Content: The only thing that matters is getting to product/market fit." Marc Andreessen defined the term as follows: “ Product/market fit means being in a good market with a product that can satisfy that market.” Many people interpret product/market fit as creating a so called minimum viable product that addresses and solves a problem or need that exists. Steve Blank referred to the concept of product/market fit as a step in between customer validation (step #2 in his book The Four Steps to the Epiphany) and customer creation (step #3). Interpretations
Product/market fit might be interpreted in terms of Alexander Osterwalder 's Business Model Canvas paradigm as comprising value proposition, customer segment, relationship, and channel. Achieving Product/market fit implies these are set without requiring additional changes or pivots. Popular metrics
The 40% rule
One metric for product/market fit is if at least 40% percent of surveyed customers indicate that they would be "very disappointed" if they no longer have access to a particular product or service. Alternatively, it could be measured by having at least 40% of surveyed customers considering the product or service as "must have". Sean Ellis is noted for popularizing this heuristic after examining many startups.
