Everything about TestGrid, answered

TestGrid is an end-to-end testing platform that combines real-device and browser infrastructure, test automation, test management, performance testing, API testing, visual testing, and AI-assisted testing. You can use it through cloud, hosted, private-cloud, on-premises, or hybrid environments based on your security, infrastructure, and testing requirements.

Harry Rao founded TestGrid in 2015 and serves as its CEO.

Software testing often requires separate products for device access, browser coverage, automation, reporting, performance validation, and test management. Your team may also need to maintain physical device labs and automation scripts that require frequent updates. TestGrid brings these activities into one platform, reducing infrastructure maintenance while improving coverage and shortening regression cycles.

From a clear market gap. Enterprises were investing heavily in digital products but had no scalable, secure, cost-effective way to test applications across real user environments. Large organizations, especially in banking, telecom, healthcare, retail, and other regulated industries, needed more control than public-cloud-only platforms could offer.

Harry Rao saw companies forced to choose between expensive legacy tools, public-cloud platforms that didn't meet enterprise security requirements, and manual QA processes that slowed releases. TestGrid was built to remove that trade-off: enterprise-grade testing infrastructure with flexibility, speed, affordability, and control.

You can create, import, run, and manage tests across real devices, browsers, APIs, and enterprise applications. Choose code-based automation, codeless authoring, record-and-playback, or AI-assisted workflows, then run tests manually, on a schedule, in parallel, or through CI/CD. TestGrid records the results and keeps your test assets and reports in one workspace.

TestGrid supports everyone involved in software quality, including manual testers, QA engineers, automation engineers, SDETs, developers, DevOps teams, test managers, application owners, and engineering leaders.

You can use TestGrid to test websites, web applications, native and hybrid mobile applications, mobile web applications, REST and SOAP APIs, and specialized workflows involving kiosks, POS systems, scanners, and connected devices. Supported methods include manual, automated, codeless, real-device, cross-browser, visual, API, regression, and performance testing.

Many testing products focus on one capability, such as device access, automation authoring, or performance testing. TestGrid combines testing software with the real-device, browser, and execution infrastructure required to run tests.

You can use it through shared cloud, dedicated hosting, private cloud, on-premises, or hybrid deployment. It also supports dedicated devices, secure tunnels, virtual USB access, reporting, test management, and AI-assisted workflows.

TestGrid began with a focused goal: simplify real-device and browser testing for enterprises. It grew into a full end-to-end platform — mobile app testing, web testing, automation, scriptless testing, performance testing, API testing, visual testing, test management, and enterprise-grade infrastructure.

Today the platform has evolved again, into an AI-powered testing ecosystem. With CoTester, AI agents understand requirements, generate test cases, execute tests, adapt to UI changes, and reduce maintenance across the software delivery lifecycle.

Before founding TestGrid, Harry Rao served as Director of Software Engineering at CGI, where his work covered cloud-native applications, mobile technology, IoT, and DevOps. He previously held a digital-solutions role at The Walt Disney Company and earned a master's degree in computer science from San Diego State University.

The classic challenges of building a capital-intensive SaaS business in a market where competitors had raised large venture rounds. TestGrid had to build sophisticated infrastructure, acquire devices, and support enterprise deployments while staying disciplined and resourceful. Harry also faced a personal version of the challenge: no strong venture capital network in the early days, and an engineering background that meant sales, marketing, positioning, and leadership all had to be learned through direct experience.

Harry Rao hosts 5 Minute Mentorship, a short-form podcast featuring insights from industry leaders, founders, and change-makers. Its episodes focus on entrepreneurship, leadership, career development, and practical lessons delivered in approximately five minutes.

Harry believes software testing will move from manual, script-heavy, reactive QA to AI-driven, proactive, self-healing quality engineering. AI agents will understand product requirements, generate tests, run them across real environments, detect defects, heal broken automation, and continuously improve as applications change.

TestGrid aims to be at the center of that transformation, combining real-device infrastructure, automation, AI agents, enterprise governance, and software delivery intelligence in one unified platform.

TestGrid was founded in 2015 to reduce the time and cost organizations spent managing physical device labs, disconnected testing products, manual QA processes, and high-maintenance automation scripts.
