Nous Research raises $90M Series B at $1.5B valuation to build Hermes Agent
According to The Wall Street Journal, open-source AI company Nous Research has closed a $90 million Series B round at a $1.5 billion valuation. The funding was directly triggered by explosive usage of its open-source Hermes Agent, and the capital will go toward advancing the Hermes Agent project and building a mobile app.
Confirmed
- The round is $90 million at a $1.5 billion valuation, figures given by Teknium and echoed across multiple reposts.
- The investor lineup includes NVIDIA, M12 (Microsoft), Samsung Next, Robot Ventures, USV, Y Combinator, Menlo Ventures, among others.
- The trigger was surging usage of the open-source Hermes Agent, which has logged 22.7 million downloads since February.
- Funds are explicitly earmarked for pushing the Hermes Agent project forward and developing a mobile app.
- The post also cited the company's annualized revenue as of mid-September, but the original summary was truncated and the exact figure is incomplete.
Why it matters
- Nous Research built its name on open source, and this round shows open-source agent projects can still command big bets from top-tier institutions (NVIDIA, Microsoft's M12, etc.).
- The mobile app plan signals Hermes Agent moving from a developer tool toward a consumer-facing product—a key marker of its commercialization path.
