Nanjing Silicon Intelligence Technology Group Co., Ltd. (南京硅基智能科技集团股份有限公司), known in Chinese as Silicon Intelligence (硅基智能), is China’s largest provider of digital-human agents: by 2024 revenue from digital-human agent solutions it ranked first in China, with a 32.2% share of the market. It was incorporated on 8 August 2017 as Nanjing Guiji Intelligent Technology Co., Ltd. (南京硅基智能科技有限公司) and converted into a joint-stock company under its present name on 18 February 2025. It is based at No. 20 Fengxin Road, Yuhuatai District, Nanjing; its website is guiji.ai, and its DUIX platform has its own site at duix.com.
It was founded by Sima Huapeng (司马华鹏), who holds a bachelor’s degree in electrical engineering and automation (June 2003) from Nanjing University of Aeronautics and Astronautics (南京航空航天大学). He is executive director and chief executive, holds 26.54% of the shares and controls the votes of a further 10.28% held by the share-incentive platform Jiaxing Guiyu (嘉兴硅语), and is named as an inventor on 129 patents.
The company first applied to list in Hong Kong on 31 October 2025; after that application lapsed it applied again on 21 May 2026, with CMB International (招银国际) and DBS as joint sponsors. Its June 2025 Series D round valued it at about RMB 3.15 billion.

The company calls its digital-human agents “silicon-based labour” (硅基劳动力): AI workers that take the place of people in voice calls, video, livestreaming and real-time conversation. It sells them as silicon-based intelligent voice, digital-human video, digital-human livestreaming, real-time digital-human interaction and fully automatic content production, mostly as locally customised projects. Its real-time interaction runs on DUIX, a platform launched in June 2022 and open-sourced on GitHub, and on DUIX ONE, launched in November 2024. In April 2025 it bought the domain duix.com for a reported US$10 million and launched DUIX there as its next-generation digital-human interaction infrastructure. The site’s privacy policy names Duix Lab Inc., a company not among the subsidiaries listed in its prospectus, as duix.com’s owner and operator.
Its deployments include Nan Nan (楠楠) and Jing Jing (晶晶), digital-human employees of Bank of Nanjing and among the first in China’s financial sector; an AI follow-up platform for community health screening that it donated in Wuhan in February 2020; and the digital-human mascot of the Nanjing Marathon. In March 2025 it was one of four co-developers, with Changzhou Hospital of Traditional Chinese Medicine (常州市中医医院), Nanjing University of Chinese Medicine’s School of AI and Information Technology and China Mobile’s Changzhou branch, of Dr. Meng (Dr. 孟), a TCM digital human built on the Menghe school’s academic system (Modern Express).
