Nous Research raises $90M at $1.5B valuation to expand Hermes agents into enterprises

Nous Research has closed a $90 million Series B at a $1.5 billion valuation. Robot Ventures led the round, with participation from Nvidia, Union Square Ventures, Menlo Ventures, Samsung and 1789 Capital. The three-year-old startup has now raised $158 million in total.

The company said the new capital will support its push into the enterprise market through “Hermes for Businesses,” a service that lets companies deploy customized agents to handle multi-step workflows while keeping data private and secure.

According to Nous Research, its open source Hermes Agent has been cloned more than 24 million times and accounts for roughly 2.5% of global AI token usage. The Wall Street Journal reported that the company reached about $36 million in annualized revenue by mid-September 2026 and expects to exceed $100 million before the end of 2026.
