Kuaishou co-founder who democratized algorithms to empower ordinary people in lower-tier markets as content creators
Su Hua (born 1985) is the co-founder and CEO of Kuaishou Technology, a Tsinghua University computer science graduate who previously worked as an engineer at Google China. In 2011, he co-founded Kuaishou (originally GIF Kuaishou) with Cheng Yixiao, transforming it from a GIF creation tool into a short video social platform. Su Hua's core philosophy is algorithm democratization — unlike Douyin's centralized traffic distribution, Kuaishou's algorithm is dedicated to giving every ordinary user a fair chance at exposure, rather than concentrating traffic among a few top creators. This philosophy gave Kuaishou a deep user base in lower-tier markets (third, fourth, and fifth-tier cities and rural areas), making it one of China's largest short video platforms. Kuaishou went public on the Hong Kong Stock Exchange in 2021, with a market cap that once exceeded $170 billion.
Traditional recommendation algorithms tend to concentrate traffic on already-successful creators, creating a Matthew effect. Su Hua believes algorithms should give everyone a fair chance, including farmers, craftspeople, and ordinary workers in third and fourth-tier cities. Kuaishou's algorithm design principle: even creators with very few followers should have the chance to be seen by strangers.

Kuaishou's mission is to record and spread the world's diverse lifestyles. Not just the refined lives of urban white-collar workers, but also rural sunrises and sunsets, factory workers' labor, and ethnic minority traditional cultures. Su Hua believes these lives ignored by mainstream media are equally valuable and equally deserving of being recorded and shared.

Su Hua believes good technology can help people build genuine community connections, not just consume content. Many Kuaishou users are not just viewers but genuine community members who participate in interactions. The value of technology lies in lowering the barriers to human connection, not creating false prosperity.

China's early internet development mainly served the urban middle class, ignoring hundreds of millions of lower-tier market users. Su Hua believes truly valuable internet platforms should benefit everyone — whether through content creation income or access to better products through e-commerce. Kuaishou's inclusive philosophy is the core of its business model.

Distribute traffic to long-tail creators rather than concentrating it at the top, creating a healthier content ecosystem
Early Kuaishou data showed that the top 1% of videos by views received only about 30% of total views, with the remaining 70% distributed among a large number of ordinary creators. This contrasts sharply with Douyin's top-heavy model and is the fundamental reason Kuaishou gained deep user loyalty in lower-tier markets.
Kuaishou prioritizes showing content from people users follow over algorithmically guessed interest content, reinforcing genuine social relationships
Kuaishou's dual-column feed design (distinct from Douyin's single-column immersive feed) allows users to see multiple video thumbnails simultaneously, actively choosing what to watch rather than passively accepting algorithm pushes. This design reinforces user agency and social relationships rather than pure content consumption.
While competitors focused on first and second-tier cities, be the first to deeply cultivate third, fourth, and fifth-tier cities and rural areas, building an irreplicable user base
Between 2016-2018, while Douyin and Weibo short video focused on first and second-tier city young users, Kuaishou had already established a deep user base in third, fourth, and fifth-tier cities and rural areas. These users had extremely high loyalty because Kuaishou was the first content platform truly designed for them. When Douyin later tried to enter lower-tier markets, Kuaishou's first-mover advantage had created a moat.
Kuaishou uses complex algorithms to achieve decentralized traffic distribution, using technical means to combat technology's own Matthew effect. This is a paradox — using algorithms to reduce algorithms' favoritism toward top creators.
Kuaishou's inclusive philosophy attracted a large lower-tier market user base, but these users' commercial value (advertising revenue, e-commerce conversion) is relatively lower, causing Kuaishou to lag behind Douyin in commercialization efficiency for a long time. How to balance the inclusive philosophy with commercial sustainability is an ongoing challenge for Su Hua.
2007-2011
Working as engineer at Google China, accumulating technical capabilities and deep understanding of recommendation algorithms
After graduating from Tsinghua University's computer science department, Su Hua joined Google China, working on search and recommendation algorithm teams. This experience gave him a deep understanding of algorithms' enormous influence on information distribution, laying the technical foundation for his later design of Kuaishou's decentralized algorithm.
