The power of the crowd, minus the chaos

Most crowdtesting feels messy. Too many testers, not enough ownership, and results that are hard to trust. Testlio is built to fix that, with a managed model that keeps quality high and effort low.

Enterprise-grade security

Testlio is ISO/IEC 27001:2022 certified, with rigorous data governance built into every engagement, so your data stays protected, structured, and fully compliant.

How do our testers differ?

Our expert crowdsourced testers make a world of difference. They are highly vetted, consistent, and incentivized to test more thoughtfully.

Expert testers

Freelancers with Testlio are vetted, validated, and rated. They are not gig workers. Only 3% of applicants to the Testlio Community are accepted to client projects. And all freelance testers receive a 0-100 rating, along with multiple sub-ratings based on critical performance criteria.

Consistent runs

Testlio uses a high percentage of consistent testers run-to-run—while also rotating new testers for fresh insights and perspectives. Most other crowdsourced testing solutions leverage “whoever is available” models for testing delivery, creating inefficiencies in testing and escaped issues, often at the most critical release moment.

Thoughtful compensation

Our testers are paid by the hour, equipping them to tackle deep quality issues. And Testlio benchmarks the testing industry regularly, striving to pay in the top quartile based on location, experience, role, and needs.
