Ehsan's Insight
Nir Eyal's Hook Model (Trigger → Action → Variable Reward → Investment) explains why some products are habit-forming and others are not. The most underappreciated element is Investment — the step where the user puts something into the product (data, content, preferences, connections) that makes the next cycle more valuable. Every file uploaded to Dropbox is an investment. Every connection made on LinkedIn is an investment. Every playlist created on Spotify is an investment. Without the investment step, the product relies entirely on triggers and rewards to drive return usage. With investment, the product gets stickier with each use because switching away means abandoning accumulated value. When designing retention mechanics, focus on the investment step. It is the compound interest of product design.
