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

Start with a slightly odd comparison.

Last month, the Bloomberg Billionaires Index updated, and ByteDance founder Zhang Yiming, with a net worth of $92.8 billion, overtook India’s Ambani to become the second-richest man in Asia — while sitting comfortably atop China’s own list. Counting from the $13 billion he was tracked at back in 2019, his wealth has grown more than sevenfold in six years. Meanwhile, a leaked ByteDance strategy document boiled down to a single headline: 160 billion yuan into AI in 2026. Its Doubao assistant has already crossed 300 million monthly actives.

The odd part is this: a man standing on the second tier of Asia’s wealth pyramid almost never gives an interview, stepped down as CEO back in 2021, and shows his face pitifully rarely. You can instantly picture Jobs on stage at a launch event, or every one of Musk’s posts on X — but you probably can’t recall what Zhang Yiming looks like, or what he said the last time he spoke in public.

How does an almost “invisible” man become the second-richest in Asia? The answer to that question hides in a single number.

When I had Claude score the 100 product managers who changed the world, Zhang Yiming came in at No. 5, overall OVR 96. But spread his six dimensions out and one number is glaring:

Vision 97 · Insight 95 · Taste 88 · Business 97 · Scale 98 · Originality 96 — overall 96. Taste 88 is the only one of the six that didn’t clear 90.

And here’s what I want to say: that lowest-in-the-room taste score isn’t his weakness — it’s precisely his sharpest weapon. This piece starts from that 88.

Originality 96: he didn’t build a product, he built a machine that mass-produces hits

Start with his most counterintuitive and most underrated dimension — originality.

Most people remember Zhang Yiming for Toutiao, Douyin, and TikTok. But if you see him only as “the man who made Douyin,” you’ve sold him short. Because before Douyin there was Toutiao; after Douyin there was TikTok, CapCut, Feishu, Fanqie Novel, and now Doubao — making one hit in a lifetime is luck; making hit after hit for ten years straight can’t possibly be luck. It can only be a repeatable method.

What Zhang Yiming truly originated isn’t any single app. It’s a machine that industrializes the act of “making a hit.” You’ve probably heard of the machine’s core parts: a recommendation algorithm so strong it borders on unnatural, taking “you might also like” to its absolute limit; a middle platform that lets new apps reuse capabilities that have already been proven, so a new one can sprout in a matter of months; a thoroughly data-driven culture where even the color of a single button is decided by A/B test, not by someone’s gut.

Before him, making a product was a “craft” — riding on the intuition and taste of one genius product manager. After him, making a product could be “industry” — riding on a system, a pile of data, an assembly line. That’s why ByteDance is called, inside and out, the “App Factory.” “Factory” is an insult when it’s applied to someone else; applied to Zhang Yiming, it’s his greatest achievement: he took something that used to depend heavily on individual genius and turned it into something you can mass-produce at scale.

No Chinese product person before him had truly made this road work. Originality 96 — no argument there.

Scale 98: he turned “dopamine” into a global business

Scale barely needs arguing.

Douyin plus TikTok add up to monthly actives in the billions — among the most frequently opened apps on the planet. ByteDance’s 2025 net profit reportedly reached $48 billion, averaging more than $660 million earned every single day. What matters more is that this scale is global — TikTok is one of the very few Chinese internet products to truly take root among mainstream users in the U.S., something not even Tencent or Alibaba managed.

But let me pause here and say something not so flattering. The hits this machine of his mass-produces run, overwhelmingly, on the same fuel: your attention, and that little bit of dopamine you find so hard to control. Douyin’s recommendation algorithm is strong not because it understands “what you need,” but because it understands, all too well, “what will keep you from stopping.” That’s the truth behind Scale 98 — the one we all quietly know and don’t much like saying out loud. And it leads straight into his next score.

Insight 95: he doesn’t see needs, he sees the weak spots in human nature

When we traditionally praise a product manager for “strong insight,” we mean they can see through to the real needs a user never voiced. Zhang Yiming’s insight is a different kind — colder, and more effective.

What he sees isn’t “what people want,” it’s “what people can’t help clicking.” The difference between those two is subtle but enormous. The former cares about your goals; the latter cares about your soft spots. One treats your intention to become better as its North Star; the other treats your instinct to get distracted, to be curious, to scroll one more, and one more, as fuel.

I don’t think that’s an insult. Seeing the weak spots of human nature this clearly — and engineering them into an algorithm — is itself top-tier insight, worth a 95. It’s only once you see clearly what this insight is aimed at that you understand why this list can only give him an 88 on the next dimension: taste.

Taste 88: it’s not that he has no taste — he deliberately gave it up

Now we reach the key to the whole piece.

What is taste? For Jobs, it was “this rounded corner is two pixels off and I simply cannot stand it.” For Zhang Xiaolong, it was “in ten years of WeChat, what I’m proudest of is what we didn’t build.” The core of taste is a person taking their own aesthetics and judgment and using them to decide, on the user’s behalf, “what is good” — even when the data doesn’t support it yet, I still believe this way is more right.

And Zhang Yiming is precisely the man who deliberately deletes that “I believe.”

