Duolingo’s Growth Model: A framework for understanding, exploration, and forecasting

Duolingo's evolution has required us to have a more fine-grained understanding of the levers that drive user growth. Our Growth Model is a framework that allows us to better characterize our topline DAU and MAU metrics and model how they change over time. Using this framework, we have identified new strategies to unlock user growth, built a robust forecasting engine, and explored new opportunities for product development.
