What QIYUESUO.COM does

QIYUESUO.COM (branded as Contract Lock / 契约锁) is a Shanghai-based digital trust infrastructure platform operated by Shanghai Gengyan Network Technology Co., Ltd., founded in 2013. The company provides enterprise-grade electronic signature, electronic and physical seal lifecycle management, intelligent contract management, digital identity verification, and tamper-proof digital archiving for medium and large organizations. Its technology stack integrates NLP, large language models (referred to as "big models"), and RPA into a unified product suite, with proprietary seal-security mechanisms (non-storage of private keys, binding seals to user digital certificates) and an AI risk engine that monitors abnormal seal usage in real time.

The platform is sold primarily through direct enterprise field sales, with a self-service SaaS trial at the bottom of the funnel and an API-first open platform (open.qiyuesuo.com) for embedding into customer systems. Revenue derives from SaaS subscriptions, API/SDK integration fees, customized seal platform implementations, and professional services, with quote-based enterprise pricing. The company reports over 45,000 organizational customers across government, SOE, education, automotive, pharmaceuticals, inspection, and conglomerate segments, with named logos including State Power Investment Corporation, BYD, Johnson & Johnson China, Fudan University, China Certification Inspection Group, 360 Group, and Changhong Holdings. Distribution is amplified through standardized integrations with 500+ business systems, including deep partnerships with Yonyou BIP, Fanwei OA, Glodon, Mingyuan Cloud, iHRM, and a native HarmonyOS partnership with Huawei.

The company holds CMMI3, Level 3 Security Certification, Testing Classified Information System Products Certification, and ISO 27001, and operates with a lean headcount of 11-50 employees after a single disclosed 2016 funding round of $1.34M led by Weaver, indicating a self-funded, capital-efficient operating model. The founder is Lei Cong. Geographic reach is described as global via a cross-border signing scheme, though commercial activity is concentrated in China.
