Duolingo, Inc. (DUOL)

Executive Summary

Duolingo is the world’s largest language-learning platform — approximately 110 million monthly active users learning Spanish, English, French, German, Mandarin, Japanese, and dozens of other languages through the company’s gamified freemium app. The 2024 launch of Duolingo Max (AI-powered premium tier with conversational practice using GPT-4 and the company’s own model) was the most consequential product expansion. The stock has corrected 79 percent over the past twelve months — among the deepest drawdowns in U.S. consumer internet — from the late-2024 peak around $530.
