What Datatang does

Datatang (数据堂), founded in 2010 and headquartered in Beijing's Haidian District (Aobei Technology Park), is a privately held B2B AI training data services provider serving global enterprise customers building computer vision, speech, natural language, multi-modal, and large language model (LLM) systems. The company operates a full-stack service portfolio built around four pillars: (1) pre-built copyright datasets covering speech recognition/synthesis across 200+ languages and dialects (2M+ hours), computer vision (~1M IDs / 800TB), OCR, pronunciation dictionaries, and natural language understanding; (2) data customization services spanning multi-modal, LiDAR point cloud, street view, OCR, behavior/identity recognition, and speech; (3) vertical-specific industry solutions for autonomous driving, smart customer service, smart home, intelligent entertainment, new retail, and smart healthcare; and (4) the proprietary Shujiajia (数加加) data annotation platform supporting 2D, 3D, and 4D labeling with algorithm-assisted pre-recognition that delivers 30%+ efficiency improvements.

Underlying technology centers on the Shujiajia platform's algorithm-assisted pre-identification pipeline and an 8,000 sqm dedicated physical data collection factory for embodied AI/robotics research, complemented by an in-house professional annotation workforce and medical-specialist labeling teams. The company holds ISO9001, ISO27001, and ISO27701 certifications and secures national IP certificates on finished datasets, with a subject-authorized consent regime that addresses enterprise buyer due diligence.

Datatang's go-to-market is a sales-led enterprise motion: direct consultation via the website, customer service system, phone (13051623904), and email ([email protected]) under quote-based custom pricing on multi-year contracts. Revenue mechanics combine one-time copyright dataset licensing, professional services for custom collection/annotation, and recurring/subscription access to the Shujiajia platform and training edition. The company claims 5,000+ global enterprise customers served and a product footprint spanning China, Japan, Korea, the US, UK, France, Germany, and Russia.
