Aakash Mahalingam
Aakash Mahalingam is the cofounder and CEO of Canary (YC W26), a startup building an AI QA engineer that reads your source code to catch broken user flows before they hit production. Before Canary he built Windsurf's enterprise product and helped push its self-serve plan to roughly $20M ARR in six months. An ICPC APAC finalist with earlier stints at AWS and Morgan Stanley, he now works out of Mountain View on the problem of testing keeping pace with AI-accelerated coding.
Arga Labs
Arga Labs builds real-world sandboxes for AI agents and agent-facing software. Every time a team opens a pull request, Arga spins up a temporary staging environment that mirrors production, redeploying only the services that changed and routing everything else to prod. It runs code and agents against resettable API 'twins' of third-party services like Stripe, Slack, GitHub, and Gmail, so teams can surface edge cases, simulate failures, and test at scale without touching live data. A YC P26 company founded by Phillip Li and Akira Tong, Arga reached roughly $40K in monthly recurring revenue within seven weeks of launch.
Canary
Canary is an AI QA engineer that reads your source code to understand developer intent, then automatically generates and runs end-to-end tests on every pull request. Instead of flaky DOM scraping or screenshot analysis, it reads the diff, works out what a change is meant to do, and tests the real user flows it touches - catching broken checkout, auth, and billing before code reaches production. Founded in 2026 by ex-Windsurf, Cognition, and Google engineers, the two-person San Francisco team is part of Y Combinator's Winter 2026 batch.
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. A software engineer who worked in Japan, Singapore, and the US, he kept running into the same problem everywhere: testing software takes too long.
