“At the core of PMF is the idea that you are producing something novel in some business and/or technical aspect, NOT that your are selling a product or service that already exists and PMF is there. For example, if you want to compete with Salesforce you already know there is a PMF, it is a CRM!”
PMF is not about building something novel. It is about ensuring your product solves a real and critical problem for your target segment. Only customers are the experts on their problems and priorities. Entrepreneurs are experts on solving problems but we too often solve the wrong problems in elaborate ways.
Salespeople buy Salesforce today because everyone else buys Salesforce. CRMs come in all shapes and sizes. To find PMF for your CRM you need to niche down to find a segment that is underserved by Salesforce.
You can only do this by doing actual discovery interviews with prospects in an unbiased way where you explore their experience around specific problem areas without ever mentioning your brilliant solution - as proposing a specific solution is likely to bias your subject. This is hard for founders as we tend to fall in love with our ideas and often slip into pitch mode mid-interview. This is a fundamental mistake.
