The go-to for localization testing partnerships

“Because of how flexible Testlio is and how many services you offer, I’ve partnered with Testlio for localization testing in my last two companies. I’ve shown up with Testlio as my location QA testing vendor for localization and then the engineering team wanted to expand the collaboration with Testlio to functional testing and location testing.”

Nicole Kittle Broe
Director of Localization

Testlio’s Flexible Crowdsourcing: Optimized QA Efficiency

“What I really appreciate about Testlio’s crowdsourcing model is that we have a lot of flexibility in how we mix and match resources to get work done. We can rely on Testlio to scale our testing resources for that period when we have big releases and then scale it down when we don’t need that extra resourcing. There’s basically an endless list of things like this, where we can optimize our QA effectiveness with Testlio.”

Annyce Davis
VP of Engineering at MeetUp

Integrated & scalable testing solution

“Testlio works like a test organization integrated directly into our team at a fraction of the cost of hiring a test team. Furthermore, it scales as we need more testing resources and shrinks back down when we don’t. We’ve found them to be flexible and capable of keeping the quality of our application high.”

Patrick Kim
Engineering Manager
