Annotation Support

What Annotation Support does

Annotation Support is a Chennai, India-based data annotation and labeling services company founded in 2019 as a specialized team carved out of parent Infosearch BPO. The company provides 19+ annotation service types spanning image (bounding box, polygon, semantic segmentation, cuboid, keypoint, instance segmentation, image masking), video, 3D LiDAR point cloud, geospatial, text, and audio modalities, alongside AI-assisted pre-labeling tools and a multi-layered quality assurance process. It serves AI/ML teams across autonomous vehicles, healthcare, agriculture, retail, logistics, finance, robotics, security & surveillance, sports, and academia, with active delivery to customers in the USA, Germany, Japan, Sweden, Singapore, Denmark, and the UAE.

The company operates an in-house 251–500 person workforce trained across multiple industry verticals, with all projects executed internally rather than crowdsourced. Its technology stack combines proprietary QA workflows, AI-assisted pre-labeling, and 3D LiDAR point cloud tooling, delivering reported operational benchmarks including 95%+ annotation accuracy, 35–50% reduction in annotation turnaround time, and 92%+ downstream model accuracy in customer deployments.

Annotation Support's go-to-market is sales-led and direct, with customers submitting requirements through a website quote form and receiving contact within 24 hours. Revenue is generated through a volume-based pricing model in which clients purchase data points in tiers (lower per-unit price at higher volume), pay 100% upfront before work begins, and consume purchased volume over a 30-day window. The customer base includes enterprise logos (GE, Nokia, Western Digital, BIC), more than nine academic and research institutions (including University of Washington, UC Davis, Seoul National University, IISc, and IIT Patna), and at least one startup (Gist). The company has no external institutional funding, no disclosed revenue, and operates as a wholly-owned strategic unit within Infosearch BPO.

Revenue model

1. Data Points Purchase Model: Clients purchase data points based on volume requirements. Price per data point decreases with higher volumes (volume-based pricing). Work validity is 30 days from invoice date. Daily volume calculated as purchased volume divided by 30. 100% payment collected before work execution begins. Errors reported within 2 business days are rectified at no extra cost; errors reported later are charged per slab rate.
