# River AI Secures $1.1B Seed Round From General Catalyst Led by Igor Babuschkin

> River AI has raised a startling 1.1 billion dollar round, blurring the line between seed and Series A, led by General Catalyst and AMP PBC. The cap table reads like a who's who, with Nvidia, AMD Ventures, Y Combinator and Temasek all joining a company only a couple of months old. The draw is the founder and the thesis. CEO Igor Babuschkin is an xAI co-founder with earlier stints at DeepMind and OpenAI, and River is building infrastructure that lets enterprises fine-tune open models for themselves, using reinforcement learning and LoRA-style techniques exposed through an API. A ten-figure raise before there is much product is a bet on pedigree and on a specific wager: that the next phase of value shifts from a handful of giant closed models toward companies customizing open ones for their own data and workflows. If that thesis holds, River is early. If it does not, this is a lot of capital chasing a founder's reputation.
