Build Better Paywalls with AI
Steve P. Young hosts Trent Hommeyer of Helium, an AI paywall builder and experimentation platform. Trent shows a Flappy Bird paywall (higher score = deeper discount, up to 50%) that won an experiment for a student AI app, argues for attention-grabbing animation, age-based segmentation, and 'who referred you?' authority cues for older users, and says app-to-web checkout via Apple Pay/Stripe now beats in-app purchase on trial-to-paid and retention. Ends with a live AI paywall build and two short app audits.
