Frequently asked questions
We combine the reach of a global crowdsourced community with a powerful AI-powered platform to help you release faster and at scale. In-market testers in over 150 countries, intentionally matched to your needs, validate your digital products across the languages, payment methods, and devices your customers rely on. Our global community is highly vetted and trained to find critical localization mistakes that others can’t. A dedicated client team manages scoping, execution, recruiting, and reporting end to end. This ensures consistency, speed, and accountability across every market you validate.
LeoMatch™, our AI-powered talent orchestration engine, automatically selects testers by language proficiency, in-country residence, market familiarity, device access, platform expertise, and product domain. Every engagement includes a mix of consistent testers who know your product and fresh testers who bring new market perspectives.
Testlio's pricing model is designed to help you get the most out of your partnership with us. It’s built on two factors. A platform fee covers your LeoCore access — tester matching, reporting, integrations, orchestration and your account management team. An annual consumption fund covers the testing work itself. Whether you need quality management, specialized testers, experts in a specific region, or a specific number of testing hours, your consumption fund supports it. What's included in each scales with your package: Essential, Advanced, or Enterprise.
Timelines depend on the number of markets, languages, and platforms in scope. We involve our delivery team early to align on priorities, sequence market coverage, and launch testing cycles as soon as possible.

LeoCore, our proprietary AI-powered platform, orchestrates the entire testing process, from test runs and work opportunities to recruitment, execution, and reporting. By automatically surfacing the best-fit testers for each engagement, streamlining onboarding, and learning from historical project data, it removes friction and enhances precision at every step. This means fewer manual tasks, more strategic oversight, and dramatically faster, more scalable delivery.
