Describe what your company does in 50 characters or less.

Hands off QA via intelligent browser agents.

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

We build autonomous browser agents that simulate real user behavior and run continuous quality assurance tests automatically. Our product runs swarms of these agents across your site or app to find bugs without manual scripts or ongoing input.

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

We live and work in New York City, and after YC we plan to keep Propolis based here.

Explain your decision regarding location.

We're based in New York because that's where we live and work. The product is digital and remote, so the location is convenient for us without limiting reach or efficiency.

Frequently Asked Questions

Is this the real Propolis YC application?

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