TesterArmy
TesterArmy is a Y Combinator-backed (P26) startup building AI agents that test web and mobile apps the way a human would. Teams describe tests in plain English; the agent launches a real browser or device, clicks and types through user flows, handles logins, OAuth and OTP, then returns screenshots, recordings and actionable bug reports. It runs on every GitHub pull request and on a schedule against production, aiming to catch broken flows before customers do.
Ryo Chikazawa
Ryo Chikazawa is the co-founder and CEO of Autify, an AI-powered software testing automation company based in San Francisco and Tokyo.

Gal Vered
Gal Vered is the co-founder and CEO of Checksum.ai, a San Francisco startup that uses AI to automatically generate, run, and self-heal end-to-end software tests in Playwright and Cypress. A former Google product manager, Y Combinator-backed CTO, Kellogg MBA, and Israeli Navy officer, Vered is betting that as AI writes more of the world's code, the scarce and valuable skill becomes verification - proving the software actually works. Checksum sells testing as a result rather than a tool, generating 100-150 tests in a customer's first week and keeping them green as the product changes.
Yunhao Jiao
Yunhao Jiao is the co-founder and CEO of TestSprite, a Seattle startup building an autonomous AI testing agent that aims to be the verification layer for AI-generated code. A competitive programmer turned AWS engineer, he left a five-year run at Amazon after a single production regression on an on-call shift convinced him that verification, not generation, had become software's weakest link. Since founding TestSprite in 2023 with Shawnie Shan and Rui Li, he has grown it to roughly 100,000 developers and raised about $8.1 million across pre-seed and seed rounds, led most recently by Trilogy Equity Partners.
