Get the coverage and depth you need to release without doubt

Built for accountability and scale
Testlio was founded by Kristel and Marko Kruustük, who were frustrated by the lack of pride and structure in most crowdtesting platforms. They believed quality work should be valued, supported, and managed, not left to chance.
That belief paved the way for an AI-powered crowdsourced testing model that delivers high-velocity human insights to keep engineering teams focused, uncover issues that matter, and move complex global releases out the door faster.
To manage testers, results, and releases
LeoCore is Testlio’s proprietary AI-powered platform that orchestrates testing from end-to-end and allows us to deliver unmatched value from the very first cycle. It handles everything from matching the right testers and managing test cycles to analyzing results and surfacing predictive insights at the right time, helping you make better release decisions. Bi-directional integrations and MCP support enable LeoCore to seamlessly integrate with the tools and workflows you already use, so you get unified results and actionable intelligence without overhauling your processes.


Available when and where you need it
Testlio’s community is the backbone of our managed crowdsourced testing platform. Our vetted testers and specialized payments, AI, and localization experts bring consistency, the right devices, product context, and domain experience to deliver actionable insights you can trust. With complete transparency into tester performance and intelligent talent matching powered by LeoMatch™, Testlio’s community integrates directly into your testing workflows to expand coverage without long ramp-ups, management burden, or the inconsistency of traditional crowdtesting platforms.

Testlio: Where quality meets passion
“Testlio is very proactive. Very thoughtful. Detail-oriented. It’s like having someone who really cares about the quality of the product and how to test it better. That is really rare to find in a vendor.”
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.”
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'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”
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."
