Toby Pohlen Leaves xAI After Merger with SpaceX

Co‑founder of the company xAI, Toby Pohlen, announced his departure from the startup that develops artificial intelligence technologies. This is not the first time – more than ten founders have left the company within its first three years.

What Happened
- Pohlen’s Last Day

In a post on social network X (formerly Twitter), Pohlen noted: “Today was my last day at xAI.” He added that he plans to rest and “think about what I want to do next.”

- Thanks

Pohlen expressed gratitude to Elon Musk for “bringing me onto the team.” In response, Musk wrote a thank‑you message: “Thanks for helping develop xAI.”

Who Has Already Left xAI
Year | Departing | Reason (if specified)
2024 | Kyle Kosich – 2023 | Igor Babushkin – 2023 | Christian Segedi – January 2024 | Greg Yan – Resignation due to health | February 2024 | Jimmy Ba – February 2024 | Tony Wu –

Pohlen became the seventh of twelve founders to leave the company in its first three years.

What Happened After the Merger
- Combined Valuation

After xAI and SpaceX merged, the combined business was valued at $1.25 trillion.

- AI Division Restructuring

As part of the reorganization, Pohlen was appointed head of the Macrohard division – a unit focused on developing software using artificial intelligence. The name references Microsoft and is a play on words.

- SpaceX IPO

SpaceX is preparing for an initial public offering (IPO) that promises to be the largest in stock market history.

Thus, Toby Pohlen’s departure marks another phase of xAI’s transformation after merging with SpaceX and opens new prospects for both companies.
