It is tempting to build for everyone. Your idea could serve twelve customer segments, you have identified six compelling use cases, and every conversation seems to unlock another market opportunity. The possibilities feel endless, and that is exactly the problem. Do not confuse possibility with priority. A multi-tool does a bunch of things, but none of them very well. It is also hard to describe who it is for and what it does. There are always exceptions, but early in the startup journey, when you are trying to build momentum, it is much easier to sell a scalpel to a surgeon than a Swiss Army Knife to everyone. Though it may seem counterintuitive, the narrower your initial focus, the easier it is to build traction and a strong foundation. Solve one specific problem for one specific audience really well, and you earn permission to expand. Build the scalpel before the Swiss Army Knife.
