Nous Research Secures $90 Million Series B Funding at $1.5 Billion Valuation
Nous Research, the startup behind the popular open source Hermes Agent, has successfully raised $90 million in a Series B funding round, bringing its valuation to an impressive $1.5 billion. This milestone confirms earlier reports by TechCrunch, highlighting the company’s rapid growth and increasing influence in the AI space.
Founded just three years ago, Nous Research has quickly established itself as a key player in the development of AI-driven assistants. The round was led by Robot Ventures, with notable participation from heavyweight investors including Nvidia, Union Square Ventures, Menlo Ventures, Samsung, and 1789 Capital—a firm where Donald Trump Jr. holds a partnership. With this latest influx of capital, Nous Research has now raised a total of $158 million.
Widespread Adoption and Developer Popularity
The Hermes Agent, which is open source, has gained remarkable traction among developers and individual users alike. According to Nous Research’s internal estimates, the software has been cloned more than 24 million times. This extensive adoption translates to roughly 2.5% of global AI token usage being driven by Hermes Agent, underscoring its significance in the broader AI ecosystem.
Such widespread use speaks to the robustness and versatility of the Hermes Agent, which allows users to create customizable AI assistants capable of executing complex, multi-step workflows. The open source nature of the project has fostered a strong community, contributing to its continuous improvement and innovation.
Expanding into the Enterprise Market
With the new funding, Nous Research is pivoting toward the enterprise sector through its initiative, “Hermes for Businesses.” This offering enables companies to deploy tailored AI agents that manage sophisticated workflows while ensuring data privacy and security—two critical concerns for organizations adopting AI technologies.
By focusing on enterprise clients, Nous Research aims to capitalize on the growing demand for AI solutions that integrate seamlessly with existing business processes. The ability to maintain data confidentiality while automating tasks positions Hermes as a competitive tool in the enterprise AI landscape.
Strong Financial Trajectory
Financially, the company is on a steep growth trajectory. By mid-September 2026, Nous Research had reached approximately $36 million in annualized revenue. According to a report by The Wall Street Journal, the startup expects to surpass $100 million in revenue before the end of 2026, highlighting strong market demand and effective monetization strategies.
This rapid revenue growth, combined with significant investor confidence, reflects Nous Research’s expertise and authority in the AI assistant market. Their commitment to open source principles, coupled with enterprise-grade solutions, offers a compelling value proposition that balances innovation, transparency, and security.
