Jinglianwen Technology

Jinglianwen Technology, established in 2012, operates as an artificial intelligence data service provider. The company's business has progressed through three main phases: starting with biometric algorithms, moving to data collection and annotation, and now focusing on the production and operation of high-quality AI datasets. The firm's CEO is Liu Yuntao.

Jinglianwen Technology serves clients in sectors requiring large-scale, high-quality data, including autonomous driving, healthcare, and companies developing large AI models. A core part of its strategy involves the production and operation of public data, positioning itself as a key partner for local governments to extract value from their data assets. The company has developed the "Solar Sence" intelligent corpus engineering platform, a full-chain system that manages data aggregation, governance, development, and trading across various data types like text, audio, images, and video.

The company's business model revolves around providing high-quality, annotated datasets and data services. This is supported by establishing annotation bases in key industry verticals to ensure a stable supply of expert-annotated data. In May 2025, Jinglianwen Technology secured a Pre-A funding round of tens of millions of yuan from a fund associated with the Hangzhou Jintou Group. These funds are allocated to expanding public data operations, enhancing its intelligent corpus platform, and building out its vertical-specific annotation bases. The company has also collaborated with Huawei Data Storage to launch an AI data lake solution.
