**Voted #1 Testing Partner**

## A crowdsourcing model 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 a fully managed testing model built to keep engineering teams focused, uncover issues that matter, and move high-quality releases out the door faster.

## On-demand expertise, available when and where you need it

Testlio’s community is the backbone of our managed crowdsourced testing platform. With only the top 3% of applicants accepted, we’ve built a global team of 10K+ vetted experts across 150+ countries who know their domains, understand their markets, and are rewarded for testing thoughtfully, not just checking boxes.

## Extensive real-world validation for your most demanding releases

Get broad, reliable coverage across devices, payments, and global user flows. Our deeply skilled testers work in real-world environments to uncover high-impact issues across your entire product lifecycle.

****Manual testing****

Deploy vetted, domain-aligned testers who embed directly into your release cycles. Our experts go beyond checklists to uncover real usability and functional issues at speed and scale.

****Test automation****

Build and maintain automation that keeps pace with your product. We help you design reliable strategies that deliver repeatable results, reduce risk, and support faster releases.

**Payments testing**

Validate the entire customer buying journey and not just transactions. Test everything from functional flow and integrations to usability and compliance issues with real users and payment methods.

****AI testing****

Make AI features safe, reliable, and ready for real users. Evaluate model outputs, train data sets, and simulate edge cases with human insight at every step.

****Functional testing****

Ensure your core features work as expected. Test across devices, browsers, and environments to confirm behavior under real conditions.

**Localization testing**

Release experiences that feel native in every market. Validate translation accuracy, layout, regional behavior, and cultural context with in-market testers.

### What is Code Coverage & How to Calculate It?
