Nous Research, the developer of the open-source Hermes agent, has confirmed a $90 million Series B raise at a $1.5 billion valuation, bringing its total funding to $158 million.
The round was led by Robot Ventures with participation from Nvidia, Samsung, Union Square Ventures, and others. The capital will fund the launch of "Hermes for Businesses," allowing companies to deploy customized AI agents for multi-step workflows while keeping data private.
According to TechCrunch, the open-source Hermes agent has been cloned over 24 million times, driving roughly 2.5% of global AI token usage (a company estimate). The WSJ previously reported that Nous had approximately $36 million in annualized revenue by mid-September 2026 and expects to pass $100 million before the end of the year.
