Business Model
What each company does and how it makes money
Zhihu operates China's leading question-and-answer platform where users share knowledge and expertise across diverse topics. It generates revenue primarily through online advertising (~60% of sales) and paid membership services, supplemented by content-commerce solutions and vocational training. Its competitive moat stems from its massive, high-quality user-generated content library and strong network effects that reinforce its position as China's go-to knowledge-sharing community.
Alphabet is a technology conglomerate best known for its Google search engine and digital ecosystem. It generates over 80% of its revenue from digital advertising—primarily through Google Search, YouTube, and its ad network—with the remainder coming from Google Cloud services and other ventures. Its dominant competitive advantage lies in its massive user data network, which creates powerful network effects and makes its advertising targeting capabilities nearly impossible for competitors to replicate at scale.
