Nous Research $1.5B Valuation: $90M Series B for Hermes Agents

What happened

Nous Research, the company behind the open source Hermes Agent, has confirmed a $90 million Series B round that values it at $1.5 billion.12 Alongside the funding, the company is moving to offer its AI agents to business users, extending a project known in open source circles into the enterprise market.12

Robot Ventures led the round.2 Nvidia, Union Square Ventures, Menlo Ventures, Samsung and 1789 Capital also participated.2 1789 Capital counts Donald Trump Jr. among its partners.2 The new money brings Nous Research's total funding to $158 million, a notable sum for a company that is about three years old.2

The announcement also confirms what TechCrunch had reported earlier about the round and the valuation.2 Both outlets agree on the core figures: $90 million raised and a $1.5 billion valuation.12 TechCrunch framed the news around the confirmation of the valuation and the enterprise launch.1 The AI Insider gave more detail on who invested and how much the company has raised overall.2

Why the investor list matters

The mix of backers says something about how the company is positioned.

• Nvidia has invested across much of the AI startup ecosystem. Its presence suggests Nous Research is seen as part of the broader demand for AI compute and tooling.2
• Samsung adds a large hardware and consumer electronics company to the cap table.2
• Union Square Ventures and Menlo Ventures are established venture firms. Their participation gives the round traditional institutional credibility.2
• 1789 Capital brings a politically connected name into the deal, through Donald Trump Jr.'s role as a partner.2

This is my interpretation, not something the company has stated. A cap table this varied suggests investors want exposure to agent-based AI from several directions: infrastructure, devices and enterprise software. The 1789 Capital link stands out because AI policy in the United States has become heavily politicized. Whether that connection affects the company's direction is not clear from the available reporting.

From open source project to enterprise vendor

The most important strategic change is the move toward business customers. Nous Research built its reputation on Hermes Agent, which is open source.2 Turning open source credibility into commercial revenue is a familiar path in software. It is also a hard one.

Open source projects can attract developers and goodwill quickly. Enterprises, however, usually want things that a free project alone does not provide:

• support commitments
• security assurances
• integration with existing systems
• someone accountable when things break

Launching agents aimed at business users suggests Nous Research plans to build that commercial layer on top of its open source base.12 The reporting does not explain in detail how the enterprise offering will differ from the open source version, or how it will be priced. Those details will matter a great deal for whether the $1.5 billion valuation holds up.

Reading the valuation

A $1.5 billion valuation on $158 million in total funding implies investors expect substantial growth.2 For a three-year-old company, a valuation like that rests on expectations about the future more than on current revenue. The available reporting does not disclose revenue.

Several factors likely support the price, though this is analysis rather than confirmed reasoning from investors:

• Agent hype. AI agents, meaning systems that can take actions and complete multi-step tasks, are a major focus for AI investment right now.
• Open source traction. An open source product with an established user base gives a startup a distribution advantage over closed competitors starting from zero.
• Strategic backers. Investors such as Nvidia and Samsung could offer partnerships or channels that a typical startup would struggle to access.2

The risks are just as real. The enterprise agent market is getting crowded, and large AI labs and incumbent software vendors are pursuing the same customers. Nous Research will need to show that an open source-first approach gives businesses something they cannot easily get elsewhere. Possible advantages include transparency, customization, or less dependence on a single proprietary provider.

The bottom line

The confirmed facts are clear. Nous Research raised $90 million, is valued at $1.5 billion, has raised $158 million in total, and is now selling Hermes-based agents to businesses.12

My reading is that this round marks Nous Research's shift from a respected open source player to a company that must prove it can run an enterprise business. The investor roster gives it resources and connections. The open source foundation gives it a community. What remains unproven is the commercial step: whether businesses will pay for Hermes agents at a scale that justifies a unicorn valuation. The next year of customer adoption will say more than this funding announcement can.
