mabl and the art of believing a red light
Software teams can automate thousands of checks and still distrust the result. mabl sells a way to make testing easier - and its own engineers offer a useful lesson in knowing when to stop.
ACCELQ’s first sale was $300. The real prize was less test repair.
Software changes. Tests break. ACCELQ built its business around making that expensive little ritual less inevitable - and letting the people who understand the work help automate it.
Sauce Labs and the Art of Renting Time
A test can click a button. A testing company must make that click mean something across browsers, phones, and release deadlines. Sauce Labs built its business in the gap.
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.

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.

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.
