Nous Research Raises $90M, Takes Hermes Agents Enterprise

Nous Research has raised a $90 million Series B at a $1.5 billion valuation, and the open-source AI startup is using the new capital to take its Hermes agents from developer favorite to enterprise product. The round was led by Robot Ventures, with participation from Nvidia, Union Square Ventures, Menlo Ventures, Samsung, and 1789 Capital, bringing the three-year-old company's total funding to $158 million, according to reporting by TechCrunch.

At the center of the announcement is "Hermes for Businesses," a new enterprise offering that lets companies deploy customized Hermes agents to handle multi-step workflows while keeping their data private and secure. The move puts Nous Research squarely into the fast-growing enterprise agent market, where demand for agentic automation has been surging through 2026.

The numbers behind the raise are striking. The open-source Hermes agent has been cloned more than 24 million times and drives roughly 2.5% of global AI token usage, according to the startup's estimates. On the revenue side, Nous was at roughly $36 million in annualized revenue by mid-September 2026 and expects to pass $100 million before the end of the year, The Wall Street Journal reported. For a company built on open-source distribution, that trajectory suggests the enterprise tier could convert community momentum into durable revenue.

Why the open-source agent bet is paying off

Nous Research's rise reflects a broader shift in how AI agents reach users. While proprietary labs have spent billions building general-purpose agents behind APIs, Hermes agents have grown through grassroots adoption: developers download, fork, and fine-tune them for their own tasks, and that community compounds into distribution no marketing budget can buy. According to the company, its open-source footprint is now large enough to account for about one in every forty AI tokens generated worldwide.

That footprint — built entirely on Hermes agents in the wild — is also what attracted a notable investor mix. Nvidia's participation signals confidence in the infrastructure layer underneath agent workloads, while Union Square Ventures and Menlo Ventures bring consumer-scale product experience. The round was led by Robot Ventures, a firm with deep roots in crypto and robotics communities that overlap heavily with the open-source AI crowd. More details on the company's direction can be found in Nous Research's own announcements.

The timing matters too. Agent adoption data from late 2026 paints a picture of agents moving from demos to daily work: developer surveys show a large majority now use coding agents weekly, and enterprises are asking which agent platforms they can run inside their own walls. An open-source agent that companies can customize and run privately has an answer ready for both groups.

Hermes for Businesses and the enterprise agent race

The enterprise launch is the real test. "Hermes for Businesses" promises customized Hermes agents that take on multi-step workflows without sending sensitive company data through third-party clouds — a direct answer to the privacy objections that have slowed agent adoption inside regulated industries like finance, healthcare, and legal services.

Competition is intense. Established vendors are racing to put agents into enterprise workflows, from customer-service platforms to finance software, and several startups have raised large rounds this month alone to build agent infrastructure for specific verticals. According to coverage in the AI Agents News Brief for October 7, the same week saw Series B rounds for order-to-cash agents and creative-work agents, plus a $22 billion valuation event for voice-agent maker ElevenLabs.

What distinguishes Nous Research is that it arrives with a pre-installed developer community of tens of millions of clones. Enterprise software history suggests that bottom-up adoption — the tools engineers already use on the side — often wins the budget fight over top-down sales. If Hermes for Businesses can convert even a fraction of the millions of developers already running Hermes agents into paying enterprise deployments, the $100 million revenue target for year-end 2026 starts to look conservative.

What to watch next

The valuation math will be under scrutiny. At $1.5 billion against $36 million of annualized revenue, investors are paying roughly 40 times forward-ish revenue for growth — a multiple that demands the enterprise product land quickly. The company's bet is that the open-source agent flywheel makes that growth cheaper than the incumbent playbook of enterprise sales teams and professional services.

For the agent ecosystem, the raise is another datapoint in an unmistakable trend: open-source agents are no longer a research curiosity. They are a product category with enterprise ambitions, venture-scale funding, and — in the case of Hermes agents — a claim on a measurable share of global AI compute. Hermes agents helped prove the model; Hermes for Businesses will have to prove the business.
