C ai Wensheng is a prominent Chinese entrepreneur and angel investor, often referred to as one of the most successful 'domainers' in the world. A high school dropout from a poor farming family, Cai made his initial fortune by buying and selling internet domain names in the early 2000s, demonstrating an incredible foresight for valuable digital real estate. He is credited with registering and selling thousands of high-value domain names.

He leveraged this capital to become one of China's most influential angel investors, backing hundreds of startups. His most famous venture is Meitu, a company he founded that developed a hugely popular photo-editing app in China, allowing users to beautify their selfies with various filters and effects. Meitu went public on the Hong Kong Stock Exchange in 2016. Cai has since shifted his focus to blockchain and cryptocurrency, becoming a vocal and significant investor in the space.
