UiPath
UiPath taught software robots to copy clicks. Now it wants to conduct the whole office - AI agents, old systems, APIs and the humans who still know when to say no.
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.
Agama Solutions Inc
Agama Solutions has spent two decades selling the least glamorous - and often most necessary - layer of digital transformation: the people, testing discipline and delivery capacity that turn a technology plan into working software.
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.
Epidata
Epidata is an Argentina-founded, privately owned technology company specializing in innovation outsourcing - transforming organizations through software architecture, engineering, and applied knowledge. Since 2003 it has grown into a multinational with roughly 700+ staff and offices across Latin America and San Francisco, delivering software development, staff augmentation, DevOps, big data, machine learning, RPA, testing and digital transformation to enterprises and governments including JP Morgan, HSBC, Walmart, Telecom, Tenaris and Asana.
Forte Group
Forte Group is an AI-first software development and consulting firm founded in 2000 and headquartered in Boca Raton, Florida. Bootstrapped since day one, it delivers custom software, data and analytics, quality engineering, and Salesforce services through roughly 800-900 engineers across a dozen locations in the Americas and Europe. The company built its reputation on outcome-based engineering - tying its work to measurable business results rather than billable hours - and now embeds AI across the full product lifecycle for clients in finance, healthcare, logistics, retail, SaaS, and beyond.
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.
Trunk
Trunk is a San Francisco developer-tools company building a suite that keeps continuous integration reliable at scale. Its two flagship products - a parallel Merge Queue that batches and tests many pull requests at once, and Flaky Tests, which automatically detects and quarantines unreliable tests - target the bottlenecks that slow engineering teams as they ship more code, increasingly with AI assistance. Founded in 2021 by ex-Uber and ex-Google engineers, Trunk raised a $25M Series A led by Initialized Capital in 2022 and counts Brex, Faire, Zillow, and Gusto among its users.
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.
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.
