Software testing startup LambdaTest raises $38M in Qualcomm-backed round

LambdaTest Inc., a startup with software for finding technical issues in applications, today announced that it has raised a $38 million funding round.

Avataar Ventures led the investment with participation from Qualcomm Ventures. The cash infusion follows a $45 million raise in 2022. According to LambdaTest, its total outside funding now stands at $108 million.

A web application that works well in Chrome may not necessarily load pages reliably when it’s accessed via Firefox. Quality inconsistencies can also emerge across devices and operating systems. As a result, developers must scan for application errors across every single browser, device and operating system combination that their customers use.

Performing the process manually can be prohibitively time-consuming. LambdaTest provides a software toolkit that speeds up the task by enabling developers to create automated testing scripts. The company says that tests created with its products can evaluate an application across thousands of device, operating system and browser combinations.

One of LambdaTest’s flagship features is a tool called HyperExecute. It can distribute software tests across multiple cloud instances and run them in parallel, which is faster than carrying them one after another. LambdaTest is promising an up to 70% speed improvement compared with other quality assurance methods. 

There are several tools on the market that offer similar capabilities. Usually, they rely on a centralized orchestration engine to manage the cloud instances in which tests are run. Data can take a significant amount of time to move between the orchestration engine and the instances, which slows down testing. According to LambdaTest, HyperExecute has an architecture that avoids such delays by reducing network hops, or the number of network devices through which data traffic must travel.

The company says its software also speeds up the process of writing software testing scripts. In August, LambdaTest launched a tool called KaneAI that allows developers to generate tests using natural language prompts. They can modify tests and translate them between programming languages the same way. 

Another AI tool, Test Intelligence, speeds up the task of interpreting software test results. The tool can automatically highlight technical data that suggests an application may contain a bug. It likewise flags tests that didn’t uncover any bugs but are inconsistent with earlier evaluations, which is often a sign there may be issue in a company’s quality assurance workflow. 

LambdaTest provides its core feature alongside more specialized tools. LT Browser is a browser for testing mobile websites the company based on Chromium, the open-source project that underpins Chrome. Another LambdaTest service, Real Device Cloud, allows developers to test apps on cloud-hosted handsets.

“As AI applications on the cloud and on devices become more prevalent, continuous testing with AI-driven automation is essential for accelerating release cycles,” said Quinn Li, the global head of Qualcomm Ventures.

LambdaTest will use its newly raised capital to enhance KaneAI and other components of its product suite. The company disclosed that its installed base comprises more than 2.3 million developers who have run more than 1 billion tests to date.
