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.

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
