ISO 27001 data annotation services for AI and ML teams in regulated industries
Bounding boxes, polygons, segmentation masks, keypoints, landmarks, and classification labels for detection, segmentation, and classification models, with human validation on every batch.
Frame-by-frame boxes, masks, keypoints, and identity-consistent object tracks for detection, tracking, and action-recognition models, validated at the sequence level.
3D cuboids, point cloud segmentation, drivable-area labeling, and object tracking for robotics, autonomous mobility, geospatial, and industrial AI programs.
Text-region labeling, document segmentation, handwriting annotation, structured field extraction, plus LLM evaluation with calibrated rubrics and GenAI alignment data.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
