From Translation Service to Freemium Model
At first, Duolingo made money by translating content for others. But as it grew, it needed new ways to make money. This led to the freemium model.
This new model offers free and paid versions. The paid options, like Duolingo Plus and Duolingo Max, bring in a lot of money.
Revenue Streams and Monetization Strategy

This wide range of languages meets the varied interests and needs of learners around the world.
Duolingo’s approach to creating courses has changed over time. At first, it relied on volunteers to add new languages. But as it grew, it started using professional linguists. This ensures courses meet CEFR standards, offering a better learning experience.
