As generative and agentic AI reshape software development, the pressure on quality engineering has increased sharply. TestMu AI, earlier known as LambdaTest, is positioning itself at the centre of this shift with a full stack agentic AI platform for software testing. Founded in 2017 by Asad Khan and Jay Singh, the company moved its headquarters from Noida to San Francisco early on to focus on the US market. It serves customers such as OpenAI, Boomi, NVIDIA and Estee Lauder. In December last year, Mudit Singh was elevated to co founder as the company rebranded to TestMu. Today, it supports over 2.8 Mn developers and testers across 132 countries.
TestMu began as a cloud based testing infrastructure provider that helped teams run automated test suites faster. “A developer would ship a feature, trigger a test suite and then wait half a day for results,” Singh recalls. The company built an enterprise grade parallel execution infrastructure that reduced delays. By redesigning its architecture with intelligent orchestration and caching, Singh claims TestMu cut execution time by nearly 70%. It also introduced analytics powered by machine learning to detect flaky tests and failure patterns. Over time, this evolved into Kane AI, which allows users to describe test needs in natural language. Kane AI can ingest Product Requirement Documents and generate automation workflows, while keeping humans in the loop.
Adoption of generative AI remains cautious in sectors such as BFSI and healthcare, so TestMu continues offering deterministic machine learning models for regulated industries. It also generates synthetic data to reduce compliance risks. Partnerships with Accenture, Infosys, Wipro and Capgemini support enterprise governance. More than 30% of its users are based in India, including Bajaj Finserv, Airtel, Edureka and Whatfix. The company offers an agent based AI pricing model where 1,000 agents cost $199 per month, while infrastructure pricing is based on parallel execution capacity. Singh said the company has grown at 110% annually. Its India revenue rose from ₹175 crore in FY24 to ₹177 crore in the year ending March 2025, with 50% driven by AI led products. It has raised nearly $100 Mn, including a $38 Mn Series C round in 2024.
With AI coding tools enabling instant app creation, testing has become critical. GitHub now has over 4.7 Mn paid Copilot users, up 75% year over year. “You can build an app in two minutes,” the company explains. “But it may take two hours to test whether it actually works.” Singh added, “End users do not care whether an app was built using traditional coding or generative AI.” As AI generated code scales rapidly, TestMu sees expanding demand for automated and agentic AI driven quality engineering.
