Former xAI co-founder Igor Babuschkin has made a serious entrance with his new project — River AI.
The company, all of two months old, raised an eye-watering $1.1 billion in seed funding. The round was led by General Catalyst and AMP PBC.
The most interesting detail is who else showed up: Nvidia and AMD Ventures in the same round, alongside Y Combinator and Temasek. Having both major chipmakers at the table sends a clear signal — this startup won't be scrambling for compute anytime soon.
The pitch: the market is getting tired of closed corporate AI ecosystems. River AI is betting on "Personal AI," open-weight models, and data sovereignty. The project's core goal is to break the big labs' monopoly and give both enterprises and regular users full control over their own models — from hardware all the way down to training data. The startup offers its own API that lets developers run complex fine-tuning (including reinforcement learning) in 15–20 minutes without a dedicated infrastructure team, which the company claims is 2–4x cheaper than closed alternatives.
Why it matters: this is a strong signal of a narrative shift in the industry. Smart money — and serious budgets — are moving away from closed proprietary systems toward personalized, decentralized, user-controlled neural networks. Given Babuschkin's background building models at Google DeepMind, OpenAI, and xAI, launching River AI is a genuine bid to rewrite the market's architecture.
