Top Data Annotation Companies

A machine learning model is only as accurate as the labels it learns from. Data annotation services companies supply those labels at volume: boxes, polygons and masks on images, object tracking across video frames, 3D cuboids in LiDAR point clouds, entities and intents in text, transcripts and speaker turns in audio, and preference rankings and written responses for training large language models. AI teams outsource it when in-house labeling cannot keep up, when they need domain experts such as radiologists or linguists, or when a new model needs a large training set.

Compare data annotation providers here on the label types they have delivered at scale, how they measure quality, and where and how your data is handled.
