General Catalyst leads $1.1B round into 2-month-old River AI | TechCrunch
Igor Babuschkin

Good Morning,

Visions of AI is a new feature format I’m experimenting with that will amount to a short profile on an AI or emerging tech startup. The cadence of this style of article is unknown as of yet, but there are a lot of fascinating startups I want to share about.

This is designed to be light evening reading to go out at a time-slot of 8 pm EST.


Not that many AI researchers have worked at Google DeepMind, OpenAI, xAI and started their own companies. Igor Babuschkin in 2026 is the founder of River AI. River is building a stack for personal AI that is both open-source and adapts to you. This is a bit like the holy grail of personalization combined with all the recent advances in AI.

I actually find myself attracted to the philosophy and goal of the startup:

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.

This has legit open-source vibes to me and the interview with the lead investor General Catalyst felt authentic:

River AI is Hiring

The interview is with Hemant Taneja, the CEO of General Catalyst, one of the lead investors of the Seed/Series A.

A 2-Month old Startup

River AI is among a group of AI labs that are taking on hard problems with quick capital not seen previously in the history of Venture Capital. It’s also very clearly a bet on Open-Source American AI.
