Outsource Data Annotation Services

Train your AI/ML models with accurate and well-structured datasets at cost-effective prices

We provide fully managed data labeling services

AI-enabled applications and machine learning models need massive amounts of labeled data to function effectively. Turning unstructured data into well-configured, meaningful, and organized data requires an optimal balance of resources and skills.

Our annotation team addresses the problem by creating accurate, high-quality training data. We use state-of-the-art labeling tools to convert unstructured, raw data into meaningful datasets to assist machine learning models in identifying, tracking, and classifying objects of interest.

Our annotations find applications across diverse industry verticals, including eCommerce, finance, automotive, logistics, and healthcare.

Case study

Annotate live streams for improved traffic management

The client (a UK-based data analytics company) approached us for pre-recorded and live stream data annotation for a road planning and traffic management solution. We analyzed the requirements closely and assigned a fairly large team to annotate videos of moving vehicles under different exposures and frames. The resultant dataset was tested for quality and accuracy and delivered on time. It helped the client’s solution predict traffic-related issues like congestion, accidents, road planning, and lane movement.

Domain-specific use cases of our data annotation services

Autonomous vehicles

Self-driving vehicles rely on machine learning models to detect lanes, signals, pedestrians, and other objects in an image or video. Annotation trains and feeds the operating algorithms for such machines with structured data for effective functioning.

Facial recognition software

Machines can easily use annotated data to identify facial features and markers. It helps tech companies to enhance the security of their smartphones, laptops, computers, and other gadgets by integrating face unlock.


Annotated and labeled MRIs, CT scans, X-rays, and other critical reports assist medical AI-based software in diagnosing diseases and suggest treatments.

eCommerce & retail

eStore owners can use annotated data to build solutions that can automatically classify, categorize, and track products, smoothen the checkout process, manage inventory, and integrate visual search.


Data annotation for AI-based models in agriculture can unveil innovative and improved ways of cultivation and farming, such as weed or disease detection in crops, livestock management, seed selection, and crop growth monitoring.

Logistics & supply chain management

Precisely annotated datasets help train AI models to help simplify operations in the logistics industry, like tracking goods, improving security and inventory, detecting damages, and optimizing routes.
