Growth.Design Case Studies

Growth.Design Freemium Beginner

Interactive comic style teardowns of real products like Airbnb, Duolingo, and Spotify that show UX and psychology principles in action, not in the abstract. It is the fastest way to train your eye for why a flow works or fails. Great for founders who learn by seeing concrete examples.

  • See heuristics and psychology applied to products you actually use
  • Small friction points compound into big drop offs
  • Design choices are testable bets, not matters of taste
