What eSign does

eSign (e签宝), operated by Hangzhou Tiangu Information Technology Co., Ltd. (杭州天谷信息科技有限公司), is China's leading electronic signature and contract lifecycle management platform. Founded in 2002 and headquartered in Hangzhou, the company serves corporations, government agencies, and individual users with a cloud-based platform that supports multi-format signing (OFD, PDF, Word, Excel, HTML) across enterprise, financial services, government, healthcare, real estate, manufacturing, FMCG, automotive, education, logistics, and cross-border trade verticals. The platform claims 35% market share in China's electronic signature market per Frost & Sullivan's 2025 report — exceeding the combined share of the next four competitors — and is ranked first in Asia Pacific and sixth globally.

The product portfolio centers on the "签管一体化" (sign-and-manage integrated) electronic contract cloud platform, supplemented by eSign.AI Global Signing (covering 100+ countries for cross-border signing), an AI Super Contract Assistant (intelligent contract agent for drafting, review, signing, and management), identity verification services (30+ capabilities including face recognition and bank card verification), blockchain-based data evidence preservation (up to 20 years post-expiration), legal services, iSignature for OA and e-government, proprietary cloud deployment, print control IoT devices, an OpenAPI platform (100+ endpoints), and DingTalk Smart Contract (a co-built DingSign product). Underlying technology combines cloud infrastructure with proprietary AI capabilities including OCR, NLP-based contract review with low/medium/high risk classification, AI collaborative drafting, AI quick signing, multimodal identity verification (face/liveness/video dual-recording), and a Contract Large Model recognized by IDC as a typical office AI agent application.

The business model is primarily SaaS subscription with usage-based contracts on top: Basic version at 980 yuan/year for teams under 10, with Professional, Advanced, and Flagship tiers priced on quote for growing, mid-large, and group enterprises; contract volume packages range from 650 yuan (100 contracts) to 10,000 yuan (2,000 contracts); iSignature is sold as a one-time enterprise license; and API integration services are sold as tiered recurring packages. Go-to-market combines product-led growth (freemium trial) with sales-led enterprise motion (dedicated consultants for custom solutions), channel partners (agents, individual partners, platform partners with commission compensation), and embedded distribution via DingTalk, WeCom, Feishu, Kingdee, Lanling, and 15+ ERP/CRM integrations. The company employs 501-1,000 staff and serves over 200 companies on the Fortune China 500 list, with named customers including Huawei (deployed across 60+ countries), Alibaba, Toyota, Sony, Huaxia Bank, Geely, ZhongAn Insurance, FESCO Adecco, Vanke Property, and Zhejiang Provincial Government.
