Lambdatest

TestMu AI, formerly LambdaTest, operates a cloud-based software quality engineering platform that lets engineering teams plan, author, execute and analyze tests for web, mobile and AI applications. Its historical core is a browser and app testing cloud that runs manual and automated tests across thousands of browser, operating system and real-device combinations, alongside HyperExecute, a test execution and orchestration cloud the company says runs tests up to 70% faster than conventional cloud grids with 2.5x faster test resolution and 60% quicker error detection.

The product line spans Test Manager for AI-assisted test management with Jira syncing; Kane AI, a GenAI-native agent that plans and authors tests from natural-language prompts, tickets, diffs, documents, images or media and converts them into automation; Kane CLI and an MCP server for terminal, CI pipeline and coding-agent workflows; Agent Testing, a multi-agent product that evaluates chatbots, voice agents and inbound/outbound calling agents for issues such as hallucinations, bias, toxicity and compliance; a real device cloud covering iOS and Android; and SmartUI visual testing, API, accessibility, performance and cross-browser testing. Test Intelligence adds AI-based error classification, auto-healing, flakiness detection and analytics. The platform advertises 120+ integrations and shared cloud, private cloud and on-premise deployment options.

The company was founded in 2017 according to its funding announcements, and rebranded from LambdaTest to TestMu AI on January 12, 2026, positioning itself as a full-stack agentic AI quality engineering platform. The lambdatest.com domain continues to redirect to testmuai.com with backward-compatible API endpoints.

Founding story

Co-founder and CEO Asad Khan has over 10 years of experience in the software testing industry; he previously helped build 360logica into a multi-million dollar business within five years before its acquisition by Saksoft at the end of 2014, and earlier worked as a Lead Engineer at GlobalLogic on quality assurance for an enterprise wealth management product company serving banks including Bank of America, Wachovia, PNC, Wells Fargo and BNY Mellon.

Business model

Subscription-based B2B SaaS: customers pay for access to a hosted testing cloud (browser, real device and orchestration infrastructure) plus AI testing agents, with plans and tiers unchanged through the TestMu AI rebrand. Deployment is offered as shared cloud, private cloud or on-premise, and the company also sells professional services covering onboarding, migration and optimization.

Recurring platform subscriptions across pricing tiers, supplemented by expert-led professional services. Roughly half of revenue is reported to come from AI products such as Kane AI rather than traditional testing infrastructure.

Traction

Reported 15,000+ customers and 2.3 million+ users across 130+ countries at the end of 2024, with about 105% year-over-year growth and more than 1.2 billion tests executed on the platform since inception. Later company materials cite 3 million+ users globally, and third-party coverage of the 2026 rebrand cites 18,000+ enterprise customers and 110% year-over-year growth, with about half of revenue from AI products.

Latest developments

The January 12, 2026 rebrand to TestMu AI repositioned the company around agentic AI, with Kane AI as the flagship product and Kane CLI extending flows to the terminal, CI pipelines and coding agents. A new Agent Assurance capability for verifying what AI agents actually did is being offered via waitlist, and the company has added an agent-testing product for chatbots, voice and calling agents. In 2025 it was named a Challenger in the Gartner Magic Quadrant and recognized in The Forrester Wave for Autonomous Testing Platforms.
