Data & Annotation
Accurate training data, labelled by people who follow the rubric.
Annotation teams that label images, video, text and audio to your guidelines, with consistency checked every day.

95%+
Target label accuracy on the agreed rubric
Overview
We build a dedicated team for each project and train it on your rubric before any production work starts.
Annotators label a calibration set first and their answers are compared with yours. Anyone who falls short is retrained or reassigned.
Production batches go through multi-pass review, with a second annotator, hidden gold tasks and agreement tracked by label type.
Whenever your guidelines change, we run a calibration session the same week.
Specialist work, such as medical imagery, legal documents or African-language text, goes to suitably qualified annotators.
