Company Overview

Duolingo took language learning, long sold as expensive boxed software, and rebuilt it as a free mobile game. From Pittsburgh, it now runs the largest consumer learning app by usage, with 58.7M daily active users in Q2 2026, and has grown into a profitable public company with more than $1B in annual revenue. The massively popular language-learning platform was founded at Carnegie Mellon University in 2011, aggressively utilizing intense gamification, an iconic green owl mascot, and massive data analytics to completely dominate the global education tech market.

Duolingo runs a freemium model. All core lessons are free, which builds a very large audience (133.1M MAUs in Q4 2025). The company then converts its most engaged learners into paying subscribers: Super Duolingo removes ads and gives unlimited hearts, while the higher-priced Duolingo Max adds AI features such as Video Call and Explain My Answer, and Family plans bundle up to six users. Subscriptions are the largest revenue line. Free users are monetized through ads, and Duolingo also sells the Duolingo English Test, an online proficiency exam used in university admissions, plus in-app purchases like streak repairs. Because most users arrive organically through word of mouth and social media, marketing spend stays relatively low, and app-store fees are a major cost of revenue.
