About Us

We help global brands accelerate growth through our crowdsourced testing platform for web & mobile apps


Our Story

Internationalising software at speed has become increasingly challenging with the vast combination of new devices, operating system upgrades and global network providers. Not considering international markets results in a painful customer experience, slower international growth and opportunities for more agile local competitors to take market share.

We allow tech teams to leverage over 20,000 vetted professional testers with real devices in real environments in over 105 countries.

By taking a customer-focused approach to quality, hundreds of leading brands including Facebook, Microsoft, General Electric and iHeartMedia rely on Global App Testing’s platform to improve quality at a speed that allows Agile and DevOps teams to release faster and more often.

We’ve also gained worldwide recognition for innovations in the testing field - most notably inventing Testathons and QAOps. QAOps is the definitive book and philosophy on how the right QA can increase your speed, scale and global growth. Testathons, hackathons for testers, have now been run in over 35 countries with leading tech teams from the likes of King, Spotify and Instagram.
