Data Annotation Services

Data Annotation Services That Scale With Your AI Ambitions

Centric Labs provides managed data annotation services across every data modality — images, video, text, audio, and 3D point clouds. Our dedicated annotation teams combine domain expertise with AI-assisted tooling to deliver production-ready datasets that meet the accuracy, speed, and security demands of enterprise AI programs. From computer vision pipelines to LLM fine-tuning workflows, we handle the complexity so your ML engineers can focus on building models, not managing data.

Annotation Services Across Every Data Modality

Image Annotation: bounding boxes, polygons, semantic segmentation, keypoints, and instance segmentation for computer vision. Video Annotation: frame-by-frame and interpolated annotation for object tracking, activity recognition, and autonomous driving. Text & NLP: named entity recognition, sentiment analysis, text classification, relation extraction, and document annotation. Audio & Speech: transcription, speaker diarization, emotion detection, and intent classification. 3D Point Cloud & LiDAR: cuboid annotation, semantic segmentation, and sensor fusion labeling for robotics and autonomous vehicles.

Multi-Tier Quality That Protects Your Model Performance

Every annotation passes through our four-stage quality pipeline: AI-assisted pre-labeling for consistency, senior annotator review, automated validation checks against your taxonomy, and random-sample audit by domain specialists. We track inter-annotator agreement scores in real time and provide full traceability for every label. Our standard is 98 percent or higher accuracy, with custom SLAs available for mission-critical use cases. Unlike crowdsourcing platforms where quality is an afterthought, quality is architecturally embedded in every Centric Labs engagement.

Your Dedicated Annotation Workforce

We do not rely on anonymous crowd workers. Every Centric Labs project is staffed by a named, trained, and managed annotation team. Your team includes a dedicated project manager based in the US or UAE, trained annotators with domain-specific onboarding, quality analysts embedded in the workflow, and a technical integration specialist for pipeline setup. This model ensures consistency, accountability, and the institutional knowledge that crowdsourcing cannot provide.

Seamless Integration With Your ML Pipeline

Our platform connects directly to your existing infrastructure via RESTful APIs. We support all major annotation formats — COCO, Pascal VOC, YOLO, and custom schemas. Data flows in, annotated datasets flow out, with full version control and audit trails. We also offer on-premise and air-gapped deployment for clients with strict data residency requirements.

Flexible Engagement Models for Every Scale

We offer three engagement tiers: Pilot, which includes a free proof-of-concept with up to 1,000 annotations to benchmark quality; Growth, which provides dedicated teams with monthly capacity commitments and volume pricing; and Enterprise, which delivers custom SLAs, security configurations, and embedded teams with full pipeline management. All pricing is transparent with no hidden per-annotation markups.
