Everyone wants to build something for everyone. It is a reasonable impulse. The problem is that "everyone" is not a person, does not have a specific problem, and cannot tell their friends about you in a way that matters.
I have spent decades watching this mistake repeat. The more you try to be for everyone, the less you are for anyone.
The question is not "how do I reach more people?" The question is "what is the smallest group of people who would be genuinely upset if what I built disappeared?"
That group is your minimum viable audience. Not your total addressable market. Not your ICP slide deck persona. The smallest specific group of human beings who would actually miss you.
Here is the counterintuitive truth: the smaller and more specific that group, the more likely they are to talk about you. They talk because what you made is unmistakably for them. It reflects their worldview. It solves a problem they thought no one else noticed.
Mass media trained us to think scale comes from reaching everyone at once. It does not. Scale comes from the first hundred people telling the next hundred, and so on. But that only works if the first hundred care enough to bother. And they only care enough to bother if you made something that felt like it was made specifically for them.
When you try to appeal to everyone, you sand off every edge that would have made someone say "this is exactly for me." You end up with something inoffensive and forgettable. Nothing that gets talked about, because there is nothing specific enough to share.
The smallest viable audience also holds you accountable. You cannot hide behind vague brand claims when the people you serve are specific enough to notice when you stop delivering. They will tell you. And they will tell others.
If you are building right now, here is the concrete version. Your first ten customers are your minimum viable audience. Not a demographic. Not a segment. Ten specific people with a specific problem in a specific moment.
The question to answer before anything else is not "what do I build?" It is "who is this for, and what changes for them when it works?"
If you cannot answer that in one sentence about a real person, you do not have an audience yet. You have a market hypothesis.
Do not run ads until you can answer it. Do not write content until you can answer it. Find the smallest group of people who would be genuinely upset if you shut down. Serve them so well that they have no choice but to tell people like them.
That is how you get to the next hundred.
Before you try to reach everyone, ask the harder question. Who are the ten people who need this the most?
Start there. It is the only place worth starting.
