Clear Water Bay Startup Fund
清水湾基金
Clear Water Bay Startup Fund (清水湾基金) is the investment fund of Professor Zexiang Li — the Hong Kong University of Science and Technology professor best known in this corpus as an early backer of DJI . Elsewhere's corpus doesn't carry a standalone profile of the fund itself; what it shows is its deal activity, which clusters around hard-tech and robotics startups. It backed robot-vacuum maker Cloud Whale in a Pre-A round alongside Mingshi Capital in 2017 and stayed in through the company's later rounds ; it repeatedly doubled down on digital food-tech company BOTINKIT across three consecutive rounds through mid-2024 ; and more recently it co-invested in LUDENS AI's angel+ round (April 2026) and sits on the cap table of Tarran, a robotics-style vehicle startup, alongside Shunwei and Sequoia .
