What this episode covers

Lucas and Luna dive into Duolingo's unconventional playbook: how a small startup used gamification, a relentless A/B testing culture, and a controversial AI pivot to build one of the most popular education apps in the world. They break down the numbers behind the green owl's 500 million users, the psychology of streaks and notifications, and why CEO Luis von Ahn calls their user retention strategy 'a slot machine for learning.' Plus, a look at how Duolingo is now leveraging generative AI to create lessons faster and personalise the experience. If you've ever wondered how a free app gets people to study a language every day, this episode explains the mechanics. #Duolingo #LuisVonAhn #Gamification #LanguageLearning #EdTech #UserRetention #ABTesting #Freemium #AI #MobileApps #StartupGrowth #BehavioralEconomics #GreenOwl #Learning #Business #FexingoBusiness #BusinessPodcast #StartupStories Keep every episode free: buymeacoffee.com/fexingo
