Unisound (云知声, 09678.HK) is a Chinese AI company founded in 2012 that builds conversational AI products and solutions for daily-life and healthcare scenarios, serving clients including insurance providers and over 100 hospitals . Its technical backbone is the "UniBrain" platform: a BERT-based model called UniCore launched in 2019, succeeded in 2023 by UniGPT ("山海"), a 60-billion-parameter multilingual, multimodal LLM . The company listed on the Hong Kong Stock Exchange on June 30, 2025, at HK$205.00 per share, implying a market cap of HK$14.545 billion; Qiming Venture Partners, an investor since the 2013 Series A, framed the IPO as a milestone in the commercialization of Chinese AI technology . Founded by CEO Huang Wei, with Liang Jia'en as co-founder, chairman and CTO, the company has since kept pushing into document intelligence — in early 2026 it released the Unisound U1-OCR foundation model, which it bills as opening an "OCR 3.0" era of business-level document understanding .
