Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
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.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
