Funding Alert: Nous Research Raises $90M Series B

Oct 9, 20261 min
TL;DRNous Research raised a $90M Series B at a $1.5B valuation, led by Robot Ventures with Nvidia and Samsung among the participants. The signal: an open-source agent framework's own replicability can become a business moat — the more it gets cloned, the stronger the ecosystem lock-in.

What the Company Does

Nous Research builds an open-source AI agent — its Hermes Agent is a free-to-use personal and enterprise agent that anyone can run on their own infrastructure for customized, multi-step workflows, without handing their data to a closed platform.

Hermes Agent has been cloned more than 24 million times and, by the company's own estimate, drives about 2.5% of global AI token usage, making it popular among individual developers. This round funds "Hermes for Businesses," extending the open-source agent — until now mostly aimed at developers and individuals — into the enterprise market, letting companies deploy customized agents for multi-step workflows while keeping their data private.

Per The Wall Street Journal, Nous Research's annualized revenue was about $36M as of mid-September, and the company expects to pass $100M by the end of 2026.

What This Round Signals

What It Means for the Agent Ecosystem

An open-source agent framework reaching a $1.5B valuation shows the market isn't only buying the story of closed agent platforms — open-source replicability itself can become a business moat. The more it gets cloned, the stronger the brand and ecosystem lock-in, which runs against the usual assumption that open source means no moat at all.

What Investors Are Betting On

Lead investor Robot Ventures focuses on early-stage crypto and AI infrastructure bets; the participant list includes Nvidia (hardware ecosystem ties), Samsung (potential device integration), and 1789 Capital, where Donald Trump Jr. is a partner. That mix suggests Nous Research isn't just a bet on the technology — it's also a bet on relationships with hardware makers and a newer political-capital network.

Numbers Worth Watching

  • From zero to a $1.5B valuation and $158M raised in three years
  • ARR is projected to nearly triple, from $36M in mid-September to $100M by year-end — in under four months
  • More than 24 million clones of the open-source release, driving about 2.5% of global AI token usage — a rare case where "open-source reach" gets turned into a hard number

Watchlist Status

Nous Research is not currently on the watchlist. Recommend adding it to section B2 (Agent Frameworks), alongside LangChain/LangGraph and CrewAI — tracking the enterprise rollout of Hermes for Businesses and its share of global token usage.

Today's Takeaway

The common assumption is that open-source projects are hard to monetize because anyone can take the code for free. Nous Research used "cloned 24 million times" as its valuation leverage to raise $90M, showing that once open-source usage is large enough to move global token-usage share, replication itself becomes the distribution channel — and monetization gets easier once users already have the habit, not harder.
