# River AI raises $1.1B seed round led by General Catalyst

> River AI has pulled off one of the largest seed rounds on record, raising $1.1 billion led by General Catalyst just two months after emerging from stealth in June. Chipmakers Nvidia and AMD Ventures joined, an unusual pairing that hints at how much compute the company expects to burn. The founder is Igor Babuschkin, a co-founder of xAI with prior stints at DeepMind and OpenAI, and pedigree clearly did a lot of work here. The company is building reinforcement learning infrastructure meant to let enterprises train their own AI agents, rather than depend on a closed model from a big lab. Its pitch is speed and cost: an API that River says can complete complex RL runs in 15 to 20 minutes at two to four times lower cost than closed-source alternatives. A billion-dollar seed for a two-month-old startup is a jaw-dropping number, a sign both of how hot trainable-agent infrastructure has become and of how much investors will pay to back a proven founder before anyone else can.
