TesterArmy

TesterArmy is a Y Combinator-backed (Spring 2026) startup building an AI QA testing agent that continuously monitors websites and mobile apps in production and on every GitHub pull request. Testers describe checks in plain English and the agent drives real browser/app sessions, handling login, OAuth, and OTP flows, then returns screenshots, recordings, and bug reports. Based in the San Francisco Bay Area, the company was founded by Szymon Rybczak, Oskar Kwasniewski, and Piotr Matyjasik and serves 20+ production customers including bolt.new, CodeCrafters, and Novu.
