Igor Babushkin, one of xAI’s cofounders and a veteran of OpenAI and Google DeepMind, has launched a new startup called River AI, aiming at personalized AI that users can train, steer, and keep under control rather than hand over to a black box.
Babushkin left xAI in 2025 to focus on his own ventures, and River AI is already staffed with more ex-xAI talent, plus former Tesla employees who worked on AI for autopilot systems. The startup is betting that AI agents and real-world autonomy will converge, even as the industry argues over whether AI is a job-stealer or a helper.
River AI’s pitch: user-controlled AI agents
According to Babushkin, River AI will build AI agents that learn from their owners and operate as if a person were supervising them all the time. In practical terms, the software is meant to reflect a user’s style, preferences, and goals, which is a cleaner sales pitch than the usual ”general intelligence” sermon. It also puts the startup in a crowded race, where everyone wants to sound like the future and nobody wants to admit how messy the product is likely to be.
- Focus: personalized AI agents
- Goal: user training and user control
- Future plan: hardware for ”physical AI”
Why personalized AI is the safer bet
Babushkin says the company was partly inspired by growing anxiety that AI will replace workers. That is the obvious opening for any startup pitching augmentation instead of replacement, but it is also commercially smarter. Enterprise buyers and consumers are far more likely to pay for tools that make them faster, more consistent, and less replaceable than for grand promises about artificial superintelligence.
The broader question is whether River AI can turn a familiar idea into a product people actually trust with their habits, preferences, and decisions. If it can, it may have a better shot than companies still pretending every AI user wants a digital overlord. If it cannot, it will join the long list of startups that learned the hard way that personal is a lot harder to ship than powerful.
Another xAI breakup, another AI startup
xAI has been leaking talent for a while. Since the company’s move under the SpaceX umbrella, dozens of specialists have left, including almost all of the original cofounders from 2023. Elon Musk has said the combined company will be restructured ahead of an IPO, which is exactly the sort of moment when startup cultures start to fray and ambitious employees decide to build their own thing instead of waiting for the boss to rearrange the furniture.
River AI is not alone. Other former xAI staffers have already surfaced at new AI ventures such as Humans&, reinforcing a broader trend: the people who built the models are now trying to own the user layer, not just the underlying engine.
