What hud does

HUD (YC W25) is developing agentic evals and RL environments for Computer Use Agents (CUAs) that browse the web for frontier AI labs. Our CUA Evals framework is the first comprehensive evaluation tool for CUAs. People don't actually know if AI agents are working reliably. To make AI agents work in the real world, we need detailed evals for a huge range of tasks. We're backed by Y Combinator, and work closely with frontier AI labs to provide agent evaluation and training infrastructure at scale.

Platform for building RL environments and evals

What is your company going to make? Please describe your product and what it does or will do.

We build agentic evals and reinforcement learning environments tailored to testing and training Computer Use Agents that browse the web. Our CUA Evals framework helps AI labs rigorously evaluate agent reliability on a wide range of web-based tasks, which no one else is doing at scale.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and would keep the company based here after YC.

Explain your decision regarding location.

San Francisco is where most frontier AI labs are, and being here keeps us close to our users and collaborators who shape our product.

Is this the real hud YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from hud's public data (launch notes, founder backgrounds, product description). It shows how a company like hud would present itself to YC, not the text they submitted.
