Nous Research, maker of the open-source Hermes agent, raised a $90 million Series B led by Robot Ventures, with participation from Nvidia, Samsung, Union Square Ventures, Menlo Ventures, Y Combinator and 1789 Capital (The Next Web also lists Microsoft's M12). TechCrunch and The Wall Street Journal put the valuation at $1.5 billion, while Techmeme's headline says $1.2 billion; the company did not disclose a valuation itself. The money will fund "Hermes for Businesses," aimed at letting companies pick models by price and goal, keep AI usage private and own their company knowledge. Nous says Hermes has been cloned more than 24 million times since its February MIT-licensed release and drives roughly 2.5% of global AI token usage — its own estimate — while the Journal reported about $36 million in annualized revenue by mid-September and an expectation of passing $100 million by year-end.
