Famous Quote
“Technology should help people access information, not restrict it.”
Why #60
Zhang built the first Chinese app to dominate globally. TikTok's 1.5B+ users and its AI recommendation engine have changed how the world consumes content. ByteDance is the most valuable private company in the world at $300B+.
The Story
Zhang Yiming founded ByteDance in 2012 and created TikTok, the first Chinese-built app to achieve global dominance — with 1.5B+ monthly active users, it is the most downloaded app in the world and has reshaped entertainment, commerce, music, and attention itself. TikTok's recommendation algorithm, powered by AI, is widely considered the most sophisticated content recommendation engine ever built.
Before TikTok, Zhang built Douyin (TikTok's Chinese counterpart, with 700M+ daily active users) and Toutiao (a news aggregation app that uses AI to personalize content). ByteDance's core innovation is treating content recommendation as an AI problem, not an editorial one — the algorithm learns what each user wants and delivers an endless, addictive stream of perfectly calibrated short videos.
Zhang is an engineer by temperament — quiet, data-obsessed, and allergic to politics. He stepped down as CEO of ByteDance in 2021 at age 38, citing a desire to work on long-term technology projects rather than manage a company navigating U.S.-China geopolitical tensions. TikTok's potential ban in the United States has made ByteDance the most geopolitically significant technology company in the world.

Frequently Asked Questions
Who are the greatest entrepreneurs of all time?
The greatest entrepreneurs include Steve Jobs (Apple), Elon Musk (Tesla/SpaceX), Jeff Bezos (Amazon), Bill Gates (Microsoft), and Mark Zuckerberg (Meta). Each built companies that fundamentally changed how the world works — from personal computing and smartphones to e-commerce, cloud computing, and social media.
What makes someone a successful entrepreneur?
Successful entrepreneurs share several traits: the ability to identify unmet needs, willingness to take calculated risks, relentless execution, and resilience in the face of failure. They combine vision with practical problem-solving and are willing to persist long after most people would quit. Capital and credentials matter far less than most people think — resourcefulness beats resources.
Can you become an entrepreneur without a business degree?
Absolutely. Many of the greatest entrepreneurs had no business education. Steve Jobs dropped out of college. Richard Branson left school at 16. Sara Blakely was selling fax machines. Henry Ford had no formal engineering training. Jack Ma was an English teacher. What matters is not the degree — it is the ability to see an opportunity, build something people want, and persist through failure.
