What happened
Nous Research has raised a $90 million Series B, confirming a $1.5 billion valuation. TechCrunch reports the round was led by Robot Ventures, with participation from Nvidia and Union Square Ventures. The new capital brings the startup's total funding to $158 million.
The funding will support the launch of "Hermes for Businesses," an enterprise version of their popular open-source Hermes Agent. This new offering allows companies to deploy custom AI agents for multi-step workflows while keeping their data private and secure.
How the room's reading it
The $1.5 billion valuation is turning heads. Investors clearly see a massive opportunity in autonomous agents for the enterprise — a space many thought was still too early for this level of funding. The consensus among VCs on X is that this signals a shift from foundational models to valuable applications built on top of them.
Developers are pointing to the success of the open-source Hermes Agent as the real story. Its massive adoption, with over 24 million clones, created a strong foundation of trust and a ready-made talent pool. The move to a paid, private enterprise product is seen as a natural next step, validating the classic open-source-to-commercial playbook for a new generation of AI companies.
Sailfish's take
We've seen countless agent demos that look great but fall apart on real-world tasks. The valuation is impressive, but the real test for Nous is whether "Hermes for Businesses" can deliver reliability. Autonomy is useless if you can't trust the output for a multi-step financial report or a customer support sequence.
The money isn't the story — the potential for reliable, private workflow automation is. We're not jumping to build on it yet. We're watching to see the first case studies of businesses running complex, mission-critical workflows without constant human supervision. If they nail that, this changes the calculus for every enterprise building with AI.
