Our data labelers can fully integrate into your existing team for a seamless working experience.

  • We make sure that each engagement between you and your data labeler begins with a trial period of up to two weeks. This means that you have time to confirm the engagement will be successful. If you’re completely satisfied with the results, we’ll bill you for the time and continue the engagement for as long as you’d like. If you’re not completely satisfied, you won’t be billed.
