TesterArmy is a YCombinator backed San Francisco- and Warsaw-based startup that provides AI-powered software testing agents. The company, founded in 2026, aims to replace manual test scripting with autonomous AI agents that verify user journeys across web and mobile applications using plain language instructions.
The company has just raised $1.2M in pre-seed funding. The round includes Script Capital, Eight Capital, AIP Seed, and angel investors including Guillermo Rauch (Vercel), Charlie Cheever (Expo), Walden Yan (Cognition), Theo Browne (T3), Zeno Rocha (Resend), and many more.
TesterArmy claims to be a testing automation software that’s built from the ground up around AI agents. On every change in the application, AI agents clicks through the product like real users. All you need to test your app is a URL, then the tool claims to handle authentication, bot detection, agent orchestration and more. This helps teams focus on what’s important – building the product. Everything is published under the MIT license: tools for running QA with coding agents, testing APIs and reading agent traces, etc.
