# River AI Raises $1.1B at ~$5B Valuation for Personalized AI Training

> River AI has raised $1.1 billion in a round led by General Catalyst and AMP PBC, valuing the two-month-old company at around $5 billion. That is a staggering figure for a startup this young, and it reflects both the pedigree of the founder and investor conviction in his pitch. River is the new venture of Igor Babuschkin, a co-founder of xAI with prior stints at DeepMind and OpenAI, who has reportedly committed up to $100 million of his own capital. Nvidia, AMD Ventures, Y Combinator and Temasek joined the round. The company aims to let enterprises train and own personalized AI models using reinforcement learning, rather than renting general-purpose systems from the big labs. It is a bet that serious buyers will want models tuned to their own data and under their own control. The valuation is a lot to grow into on the strength of a founder's reputation, but in the current market a proven name and a clear enterprise story is apparently enough to command billions before shipping much.
