Nous Research, the open-source AI startup behind the Hermes agent platform, is closing in on a staggering $1.5 billion valuation in its latest funding round. The company is raising at least $75 million in a deal led by Robot Ventures with major participation from Union Square Ventures (USV), according to sources familiar with the matter.
The Round That Turned Heads
Founded in 2023 by Jeffrey Quesnelle, Karan Malhotra, Ryan Teknium, and Shivani Mitra, Nous Research has quickly become one of the most talked-about names in the AI agent space. Before this round, the startup had raised $70 million from investors including Paradigm, Robot Ventures, North Island Ventures, OSS Capital, and Balaji Srinivasan. The new funding catapults its valuation more than tenfold in under two years.
The deal reportedly drew enormous interest from investors, reflecting the market's voracious appetite for AI agent infrastructure. Neither Nous Research nor its lead investors commented publicly on the raise.
Why Hermes Stands Out
Hermes is an open-source AI agent that runs on a user’s desktop or a virtual private server, performing tasks autonomously around the clock. Unlike many agents that require manual prompt engineering for every new task, Hermes ships with built-in skills — web search, code execution, image understanding — and learns from usage to build new capabilities without manual intervention.
Key features that set Hermes apart from the crowded agent landscape:
- Built-in skill system: Users don’t write prompts from scratch; Hermes comes pre-loaded with proven tool-use patterns for search, coding, terminal control, and more.
- Auto-learning: The agent automatically refines its behavior based on how you use it, growing more effective over time without you lifting a finger.
- Multi-platform delivery: Users can chat with their agent, receive proactive messages, and delegate tasks across Telegram, Discord, and soon, more platforms.
- Cloud-hosted tier: For those who don’t want to self-host, Nous offers a managed cloud version from $20–$200 per month.
The Open-Source Advantage
Hermes has amassed roughly 214,000 stars and nearly 40,000 forks on GitHub, making it one of the most popular open-source AI projects in existence. The project’s rapid adoption has been fueled by developers who want transparency, control, and the ability to customize their AI agents without vendor lock-in.
This open-source DNA gives Nous Research a distribution advantage that proprietary AI startups struggle to match. Every developer who forks Hermes becomes a potential advocate — and a potential paying customer for the cloud tier.
More Than Just an Agent
While Hermes is the flagship product, Nous Research has also released specialized language models focused on coding and mathematics. These models power much of the agent’s reasoning and tool-use capabilities, and they’re available separately for developers to integrate into their own projects.
The company’s dual strategy — open-source community building plus a monetized cloud layer — mirrors the playbook that turned companies like Hugging Face and MongoDB into platform giants.
What’s Next?
Sources indicate the fresh capital will be used to expand Hermes’ product capabilities and scale the business model. As AI agents transition from experimental toys to workplace necessities, Nous Research is betting that the open-source, user-sovereign approach will win the enterprise.
With a $1.5 billion valuation and a GitHub community that rivals many billion-dollar developer tools, Nous Research is making a loud statement: the future of AI agents isn’t locked behind a paywall — it’s open, learnable, and running 24/7 on your own machine.
