Question · Q4 2025
Mark Mahaney asked about potential reasons for DAU deceleration beyond law of large numbers and monetization focus, specifically market saturation and competitive intensity. He also sought updates on new data points reinforcing long-term growth opportunities and the expected timeline for product features like Speaking Adventures and advanced content for top nine languages to reach Duolingo Score 129.
Answer
Luis von Ahn (Co-Founder and CEO) dismissed concerns about market saturation and competition, citing 85% market share in language learning apps and low internet user penetration in key markets. He noted that churned users primarily stop learning rather than switching to competitors. Speaking Adventures is being tested and expected to scale mid-year for all users. More advanced content for the top nine languages, reaching Duolingo Score 129, is expected within a month or two, with continuous improvements throughout the year.
