Godin frames strategy as four choices: your customers, your competition, your source of validation, and your distribution. His claim is that product people gloss over all four, inherit them by default, then wonder why the roadmap reads like someone else wrote it. The first choice carries the other three. Name who this is for and you have also named who you get compared to, whose taste you are matching, and where the thing has to be sold.
The smallest viable audience inverts the reflex question. Not how many people can we reach, but what is the fewest we can serve so completely that they would notice if we stopped. Answer that and the group stops being a marketing target and starts behaving like a spec: what they can afford, what they already believe, how technical they are, how patient they are, each now a product constraint rather than a research slide.
Godin reads the spec out loud:
His failure case is a product that dressed for one audience and shipped to another. The Humane pin arrived looking like a finished, Apple-quality device, and was pre-ordered by exactly the people who buy finished, Apple-quality devices. When what shipped was not that, the verdict was already written. Put the same rough build in front of four hundred Product Hunt tinkerers who like Raspberry Pi and want to wonk with it, and nothing about the object has changed, only the audience. That is the argument: the audience decides what counts as good.
