Hermes' maker is raising again just three months after its Series A

Signals Inbox·July 14, 2026·AI Agents

Nous Research is reportedly raising at least $75 million at a $1.5 billion valuation, only three months after closing a $50 million Series A. The striking part is not just the money. It is the speed: investors may be marking the company up by roughly 50% in one quarter as its open-source Hermes agent explodes across GitHub.

Q1What actually happened?

TechCrunch reports that Nous Research, the company behind Hermes Agent, is trying to raise at least $75 million at a $1.5 billion valuation. The financing is not closed yet. It comes only about three months after Nous reportedly raised a $50 million Series A at a valuation near $1 billion.

Q2Why is the timing so unusual?

Because startups normally use a major round for much longer before returning to investors. Nous appears to be raising again almost immediately. The proposed round is also at least 50% larger than its previous one, while the valuation has reportedly climbed about 50% in a single quarter. That looks less like normal fundraising and more like investors rushing to price sudden momentum.

Q3What is Hermes Agent?

Hermes is an open-source AI agent that can use tools, remember information, create reusable skills, run scheduled tasks, and connect to services like messaging apps. Unlike a normal chatbot, it is designed to keep working through a task and improve from past experience. It can run through a desktop app, terminal, or web dashboard on macOS, Windows, and Linux.

Q4What changed in the last few months?

Developer adoption moved extremely fast. Hermes now has roughly 214,000 GitHub stars and almost 40,000 forks. Its July release involved more than 370 community contributors, about 1,000 merged pull requests, and over 1,700 commits since the previous major version. GitHub stars do not equal paying customers, but that scale makes Hermes one of the most visible open-source agent projects.

Q5Why would investors value an open-source tool this highly?

Open source can become distribution. Developers test the software, improve it, create integrations, and bring it into companies without waiting for a sales team. Nous could eventually make money through hosted services, enterprise support, premium infrastructure, model access, or tools built around Hermes. Investors are betting that a large developer community can become a commercial platform.

Q6How does this compare with other AI agents?

Closed products like Claude Code, Codex, Cursor, and enterprise agents usually control both the software and the customer relationship. Hermes takes the opposite route: anyone can inspect it, modify it, and run it with different models. That can spread faster and reduce vendor lock-in, but it also makes monetization harder because users do not necessarily need to pay Nous.

Q7So what is the real tension?

Hermes has already proved it can attract developers. It has not publicly proved that this attention supports a $1.5 billion business. The new funding would give Nous more power to hire, train models, and build infrastructure, but it also raises expectations very quickly. The next test is not more GitHub stars. It is whether open-source agent adoption turns into durable revenue before the valuation outruns the company.
