Agent Infrastructure Startup Nous Research Valued at $1.5B in New Round, 50% Jump in Under Three Months

Nous Research is in talks to raise at least $75 million at a $1.5 billion valuation, led by Robot Ventures with USV participating, per TechCrunch sourcing on 13 July 2026. The round closes less than three months after a $50 million Series A at $1 billion valuation. The pace reflects capital chasing open-source agent frameworks with proven adoption—Hermes, Nous's core project, has 214,000 GitHub stars—but lacks disclosed product milestones to underwrite the 50 percent step-up.
