Two-month-old River AI raises $1.1B seed/Series A led by General Catalyst

General Catalyst leads $1.1B round into 2-month-old River AI

River AI, founded by xAI co-founder Igor Babuschkin, raised $1.1B just two months after launch. General Catalyst and AMP PBC led the round, with Nvidia, AMD Ventures, Y Combinator, and Temasek joining. Babuschkin, formerly at DeepMind and OpenAI, wants to rebuild the full AI stack—training, models, product, and hardware—to create personally trainable agents that act as 'guardian angels' rather than worker replacements. The company exited stealth in June and already offers a per-token API. The post does not disclose valuation, model specs, or hardware details.

Why it matters: xAI co-founder spinout lands $1.1B at two months old with both NVIDIA and AMD on the cap table — a top-tier team and capital signal. Held below 85 because the post doesn't disclose any product or technical direction yet.
