The product adoption curve is a visual representation of when different customer segments are most likely to adopt your software. It consists of five stages: Innovators, Early Adopters, Early Majority, Late Majority, and Laggards. Each segment represents a distinct group of customers with varying levels of willingness to try new products or technologies. Understanding these segments can help businesses tailor their product messaging and marketing strategies to increase user adoption rates and sustain growth throughout the entire adoption curve. By leveraging in-product experiences and feedback, companies can optimize their product offerings and improve customer satisfaction across all stages of the product lifecycle.
