The Funding Round
Nous Research announced on October 7, 2026 that it had closed a $90M Series B funding round. The round was led by Robot Ventures, with participation from Nvidia, Microsoft's M12 investment fund, Samsung, Union Square Ventures, Menlo Ventures, and 1789 Capital. According to the announcement, the new round puts the startup's valuation at $1.5B, with total funding raised reaching $158M. The Wall Street Journal broke the news first, followed by TechCrunch with the details.
The names on the investor list are noteworthy: Nvidia and Microsoft's M12 fund are active in the artificial intelligence (AI) infrastructure market, while Samsung is strong in the device and semiconductor ecosystem. Participation by classic venture firms such as Union Square Ventures and Menlo Ventures signals growing institutional interest in open-source AI projects. A $1.5B valuation makes the company a "unicorn" — one of the largest valuations in the open-source AI agent space.
The capital is aimed at a single goal: turning the Hermes agent into a ready-made product for enterprise customers. The company has built a large audience in the open-source community — now it's time for paying business customers. A Series B typically comes after a product has found market fit, with investors betting on accelerating growth. For Nous Research, the proof of adoption is 22.7 million downloads and growing revenue.
The Road to the Enterprise Market
Nous Research will spend the new capital on expanding its "Hermes for Businesses" initiative. Enterprises will be able to run customized AI agents for multi-step workflows on their own infrastructure, with data guaranteed to remain private and secure.

The enterprise segment is the traditional monetization path for open-source AI companies: a freely distributed tool wins over developers, then a business version is sold with security, support, and integration services. Data privacy is decisive for banks, healthcare, and large enterprises — they require agents to run inside internal systems. Nous Research is offering a model tailored to exactly that demand.
The "for Businesses" phrase in the initiative's name draws a clear line between open Hermes and the paid enterprise version: the base agent stays open, while business features ship as a separate package. The name formalizes the company's two-track strategy: the open-source community develops the product, and the business version generates revenue.
The Open-Source Agent's Success
Nous Research's open-source Hermes AI agent has been cloned more than 24 million times and downloaded 22.7 million times since February (per OpenRouter data). By usage volume, Hermes has pulled ahead of rival OpenClaw. These figures were the company's main weapon in raising capital: investors see a finished, widely used product.
The open-source AI agent market is fiercely competitive in 2026. Hermes stands out because independent developers can easily plug it into their projects, and the agent handles multi-step tasks with relative reliability. Clones and downloads don't translate directly into revenue, but they show ecosystem strength: the more developers know the tool, the more companies will consider its business version.
Overtaking OpenClaw is symbolic — the race for leadership in this space is wide open, and Nous Research is in front for now.
Financial Results
According to the Wall Street Journal, the company's annualized revenue reached $36M in mid-September 2026. The company plans to cross $100M in annualized revenue by the end of 2026. If those plans materialize, Nous Research will become one of the fastest-growing startups in the open-source AI space.
The path from $36M to $100M means nearly tripling in three months — a pace that signals fast-signing enterprise contracts. The newly raised $90M will fund that growth: expanding the sales team, strengthening enterprise infrastructure, and earning security certifications.
Revenue momentum is the decisive metric for investors: the plan to go from a $36M annual run rate to $100M shows the company is betting on its pipeline of enterprise contracts. The newly raised $90M will be spent on exactly the infrastructure needed to close those deals — sales, security certifications, and customer support.
No conclusion, just the facts: a $1.5B valuation, $158M in total funding, and 22.7 million downloads — Nous Research has become one of the most talked-about open-source AI startups of 2026.
