The AI Growth Playbook for Subscription Apps – Phil Carter, Elemental Growth
Phil Carter walks through twelve AI-era tips organized by his subscription value loop (value creation, delivery and capture), covering onboarding, personalization, creative testing, tiering and credits. He backs them with client results such as Runna going from tens to 400+ creative concepts a month and a 75% LTV lift from a multi-step freemium paywall.
