Data Annotation Services
Enterprise-grade data labeling across every modality. Managed teams deliver 98%+ accuracy with full auditability — so your AI models train on data you can trust.
Every Modality, One Trusted Partner
Centric Labs provides managed data annotation services spanning images, video, text, audio, and 3D point clouds. Our dedicated teams combine domain expertise with AI-assisted tooling to deliver production-ready labeled datasets that meet the accuracy, speed, and security requirements of enterprise AI programs. From computer vision pipelines to LLM fine-tuning workflows, we handle annotation complexity so your ML engineers can focus on model development.
- Multi-modal coverage: image, video, text, audio, and 3D
- Named, managed teams — not anonymous crowdsourcing
- Four-stage quality pipeline with 98%+ accuracy SLAs
- SOC 2 aligned security with air-gapped options
- Flexible output formats: COCO, Pascal VOC, YOLO, custom
