Nous Research bets open-source agents can win: Hermes hits 214k stars, $1.5B valuation
Open-source AI lab Nous Research is closing a $75M+ round at a $1.5B valuation after its Hermes agent hit ~214,000 GitHub stars and ~40,000 forks.
Nous Research
What the business is
Nous Research is an open-source AI lab best known for Hermes, a locally run AI agent with built-in skills that users can run free on their own machines or rent as a cloud service for $20-$200 a month.
Starting capital：About $70M raised before 2026, including a $50M Series A led by Paradigm (April 2025)
How it started
Nous Research was founded in 2023 by Jeffrey Quesnelle, Karan Malhotra, Ryan Teknium and Shivani Mitra as an open-source AI lab, later known for coding and math models and for the Hermes agent. Before the 2026 round it had raised about $70 million from backers including Paradigm, Robot Ventures, North Island Ventures, Delphi Ventures, OSS Capital and Balaji Srinivasan, including a $50 million Series A led by Paradigm in April 2025.
What happened
Weeks after OpenClaw's locally run agent went viral, Nous released Hermes, an agent that runs on a desktop or VPS with built-in skills such as web search, coding and image understanding, and is designed to learn from usage and build new skills without manual intervention. Hermes grew to roughly 214,000 GitHub stars and nearly 40,000 forks, with users automating tasks and messaging agents through Telegram and Discord. Nous monetizes via a cloud-hosted version at $20-$200 a month. In July 2026, TechCrunch reported the company was finalizing a round of at least $75 million led by Robot Ventures, with USV participating, at a $1.5 billion valuation.
How it ended up
Still operating and scaling; no exit. The $75M+ round was reported as finalizing in July 2026.
Background
Nous Research is an open-source AI lab founded in 2023 by Jeffrey Quesnelle, Karan Malhotra, Ryan Teknium and Shivani Mitra, best known for the Hermes agent and for open coding and math models. Hermes is a locally run AI agent that ships with built-in skills - web search, coding, image understanding - and is designed to learn from usage and add skills on its own. Users run it on a desktop or VPS, or pay $20-$200 a month for a cloud-hosted version, and interact with agents through Telegram and Discord.
The bet is that open source is a distribution advantage, not a weakness: give away the agent, then charge for convenience. Weeks after OpenClaw's locally run agent went viral, Nous shipped Hermes as a fast-following competitor with a differentiating feature set, and the agent amassed roughly 214,000 GitHub stars and nearly 40,000 forks.
Investors have backed the thesis aggressively. After a $50 million Series A led by Paradigm in April 2025 and about $70 million in total prior funding, TechCrunch reported in July 2026 that Nous was finalizing a round of at least $75 million led by Robot Ventures, with USV participating, at a $1.5 billion valuation - a sharp step up in less than 15 months. The new capital is earmarked for expanding Hermes' products and business model.
What has to be true
- OpenClaw's virality proved demand for local agents; Hermes shipped weeks later with a differentiating feature set and rode the same wave.
- About 214,000 GitHub stars and nearly 40,000 forks give Hermes developer traction no closed assistant can match.
- The business model separates distribution from revenue: the local agent is free, while cloud tiers at $20-$200 a month monetize convenience.
- Hermes compounds its lead by learning from usage and building skills automatically, reducing manual engineering.
- The valuation step from $1B (April 2025 token valuation) to $1.5B within about 15 months signals investor conviction in open-source AI.
What can be applied
Give away a locally run agent as distribution, charge for cloud convenience, and ship fast on the heels of a viral rival - open source becomes the moat, not the weakness.
Aftermath
As of 2 September 2026, Nous Research is operating as an open-source AI lab with Hermes as its flagship. The agent had roughly 214,000 GitHub stars and nearly 40,000 forks in July 2026, plus a cloud version at $20-$200 a month and Telegram/Discord integrations. A round of at least $75 million led by Robot Ventures with USV at a $1.5 billion valuation was reported finalizing in mid-July by TechCrunch and The Block; Nous had not publicly confirmed the close. The capital is earmarked for expanding Hermes' products and business model.
