Nous Research Hits $1.5 Billion Valuation with $90 Million Series B to Scale Open-Source AI for Enterprise

Nous Research, the rapidly ascending startup behind the widely adopted Hermes Agent, has officially secured $90 million in a Series B funding round, pushing the company’s valuation to a notable $1.5 billion. The announcement, which confirms earlier reporting regarding the startup’s fundraising trajectory, underscores the growing influence of open-source artificial intelligence in a market increasingly dominated by proprietary, closed-model giants.

The funding round was led by Robot Ventures, with a robust roster of high-profile participants. Key investors include Nvidia—a linchpin in the current AI hardware ecosystem—as well as Union Square Ventures, Menlo Ventures, and Samsung. Notably, 1789 Capital, the firm where Donald Trump Jr. serves as a partner, also participated in the round. This latest injection of capital brings the total funding raised by the three-year-old startup to approximately $158 million, cementing its status as a significant player in the competitive AI development landscape.

A Force in Open-Source AI

Since its inception, Nous Research has carved out a unique niche by prioritizing the open-source community. The Hermes Agent, the company’s flagship offering, has become a staple for developers and individual users alike. According to internal estimates provided by the startup, the model has been cloned more than 24 million times, a staggering figure that highlights the reach of the platform. More impressively, the company estimates that its models are currently responsible for approximately 2.5% of global AI token usage—a metric that serves as a testament to the utility and popularity of their technology among power users and independent developers.

This high level of adoption has placed Nous Research in a favorable position as the industry shifts its focus toward more specialized, efficient, and transparent AI architectures. By providing a viable, high-performing open-source alternative to the proprietary models offered by big-tech incumbents, Nous has managed to foster a loyal ecosystem that relies on its tools for a wide array of applications.

Transitioning to Enterprise Solutions

With the infusion of $90 million in new capital, Nous Research is preparing to shift its strategic focus toward the enterprise sector. The company intends to launch a dedicated service offering, "Hermes for Businesses," designed to address the specific needs of large-scale organizations that require more than just a general-purpose assistant.

The core value proposition for this enterprise push centers on customization and data sovereignty. While many organizations are hesitant to integrate third-party AI models due to concerns regarding data privacy and the security of proprietary information, Nous Research aims to provide a solution that allows businesses to deploy customized AI agents. These agents are designed to manage complex, multi-step workflows—tasks that require deeper reasoning and integration than the simpler chatbots currently in use. By offering an enterprise-grade version of its technology, Nous hopes to capture a share of the burgeoning corporate AI market, where security and reliability are paramount.

Rapid Financial Growth

The financial performance of Nous Research reflects the broader boom in the AI sector. By mid-September 2026, the company reported an annualized revenue run rate of approximately $36 million. Even more ambitious is the company’s internal projection: Nous Research expects to cross the $100 million threshold in annualized revenue before the conclusion of 2026. This aggressive growth trajectory, as first reported by The Wall Street Journal, illustrates how quickly the startup has moved from an open-source darling to a commercially viable enterprise software provider.

The rapid scaling of revenue is a clear indicator that the market is ready for more flexible AI infrastructure. As companies move beyond the initial "experimentation phase" of generative AI, they are seeking tools that offer greater control over their underlying models. Nous Research’s business model, which bridges the gap between community-driven open-source innovation and corporate-ready software, appears to be hitting the market at a critical juncture.

Navigating a Competitive Landscape

The involvement of strategic investors such as Nvidia and Samsung suggests that industry heavyweights are betting on the long-term viability of the open-source approach to AI development. For Nvidia, the partnership is likely an investment in a software ecosystem that drives demand for their high-performance computing hardware. For Samsung, the collaboration may signal an interest in integrating sophisticated, localized AI agents into a broader range of consumer and industrial hardware.

The inclusion of 1789 Capital and other venture firms highlights the diverse interests currently converging on the AI sector. As Nous Research scales, it will face the challenge of maintaining its open-source roots while satisfying the stringent demands of enterprise clients. The company’s success will likely hinge on its ability to prove that its "Hermes for Businesses" suite can provide the same level of performance and developer flexibility that fueled its initial rise, while also delivering the security, uptime, and integration support that enterprise CIOs demand.

As the company enters this new phase of maturity, the pressure to deliver on its revenue projections will intensify. However, with a $1.5 billion valuation and a significant war chest of capital, Nous Research has the resources necessary to invest in the talent and infrastructure required to compete with larger, more established incumbents.

For the developer community that has championed Hermes over the last three years, the transition to an enterprise-focused company will be watched closely. Whether Nous Research can successfully balance its community-driven heritage with the demands of its corporate board and enterprise customers remains the defining question for the company’s next chapter. For now, the startup remains one of the most compelling examples of how an open-source project can evolve into a major commercial entity, fundamentally altering the way businesses interact with and deploy artificial intelligence.
