WHAT IS IT?

Product-market fit means being in a good market with a product that can satisfy that market.

HOW TO USE IT?

Product-market fit is what makes or breaks a business. To achieve it you need to answer at least the following questions:

Pain: What problem does it solve?
Demonstrate: Can you create a prototype?
Quantifiable: Can you gather the numbers and support your idea?
Customer expectations: Can you solve customer’s problems and exceed expectations?
