Inspiration
Managing subscriptions has become a challenge in today’s digital-first world. Most people don’t know how much they’re spending, forget renewal dates, or struggle to pick the right plans. We were inspired to solve this problem by combining AI personalization with RevenueCat’s subscription management tools to create a smarter, user-first solution.