He has a widely circulated line, roughly: don’t use your value judgment to make choices for users — let the data speak. It’s an extremely clear-eyed and extremely effective product philosophy — it freed ByteDance from the randomness of “the boss decides on a whim,” made every decision traceable, optimizable, scalable. Behind every Douyin redesign, every recommendation, isn’t one person’s taste — it’s the result of tens of millions of A/B tests.

But turn that line around and listen again: the flip side of “let the data speak” is “I won’t judge what’s good for you.” Data only tells you “which one the user clicked,” never “which one is better for the user.” It can tell you “the button that gets you to scroll ten more minutes of short video is easier to click,” but it will never answer, on your behalf, “whether those ten extra minutes were good or bad for this person.” Only taste can answer that question — and in Zhang Yiming’s system, that question is precisely the one switched off.

So Taste 88 doesn’t mean his aesthetics are poor or his ability lacking. It means this machine of his is designed, from the root, not to aim at “is it good” but only at “do you love watching it.” He didn’t lose on taste — he simply never put taste into the machine. That’s his strongest point, and it’s exactly why this list can only give him an 88. A man who hands “what is good” over to the data will, on a dimension that measures “how much you held the line on good for your users,” necessarily fall short of full marks.

Set them side by side and it’s clearer still: Jobs’s products are extensions of his taste; Zhang Yiming’s products are what the data grows into on its own, once he’s deliberately pulled taste out. On this list, the two men sit at opposite poles of product philosophy.

Two men named Zhang: one wants you to leave, one wants you to stay

And there’s a contrast on this list that cuts deeper than Jobs, because he too is Chinese, and he too ranks above Zhang Yiming — No. 2, Zhang Xiaolong.

Zhang Xiaolong has a line quoted countless times: “A good product should let the user use it and leave.” In ten years of WeChat, what he’s proudest of is “what we didn’t build” — no splash-screen ads, no read receipts, no piling on a bunch of things you didn’t want while you’re mid-chat. His entire product philosophy is shielding users from the designs that would pull them into addiction while doing them no good.

Zhang Yiming’s machine does almost the opposite: by every possible means, keep you from leaving, get you to stay a little longer, get you to scroll one more. Every “next video autoplays” and “infinite feed of things you might like” on Douyin optimizes the same metric — user time on app. Use it and leave? That’s the last thing Douyin wants to see.

I have no intention of ruling one above the other here. Both made products that changed the daily lives of a billion people; both sit firmly in this list’s top five. I only want you to see this astonishing fact: the question of “what makes a good product” got completely opposite answers from two Chinese product managers who both reached the very top. One holds that a good product “lets you leave and doesn’t waste your time”; the other holds that a good product is “impossible to put down, one more second is one more second gained.” And the market, at a scale of a billion, rewarded them both at once.

That’s also why, on taste, Zhang Xiaolong scores higher and Zhang Yiming lands at 88 — not a gap in ability, but the fact that the two of them stand at opposite ends on “whether to hold the line for the user.” Zhang Xiaolong chose to hold, so there are things his products refuse to do; Zhang Yiming chose to let go, handing the judgment entirely to the data and to human nature, so his machine runs faster than anyone’s — and cares less than anyone’s about whether you feel empty or fulfilled after you’ve scrolled.

Vision 97 and Business 97: an “invisible” man in actual control

Two dimensions left, quickly.

Business 97 needs little explanation — turning attention into advertising, e-commerce, short dramas, and AI across the board, building a money printer that earns $660 million a day. Commercially, he’s nearly flawless.

On Vision 97 I want to flag an easily overlooked detail: Zhang Yiming stepped down as CEO back in 2021, saying publicly he’d shift to “long-term strategy and company culture.” Many took this as retirement. But look at the equity structure and you’ll see he holds more than 60% of ByteDance’s voting rights — he’s the real party in control. He didn’t leave the table; he went from “the man playing each hand” to “the man setting the table’s rules.” A person who, at the peak of his career, deliberately retreats from the spotlight into the wings while keeping a firm grip on the final decision — that clarity about “where I ought to sit” is itself a form of vision.

That machine is now being retested by Doubao

Writing this far, the question from the opening — “how does an invisible man become the second-richest in Asia” — has a clear answer: because what he built isn’t a product that needs him on stage, it’s a machine that needs no appearance from him and keeps mass-producing hits on its own. The more quietly the machine runs, the more invisible he can be.

But now that machine faces its biggest test yet: AI.

ByteDance plans to pour 160 billion yuan into AI in 2026, with Doubao’s monthly actives charging to 300 million. On the surface, this is just the “App Factory” mass-producing its next hit. But AI has one fundamental difference from short video: the winning move in short video is “who understands better how to keep you from stopping,” while the winning move in AI is likely “who understands better what the right answer is” — and the latter is exactly what needs taste and judgment, precisely the thing his machine deliberately pulled out years ago.

So Zhang Yiming’s real bet isn’t whether Doubao can stack up another 300 million monthly actives — with his machine, that’s not hard. The real question is: can a machine designed to “not judge good from bad, only chase what you love watching” do well at something that “must judge good from bad”? Can a man who left his taste at 88 make up those 12 points on a new track that rewards taste?

That answer will emerge slowly as this 160 billion goes in during 2026. I don’t have it yet either — but I do know that this time, “let the data speak,” on its own, may not be enough.
