### His Start-Up’s Goal: A.I. That Is Trainable and Not Controlled by a Big Company

LinkedIn · River AI

Today, we're sharing that River AI has raised $1.1 billion, led by General Catalyst and AMP PBC with strategic investment from NVIDIA and AMD. Additional investors include Y Combinator and Temasek. We imagine a future where your AI works entirely for you and deeply aligns with your values. Compared to the corporate chatbots of today, it will feel completely different: responsible, curious, and truly yours. Most importantly, you'll own everything: the hardware it runs on, the data it learns from, and the intelligence itself. Our training API is already live and powering incredible work today. This new funding accelerates our push to bring the full personal AI stack to life. Read River AI CEO Igor Babuschkin’s conversation with the New York Times to learn more: https://lnkd.in/gWFz-rrN
