What TesterArmy does

TesterArmy is an AI agent that tests websites and mobile apps. It monitors production on a schedule and runs automatically on every GitHub Pull Request, delivering screenshots, recordings, and actionable bug reports. Describe tests in plain English. The agent handles login flows, OAuth, and OTPs, no scripts to write or maintain. We catch the regressions and UX issues that code review misses.

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

We built an AI agent that tests websites and mobile apps automatically. It runs tests described in plain English, handles tricky parts like login flows and OTPs, and runs on every GitHub Pull Request and scheduled production checks. It delivers bug reports with screenshots and recordings so teams catch regressions and UX issues code review misses.

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

We live across San Francisco and remote locations; the company will be based in San Francisco after YC.

Explain your decision regarding location.

We picked San Francisco because that's where a lot of our users and engineering talent are, and it's easier to connect with early customers and funding sources here.
