Your teams don’t have time to build annotation pipelines from scratch. So, we supply the labeled data, enabling your engineers to stay focused on model development, not data ops.
With SunTec.AI, you get high-accuracy training data for AI at production scale across image, video, text, audio, and 3D sensor inputs. Whether you're working with multiple data types or applying ML to a new industry, use case, or dataset type that may not have well-defined labeling standards yet, our data annotation team ensures that you can move from data collection to model testing without operational slowdowns. The training data you get is immediately usable, organized, consistent, and context-aware, so you don’t need to rework or clean it later. Our workflows are designed for speed and consistency, powered by domain-trained annotation teams, secure infrastructure, and ML-assisted tools, and aligned with your taxonomies, QA standards, and delivery timelines.

Read MoreWe offer a full spectrum of annotation types, from simple shapes to domain-specific taxonomies, so your training data is both technically precise and contextually relevant. Whether you're building models for computer vision, NLP, or multi-sensor fusion, we ensure your labels align with real-world application logic.
Bounding Boxes, Polygons, Cuboids, Keypoints
Geometric annotation formats for object detection, localization, and pose estimation across 2D and 3D data (e.g., vehicles in traffic scenes, facial landmarks in biometrics, product placement in retail).
Semantic & Instance Segmentation
Pixel-level labeling for scene understanding and object differentiation in high-density environments (e.g., tumor regions in medical imaging, road elements in AV data, crowd analysis in public spaces).
Domain-Specific Taxonomies
Custom label structures tailored to your use case and industry context (e.g., anatomical structures in radiology, SKUs in retail, pedestrians and signage in autonomous vehicle data).
Annotation at scale isn’t just about labeling—it’s about managing complexity, minimizing risk, and delivering consistent quality under production demands. Our infrastructure, processes, and compliance posture are engineered to give ML teams the operational edge they need to ship faster with confidence.
Quality Assurance You Can Trust
We implement rigorous, multi-layered QA protocols to ensure accuracy and consistency—no matter the data volume or domain complexity.
Enterprise-Grade Security & Compliance
Our AI data annotation practices meet the highest standards for data privacy, access control, and regulatory readiness.
Flexible Delivery that Fits Your Stack
Whether you're in prototyping or production, our delivery models adapt to your pipeline needs.
From autonomous driving to clinical diagnostics, our annotation services are built to support mission-critical ML applications. We adapt to the data types, compliance needs, and labeling complexity of each domain so your models are trained on inputs that reflect real-world conditions and outcomes.
