Good morning. I’ve been writing about the uptick in
CFO turnover. The latest high-profile departure is at multibillionaire Elon Musk’s xAI.
Mike Liberatore stepped down abruptly as the finance chief of Musk’s artificial intelligence startup,
according to a report from The Wall Street Journal citing anonymous sources. Liberatore was hired in April and reportedly left in late July. The reasons for his departure are not known, but he followed other high-profile exits from xAI of late. The company did not immediately respond to my request for comment.
Before joining xAI, Liberatore worked at
Airbnb for almost nine years—most recently as VP of finance and corporate development—and had previously served in several business unit CFO roles. He’s also worked at
Intel,
eBay, and PayPal. During his brief tenure at xAI, he reportedly helped raise $10 billion in funding and expanded data center operations.
Launched by Musk in July 2023, xAI is a
competitor of OpenAI. Both companies develop large language models and AI assistants—OpenAI with ChatGPT, xAI with Grok—that target overlapping user bases.
Liberatore’s departure follows a wave of exits, including cofounder Igor Babuschkin (who left to start a VC firm focused on AI safety), General Counsel Robert Keele after one year, and senior lawyer Raghu Rao. xAI’s leadership is highly centralized under Musk, with no publicly disclosed independent board.
Michael Morris, a professor at Columbia Business School, shared his assessment with me. He noted that Keele cited differences in worldview with Musk and family priorities in his LinkedIn
post about leaving. Of course, Musk also played a key role in the Trump White House earlier this year.
Morris also observed that executive turnover among Musk’s direct reports at
Tesla is 44%, compared to about 9% at
Meta,
Amazon, and Netflix; overall, Tesla’s executive turnover rate is 27%, nearly double the industry average.
“Analysts point to Musk’s demanding, high-contact leadership style—managing up to 18 direct reports at once—as a key reason for the trend,” Morris said. “This pattern is visible not only at Tesla but also at X and xAI, suggesting structural factors rather than isolated events.”
He added that many executives leave rather than risk being blamed when new initiatives encounter regulatory hurdles: “Executives don’t want to become the ‘fall guy.’”
What fuels mass exits?xAI isn’t alone in seeing mass executive departures. Last year, OpenAI also saw
multiple senior departures—such as cofounder John Schulman and
CTO Mira Murati. Also in 2024, at the DNA testing startup 23andMe, all seven independent
directors resigned simultaneously, citing major disagreements with CEO Anne Wojcicki and her plans to take the company private.
Frequent executive departures often indicate strategic misalignment or a resistant company culture, especially in founder-led startups and fast-moving AI companies, Martha Heller, CEO of technology executive search firm
Heller, told me.
“In AI-focused companies, the very public failures of new large language models and uncertainty over true AI ROI can create an additional layer of finger-pointing, further upsetting leadership stability,” Heller said.
Robert Kelley, professor of management at Carnegie Mellon University’s Tepper School of Business, explained that if top-level executives are continually leaving, “it’s a vote of no confidence in either the CEO, the board, or the strategy of the company.”
It’s unusual at startups for most executives to just walk away in a short period of time, Kelley said. Most people who join do so because they believe in the company and also think there’s going to be a big payoff, he explained.
To stem disruption, if a notable number of executives leave a company, transparent communication to customers and employees is key, Heller said.
And the CEO of the company should also “take a look in the mirror and ask the hard question, ‘Am I the problem?’” Kelley said.
