How specific should my ideal customer be for a consumer app versus a B2B tool?
The short answer
For B2B you can and should get specific by role, company size, and trigger event because a handful of accounts can matter, while consumer needs a sharp psychographic and a clear use-moment more than firmographics. In consumer, "25 to 35 in metros" is useless, but "people who commute alone and hate silence" is a real target. Both need specificity, they just specify different things: B2B by who and where, consumer by when and why. Pick the axis that predicts who actually opens their wallet, and refine it from real early users.

Why we picked it
Zhuo ran product design at Facebook, so she has actually shipped consumer products at billion-user scale, and here she is candid that you define a consumer user by watching how they behave and what moment they are in, not by an age bracket. It is a good starting point for seeing why a consumer ideal customer hinges on use-moments and motivation rather than clean demographic buckets. Treat it as a way of thinking, then pressure-test it against your own users.
Consumer products live or die on understanding real behavior and context, so ground your user in what they are trying to do, not just who they are on paper.
She stresses going out and watching actual users (including outside your own city or country), which is a healthy nudge for Indian founders whose users may not look like the founder.
Design decisions should trace back to a specific user need, so a fuzzy demographic label is not enough to build on.
Why we picked it
This piece lays the B2B and B2C cases side by side so you can see that the axis of specificity is genuinely different: B2B narrows on who decides, what risk they carry, and how much proof they need, while B2C narrows on the individual moment and low-friction relevance. That contrast is exactly what a founder needs to pick the right kind of precise, rather than copying a template from the wrong side. Use it as a lens, not a rulebook.

The definitive framework for building products people return to without paid nudges, the Hook Model, backed by a million-plus copies sold and used across top consumer products.
