Nanjing Silicon Intelligence Technology Group Co., Ltd. (南京硅基智能科技集团股份有限公司), known universally in Chinese as 硅基智能 (Silicon Intelligence), is China's largest digital human intelligent agent company, holding a 32.2% share of the domestic digital human intelligence market by revenue as of 2024. The company operates from No. 20 Fengxin Road, Yuhuatai District, Nanjing, Jiangsu Province, and maintains its primary web presence at www.guiji.ai.
Silicon Intelligence was founded in August 2017 by Sima Huapeng (司马华鹏), a serial entrepreneur and information security specialist who holds a bachelor's degree in Electrical Engineering and Automation from Nanjing University of Aeronautics and Astronautics. Sima serves as Executive Director and CEO and remains the company's controlling shareholder, holding approximately 26.54% of shares directly and controlling an additional 10.28% of voting rights through the employee incentive platform Jiaxing Guiyu. The company was originally incorporated as a limited liability company (南京硅基智能科技有限公司) and was restructured into a joint-stock company (南京硅基智能科技集团股份有限公司) in February 2025 in preparation for a public listing. On October 31, 2025, Silicon Intelligence filed a prospectus with the Hong Kong Stock Exchange, with CMB International and DBS Bank serving as joint sponsors, positioning itself as the first digital human company to seek a Hong Kong listing. As of its Series D financing round completed in May 2025, the company carries a valuation of approximately RMB 3.15 billion, having raised over RMB 1 billion in total across more than ten financing rounds. Key investors include Tencent, whose affiliate Linzhi Tencent holds 16.59% of shares as the largest non-founder shareholder, alongside Sequoia China, CMBC International, China Reform Holdings Corporation, Oceanpine Capital, Jiaxing Hi-Tech Zone Industrial Fund, Guoxin Fund, Zhongcai Qihu, Haison Capital, and Pengpai Capital.
The company's business is organized around the concept of "silicon-based labor" — AI-powered digital workers that substitute for human labor in voice interaction, video presentation, live streaming, and real-time conversational tasks. Its core technology stack encompasses automatic speech recognition, text-to-speech synthesis, voice cloning, voiceprint recognition, intent recognition, and emotion recognition, supported by AIGC-based digital human video generation. The company's proprietary DUIX platform (Dialogue User Interface System), which has been open-sourced for developer integration, serves as the foundational infrastructure for real-time digital human interaction and is deployable across Android, iOS, and large-screen terminal hardware. Additional products include the 硅语 (Silicon Speech) intelligent interaction platform, the 协呼 intelligent outbound calling platform, a virtual live-streaming platform, a digital human video production platform, an AI avatar cloning tool (AI克隆人), and VPPT, a video presentation tool. The DUIX ONE system, introduced as an optimized product model, has been cited in the prospectus as a driver of operational efficiency and adjusted profitability. On the developer side, the company operates under the identity GuijiAI on GitHub and Hugging Face, with the npm package published as duix-guiji and API endpoints hosted at robot.guiji.ai and api.us.guiji.ai.
Silicon Intelligence's services span approximately 40 industry sectors including banking and finance, insurance, telecommunications, government services, education, healthcare, and e-commerce. Notable deployments include "Nan Nan" (楠楠) and "Jing Jing" (晶晶), the first AI digital human employees in China's financial sector, developed in partnership with Bank of Nanjing, and an AI Smart Follow-up Platform deployed during the COVID-19 outbreak in Wuhan in 2020 for community health screening. The company also created the digital human mascot for the Nanjing Marathon. As of 2025, Silicon Intelligence holds 135 domestic and international patents, including key invention patents for telephone robot systems (ZL 2017 1 0792844.8) and intelligent outbound calling (ZL 2019 1 0724662.6), along with 32 AI-related invention patents, 5 utility model patents, and 30 software copyrights. Its lip-sync generation algorithm for digital human video was registered with China's Cyberspace Administration of China in April 2024 under filing number 320114226719301240019. The company holds designations as a National High-tech Enterprise and a Jiangsu Province Industrial Internet Demonstration Enterprise, both awarded in 2020.
Revenue grew from RMB 223 million in 2022 to RMB 655 million in 2024, with RMB 326 million recorded in the first half of 2025. The company achieved adjusted net profitability for the first time in the first half of 2025 at RMB 5.29 million, following adjusted net losses of RMB 46.22 million, RMB 29.41 million, and RMB 35.24 million across the three preceding full years. Revenue is generated almost entirely through direct sales, with the top client — a major state-owned telecommunications operator — accounting for 64.4% of total revenue in 2024, a client concentration risk acknowledged in the prospectus.
The English name Silicon Intelligence is the company's own designated rendering and is used in official documentation, Baidu Baike, and the majority of English-language press.

(used by Western financial data platforms for the original entity), Silicon-based Intelligence and Nanjing Silicon-based Intelligent Technology Group Co., Ltd.
