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.
Testlio's Flexible Crowdsourcing
“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”
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.”

Testlio goes the extra mile!
“I like how easy Testlio is to work with. It is as if they already understand what you are looking for and are willing to go the extra mile to ensure their service is top notch.”
