AppPerfect Corp
For more than two decades, AppPerfect has worked the unglamorous seam between a software demo and a dependable production system. Its bet is simple: test the failure, watch the machinery, and fix the bottleneck before users find it first.
Docket
Docket is a San Francisco AI QA testing platform that lets teams write end-to-end tests in plain English and keeps them running as the app changes. Instead of brittle CSS selectors, its multimodal agents look at the screen and click where a human would, recording pixel coordinates and self-healing when the UI shifts. Founded in 2025 by ex-Stripe and ex-Citadel engineers Nishant Hooda and Boris Skurikhin, Docket went through Y Combinator's Spring 2025 batch and covers web, mobile, and desktop apps.
Katalon
Katalon is an Atlanta-based software company that builds an AI-augmented, all-in-one quality management platform for software testing. Its flagship products - Katalon Studio, TestOps, TestCloud, and the newer TrueTest - let QA and DevOps teams create, run, and analyze automated tests across web, mobile, API, and desktop applications with both low-code and full-code approaches. Spun out of KMS Technology, Katalon is used by more than 30,000 teams across 80+ countries and has repeatedly been named a G2 Leader in software testing.
Autosana AI
Autosana AI is the first agentic QA platform for iOS, Android, and Web. Founded by Yuvan Sundrani and Jason Steinberg in June 2025 and backed by Y Combinator (S25 batch), Autosana replaces brittle test scripts with AI agents that navigate apps like real users, described in plain English. The company raised $3.2M in February 2026 from YC, Pioneer Fund, Phosphor Capital, DeVC, 468 Capital, and angels including Paul Graham. Revenue is growing 100%+ month over month, and the platform now protects apps serving over 100 million daily active users. The name comes from the Latin 'autosana' — to heal oneself — reflecting tests that evolve alongside the product rather than breaking on every UI change.
