A niche is a slice of the 8 billion people on this planet that you plan to serve.

A different way to think of it: a niche is a number.

“I serve gym owners making between $500k and $1M”.

According to Google, that’s 4,700 gyms in the world.

Do you plan to have 4,700 customers?

Most service businesses can’t literally serve all the customers in their niche.

Note that some outside that niche will be interested, too.
