Igor Babuschkin, co-founder of Elon Musk’s artificial intelligence startup xAI, has stepped down to start a new venture capital firm aimed at enhancing AI safety and funding high-impact technology projects.
“Today was my last day at xAI, the company that I helped start with Elon Musk in 2023,” Igor Babuschkin announced on Wednesday in a post on X. “I still remember the day I first met Elon, we talked for hours about AI and what the future might hold. We both felt that a new AI company with a different kind of mission was needed.”
The engineer, who previously worked on AlphaStar at Google DeepMind and held research roles at OpenAI, was key in building xAI into a major player in the sector in less than two years.
He oversaw infrastructure, product and applied AI projects, and played a central role in constructing the company’s Memphis, Tennessee supercomputer, completed in just 120 days, despite industry veterans calling the goal “impossible.”

Babuschkin recalls one defining moment during that build, when a late-night debugging session with Musk led to the discovery of a critical BIOS setting error. “I learned 2 priceless lessons from Elon: #1 be fearless in rolling up your sleeves to personally dig into technical problems, #2 have a maniacal sense of urgency,” he wrote.
His time at xAI comprised of rapid technical achievement but also controversy. The company’s Grok chatbot has faced repeated public backlash, ranging from inserting extremist conspiracy theories into responses to antisemitic rants, to enabling the creation of AI-generated nude videos of public figures such as Taylor Swift. Grok was even suspended from X earlier this year for inflammatory political claims.
Environmental concerns have also followed xAI’s expansion. The Memphis supercluster, dubbed “Colossus”, is powered by 35 methane gas turbines. Local residents and advocacy groups, including the NAACP, have filed appeals over increased air pollution in majority-Black neighbourhoods.
A University of Tennessee study reported nitrogen dioxide levels near the site had risen by 79%, with local asthma cases spiking in the nearby Boxtown community.
Despite these challenges, Babuschkin describes his departure with affection. “As I drive away today, I feel like a proud parent, driving away after sending their kid away to college,” he said. “My heart is brimming with tears of joy, rooting for the company as it grows and matures.”
His new firm, Babuschkin Ventures, will fund startups developing AI systems aligned with human values, and will support research into AI safety. He says the inspiration came from a recent dinner with Max Tegmark, founder of the Future of Life Institute, where they discussed how to ensure “our children can flourish” in a world with advanced AI.
“The singularity is near, but humanity’s future is bright,” Babuschkin stated, noting his belief that safe, beneficial AI could help unlock solutions to some of the world’s most profound scientific problems, including quantum gravity and the Riemann hypothesis.
