Product-Market Fit Pyramid, breaks product-market fit down into five key components: your target customer, your customer's underserved needs, your value proposition, your feature set, and your user experience (UX).

A product is a specific offering intended to meet a set of customer needs.

Viewing product-market fit in light of this model, it is the measure of how well your product (the top three layers of the pyramid) satisfies the market (the bottom two layers of the pyramid).
