HEAD OF THE DAY

🇨🇳 Zhang Yiming

🤖 From Outsider Engineer to TikTok Mastermind: Zhang Yiming founded ByteDance in 2012, launched the AI‐driven news app Toutiao and the global hit Douyin (TikTok), and by 2025 has amassed an estimated $65.5 billion fortune—making him China’s richest person. Born in Longyan, Fujian in 1983 and a Nankai University computer-engineering graduate, he cut his teeth at startups and Microsoft before persuading skeptical VCs to back his recommendation-engine vision. He stepped down as CEO in 2021 but still wields over 50 % of ByteDance’s voting rights.

Fun Fact: To stay close to his product, Zhang banned senior managers from calling him “boss” and once made them post their own TikToks—doing push-ups if their videos didn’t hit a target number of likes.

👉 Lesson learned: Pair deep technical chops with relentless user-obsession—use data and AI not just to build models, but to shape culture and products that stick.
