Hillside Technology Limited, the engineering entity behind bet365, has deployed TestMu AI as its unified software testing platform, covering device compatibility, automation stability, and production release validation across the operator’s global operations.
What the Platform Does
TestMu AI, formerly known as LambdaTest, describes itself as a full-stack agentic AI quality engineering platform. The tool consolidates testing across hardware configurations, operating system versions, and screen resolutions, addressing the device fragmentation challenge that operators serving large mobile user bases face at scale.
For bet365, which processes hundreds of production releases per week, the primary requirement was platform reliability and broad device coverage. The deployment replaces a multi-tool testing setup, removing what Joanna Ward, Head of Software Testing at bet365, described as the friction of switching between tools.
“By unifying our testing onto a single platform, we’ve eliminated the operational friction of tool-switching and achieved significantly higher stability in our automation. TestMu AI’s performance and availability are exceptional, and their team’s support has allowed the platform to scale beyond our initial expectations. It is now a versatile asset used even for our internal application management.” — Joanna Ward, Head of Software Testing, bet365
Context: Mobile Complexity at Scale
bet365 was founded in 2000 and has built its competitive position substantially on technology infrastructure. Maintaining consistent product performance across an expanding range of mobile devices is a recurring engineering cost for large operators, and one that grows as mobile becomes the dominant access channel for sports betting and casino products.
The global online gaming market is projected to exceed $150 billion by 2030, with mobile growth cited as a primary driver of that expansion. Operators at the scale of bet365 need testing infrastructure that can keep pace with release velocity without introducing instability.
The TestMu AI deployment at Hillside Technology also extends to internal application management, indicating a broader operational scope than standard product QA.
TestMu AI’s Position in the Market
TestMu AI positions itself at the intersection of AI-assisted automation and device testing infrastructure. The rebranding from LambdaTest reflects the platform’s shift toward agentic AI capabilities, where automated agents carry out testing sequences with reduced manual intervention. The bet365 partnership is a significant enterprise reference for the platform, given the operator’s scale and engineering reputation.
The deployment adds to a pattern of large operators formalising their AI tooling across engineering functions. For operators considering similar consolidations, the bet365 case provides a reference point for what unified platform testing looks like at high release cadence.

Bet365’s track record of building proprietary infrastructure has been a recurring theme in industry analysis. Earlier coverage of how technology partnerships are reshaping operator capabilities is available in the Tequity RGS platform deal with EXCO and in reporting on how SoftSwiss helped Stake scale its technical infrastructure.
