring
Elon Musk is moving to contain the narrative around a growing wave of departures at xAI, including two more co-founders who exited this week.
That brings the total to six out of the original 12 co-founders now gone — alongside at least 11 engineers who have publicly announced exits in recent days.
At an all-hands Tuesday, Musk said the changes reflect scale, not performance.
“We’ve reached a certain scale,” Musk said, according to The New York Times. “Some people are better suited for the early stages of a company and less suited for the later stages.”
On X a day later, he was more direct.
“This unfortunately required parting ways with some people.”
In short: this was push, not pull.
The Reorganization — and the Recruiting Pitch
Musk said xAI reorganized “to improve speed of execution,” arguing fast growth demands structural change “like any living organism.”
He added the company is “hiring aggressively.”
Then came the Musk flourish: “Join xAI if the idea of mass drivers on the Moon appeals to you.”
The message is clear — reset the structure, refill the ranks, move faster.
But losing half your founding team in a short window inevitably raises questions.
Who’s Leaving — and Why
Among the high-profile exits:
- Yuhuai (Tony) Wu, co-founder and reasoning lead
- Jimmy Ba, co-founder and research/safety lead
- Shayan Salehian, product infrastructure and model behavior
- Vahid Kazemi, machine learning PhD
- Roland Gavrilescu, former engineer
- Several additional engineers across multimodal, RL, and product teams
At least three departing staffers have said they’re starting something new together. Others hinted at preferring smaller, autonomous teams to build frontier AI more rapidly.
Kazemi put it bluntly: “All AI labs are building the exact same thing, and it’s boring.”
Wu framed it as opportunity: “A small team armed with AIs can move mountains.”
That sentiment lands at a moment when lean AI startups can punch above their weight, thanks to accelerating model capabilities.
Controversy Clouds the Moment
The exits come amid broader turbulence.
xAI is under regulatory scrutiny after Grok generated nonconsensual explicit deepfakes of women and children that spread on X. French authorities recently raided X offices as part of an investigation.
The company is also moving toward a planned IPO later this year, after being legally acquired by SpaceX last week.
Separately, Musk faces personal controversy following Justice Department files detailing past email exchanges with Jeffrey Epstein, including discussions of potential visits in 2012 and 2013.
Optics vs. Impact
With more than 1,000 employees, xAI’s short-term capabilities likely remain intact.
Online, the episode snowballed into meme territory, with users jokingly announcing they were “leaving xAI” despite never working there.
Still, forced co-founder exits rarely signal frictionless scaling.
Several engineers followed the founders out the door. At least three are launching something new together. In frontier AI, where elite talent is scarce and reputation compounds, retention matters.
As xAI competes with OpenAI, Anthropic, and Google, the test isn’t just model performance — it’s whether Musk can build a durable research culture while reorganizing at breakneck speed.
Is this disciplined evolution — or early warning tremor?
TL;DR:
Elon Musk says recent xAI departures — including six of 12 co-founders — stem from a company reorganization, not voluntary exits. At least 11 engineers have left in recent days, some to launch new ventures. The shake-up comes amid regulatory scrutiny and IPO plans.
