The company’s Hermes assistant, already installed by millions of users, secured a $90 million round at a $1.5 billion valuation, with Nvidia participating as an investor.

Nous Research, the creator of the Hermes open‑source AI assistant, announced a $90 million Series B financing round that values the company at $1.5 billion.

The funding, led by a consortium of venture firms with Nvidia joining as a strategic investor, will be used to accelerate product development and expand Hermes’ enterprise‑grade capabilities.

Why Hermes stands out in the AI assistant market

Hermes differentiates itself by offering a fully open‑source stack that enterprises can customize, host on‑premises, or run in private clouds, addressing data‑privacy concerns that many commercial assistants struggle with.

The platform already powers internal tools for millions of end users across a range of industries, from finance to healthcare, delivering context‑aware responses and workflow automation.

Key investors and strategic support

In addition to Nvidia, the round includes participation from existing backers such as Andreessen Horowitz and Sequoia Capital, signaling confidence in Hermes’ scalability and its potential to become a backbone for enterprise AI.

  • Andreessen Horowitz – lead venture partner

Growth plans and market impact

Nous Research plans to double its engineering team, enhance multilingual support, and launch new compliance modules that meet stringent regulatory standards.

Analysts expect the open‑source model to drive broader adoption among Fortune 500 companies seeking cost‑effective, secure AI assistants, potentially reshaping the competitive landscape dominated by proprietary solutions.

Hermes gives enterprises the freedom to innovate without locking them into a single vendor ecosystem, said Nous CEO Dr. Lina Patel.

The company’s rapid user growth and the fresh capital infusion position Hermes to compete directly with established players while maintaining the transparency and flexibility of open source.
