Between Q1 2020 and Q4 2024, Duolingo's performance metrics illustrate a compelling growth narrative. Starting with 38 million monthly active users and 8.5 million daily users in early 2020, the platform witnessed rapid growth, reaching 117 million monthly active users and 40.5 million daily active users by the end of 2024.
Most strikingly, the paid subscriber count surged from a modest 900,000 subscribers to 9.5 million subscribers, an explosion of almost 1,000%, underscoring a robust conversion strategy. This remarkable acceleration, particularly visible from early 2023, not only signifies a broadening user base but also highlights Duolingo's effective monetisation.
Adding to this success is their engaging notification reminder style, which consistently nudges users to maintain daily learning streaks, fostering deeper engagement and loyalty that drive sustained growth.
