The CEO Diary with Fexingo · 2026-07-11 · 13 min
Episode 108 of The CEO Diary: How Duolingo CEO Luis von Ahn built a language-learning app that's worth over $7 billion despite giving away its core product for free. Lucas breaks down the freemium model that actually works - how Duolingo converted 8 million daily active users into 6.6 million paying subscribers without alienating the free tier. Luna asks whether the gamification strategy is sustainable as competition heats up. They examine the psychology behind streak freezes, the role of AI in lesson personalization, and why Duolingo's mascot Green Owl is worth $100 million alone. Plus: how the company's IPO in 2021 changed its calculus, and what the next billion users might look like. A focused look at one of the most valuable edtech companies built on a platform that's still free for most. #Duolingo #LuisVonAhn #FreemiumModel #Gamification #EdTech #LanguageLearning #MobileApps #UserRetention #MonetizationStrategy #AIInEducation #IPO #SubscriptionModel #DAU #GreenOwl #BusinessGrowth #Business #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
