Stack gap

ICP companies with no detected tool in your category.

Why it works

A company that fits your profile but shows no tool in your category may still handle the work by hand or in spreadsheets. With no incumbent to replace, the conversation is about the problem instead of a switch. It works best when the company also shows the need, for example by hiring the team that would use your product.

How to act on it

Run a greenfield education play instead of a replacement play.
