River AI Raises $1.1B Led by General Catalyst and AMP PBC to Build Open AI Stack
Founded by xAI co-founder Igor Babuschkin, River AI gives developers and enterprises the tools to train, tune, and own custom AI models
River AI, the full-stack AI company founded by xAI co-founder Igor Babuschkin, today announced $1.1 billion in funding, led by General Catalyst and AMP PBC with strategic investment from NVIDIA and AMD Ventures. Additional investors include Y Combinator and Temasek. The round will accelerate River AI's mission to build powerful personal AI and to give developers and companies the tools to train, tune, and serve their own AI models, putting ownership of AI directly in the hands of the people and organizations who use it.
Today, most companies using AI are running general-purpose models trained on the entire internet and designed for the broadest possible audience. They are powerful, but they are not built for any one organization in particular. Until now, building a custom model required a dedicated infrastructure team, specialized hardware, and months of work, putting it out of reach for most companies.
With River's API, any enterprise can complete a complex reinforcement learning training run in 15 to 20 minutes with no infrastructure team required, at two to four times the cost savings relative to closed-source alternatives.
