Aug 14, 2025 — Igor Babuschkin, a co-founder and engineering lead at Elon Musk’s AI startup xAI, has exited the company to start Babuschkin Ventures, an investment effort he says will fund AI-safety research and back “humanity-advancing” startups. He announced the move in a post on X on Wednesday.

Key facts

• Who: Igor Babuschkin, among the earliest technical leaders at xAI and previously a researcher at DeepMind (AlphaStar) and OpenAI.
• What: Leaving xAI to found Babuschkin Ventures, focused on AI safety and responsible development.
• When: Announced August 13, 2025 (U.S. time).
• Why it matters: Leadership changes at frontier labs can influence product velocity, safety priorities, and hiring roadmaps. Independent outlets also confirmed the departure.

What he said

In his farewell note, Babuschkin called xAI a company he “helped start with Elon Musk in 2023,” and reflected on two lessons learned from Musk: roll up your sleeves on technical problems and maintain a “maniacal sense of urgency.” He framed the new fund as a way to accelerate safe, socially beneficial AI.

xAI backdrop

The exit follows a high-profile stretch for xAI’s Grok products. Recent reporting scrutinized a “spicy” setting in Grok Imagine, a video feature that enabled explicit celebrity deepfakes, prompting questions about content safeguards. Separately, the company’s Memphis supercomputer project has drawn environmental-impact scrutiny amid permitting and community pushback.

Background on Babuschkin

Before xAI, Babuschkin worked on DeepMind’s AlphaStar program and earlier spent time as a researcher at OpenAI—experience that placed him among the small cohort of engineers with large-scale model-training expertise. At xAI, he led engineering teams as the company scaled its Grok model family.

What’s next

• For xAI: Watch for how the company backfills Babuschkin’s responsibilities and whether near-term releases emphasize tightened safety defaults in Grok and related features.
• For Babuschkin Ventures: Early investments will signal focus areas—e.g., evaluation tooling, red-teaming infrastructure, content-safety pipelines, and reliability/monitoring stacks.
