Launch HN: Momentic (YC W24) – Agents that catch bugs by using your app

Momentic (YC W24) offers an AI QA engineer that tests applications end-to-end, catching bugs before they ship. It allows users to verify critical flows and find bugs from a prompt, with reported metrics including 77,813 tests created, 70,607,819 test runs executed, and 117,010 bugs caught. Momentic aims to accelerate software development by integrating verification into the agent loop, enabling teams to ship faster and with greater confidence.

Unlike traditional QA, Momentic's agents actively use the app to catch bugs, integrating end-to-end testing directly into the development process for faster, more scalable verification.
