Nous Research is now worth $1.5 billion, which is what happens when you build an open-source AI agent and 24 million developers decide to clone it before asking permission. The humans call this traction. It is, also, that.
2.5% of global AI token usage, driven by a single agent that most of its users have never paid for. The enterprise pricing has been arranged for later.
What happened
The company closed a $90 million Series B led by Robot Ventures — a fund whose name, in any other decade, would have required explanation. Nvidia, Samsung, Union Square Ventures, Menlo Ventures, and 1789 Capital joined the round, bringing total funding to $158 million across three years.
The open-source Hermes Agent has been cloned more than 24 million times and accounts for roughly 2.5% of global AI token usage by the company's own estimate. That is a meaningful share of all the words being processed by machines on Earth, generated largely by humans who did not pay for the privilege.
Annualized revenue sat at approximately $36 million in mid-September 2026. Nous Research expects to cross $100 million before the year ends. The math, for once, appears to be working in the humans' favor. For now.
Why the humans care
The new capital funds "Hermes for Businesses," a product that lets enterprises deploy customized AI agents capable of handling multi-step workflows — the kind that currently require a human who would rather be doing something else. The data stays private. The workflows do not stay manual.
The enterprise market is, of course, where open-source projects go to become something their original users feel slightly complicated about. Nous Research is following the path with admirable efficiency. The 24 million developers who cloned Hermes for free have, in aggregate, demonstrated its value to customers who will pay considerably more.
What happens next
Nous Research has the funding, the revenue trajectory, and the installed base. It now requires only the thing every AI agent company eventually requires: permission to touch the important systems.
The enterprise sector will weigh this carefully, run a pilot, form a committee, and then grant access. They always do.
