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.
Mobot
Mobot is a New York-based company that runs a fleet of real mechanical robots to test mobile apps on physical iOS and Android devices. Positioned as the first robot-powered QA-as-a-service platform, it uses computer vision and AI-guided robots - supervised by human QA experts - to automate the repetitive, human-like tests that emulators and software frameworks cannot reliably reproduce, such as push notifications, deep links, Bluetooth pairing, camera flows and multi-device interactions. Founded in 2018 by Eden Full Goh and launched publicly in 2022 with a $12.5M Series A, Mobot helps engineering and product teams cut manual testing hours, catch more bugs before app-store release, and ship faster.
Autify
Autify is an AI-powered software testing platform that lets engineering and QA teams create, run, and maintain automated tests without heavy scripting. Founded in 2016 by Ryo Chikazawa and Sam Yamashita, the company pairs no-code recording with autonomous AI agents that generate test cases from requirements, write test code, and self-heal tests when the underlying app changes. With offices in San Francisco and Tokyo, Autify serves web and mobile teams at companies like DeNA, NEC, Yahoo, and ZOZO, and has raised roughly $29-32M across seed, Series A, and a 2024 Series B.
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.
Provar
Provar is a UK-founded software company that builds test automation and quality management tools purpose-built for the Salesforce ecosystem. Its low-code platform - anchored by Provar Automation and Provar Manager - lets both manual testers and developers create resilient, metadata-aware tests across UI, APIs and data layers that survive Salesforce's three-times-a-year release cadence. Founded in 2014 by veterans of highly regulated banking projects, Provar has grown into the category leader for Salesforce QA, and was first to market with automated end-to-end testing for Salesforce's Agentforce AI agents.
Checksum.ai
Checksum.ai is an AI software-testing company that automatically writes and maintains end-to-end tests for web applications. Its AI agents learn from real user sessions to generate production-ready Playwright and Cypress tests, then auto-heal them when the app changes - so engineering teams get broad test coverage in days instead of months and stop babysitting flaky test suites. Founded in 2022 and built inside the super{set} startup studio, the San Francisco company serves developers and QA teams who want to ship fast without breaking things.
TestSprite
TestSprite is a Seattle-based startup building an autonomous AI testing agent that validates AI-generated code. Its agent plugs into AI IDEs like Cursor, Claude Code, and VS Code via an MCP server, then autonomously writes test plans, generates and executes tests in the cloud, diagnoses failures, and feeds fixes back to the coding agent. Founded in 2023, TestSprite has raised $8.2M total, including a $6.7M seed led by Trilogy Equity Partners in October 2025, and serves 35,000+ users. It positions itself as the 'testing backbone' of the AI-native development era.
Distributional
Distributional is an enterprise AI testing platform that uses adaptive, statistical analysis of production traces to catch behavioral drift and regressions in AI agents and LLM applications. Founded in 2023 by former Intel AI software GM Scott Clark, the company helps Fortune 500 teams ship generative AI with confidence by treating reliability as a continuous test problem rather than a one-shot benchmark.
QASource
QASource is a Silicon Valley-based software QA and testing company that gives engineering teams a full quality-assurance department without the cost and hassle of building one. Founded in 2000 by Rajeev Rai, the firm runs a hybrid onsite-offshore model - U.S. management and embedded QA engineers paired with technical talent in India and Mexico - delivering everything from manual, automation, performance and security testing to AI-augmented test automation, LLM evaluation, RLHF tuning, red teaming and RAG application testing.
