Autosana is an AI-powered end-to-end testing platform for mobile and web applications, providing AI agents that create, update, and execute tests across iOS, Android, and web. Its vision-based approach tests applications the way humans would, eliminating manual testing and brittle test-script maintenance, and serves as the testing layer for coding agents. The platform powers QA for apps serving 100M+ daily active users and has grown revenue by over 100% each month on average since launching in June 2025. Founded in 2025 by Yuvan Sundrani and Jason Steinberg, Autosana was part of YC's Summer 2025 batch.
