100 Products That Changed the World · #14: Douyin / TikTok

In July 2026, time spent per user on Douyin passed WeChat for the first time. Ten years earlier it was a 15-second music video app called A.me. The decision it got right: open the app and the feed is already playing, no need to follow anyone first. Douyin / TikTok ranks #14 with an overall score of 92.85; scale, at 96, is its highest dimension and durability, at 88, its lowest.

The 100 PMs Who Changed the World · No. 5 | Zhang Yiming: His Best Product Isn't Douyin — It's a Machine That Mass-Produces Hits

No. 5 on the list is Zhang Yiming, OVR 96. Just last month, his net worth of $92.8 billion overtook Ambani, making him the second-richest man in Asia and the undisputed richest in China — and this is a man who almost never gives interviews, stepped down as CEO back in 2021, and rarely even shows his face. How does an "invisible" man become the second-richest in Asia? The answer hides in the lowest of his six dimensions: Taste, just 88. That's not a knock on him — it's precisely the key to understanding him. Because Zhang Yiming is the most counterintuitive product manager on this list: he deliberately refuses taste, replacing intuition with data and aesthetics with algorithms, and built a machine that keeps mass-producing global hits. This piece breaks down his six scores — and a bet that Doubao is now putting back to the test.
