Detailed narrative
User Growth and Retention Drivers
Duolingo's daily active users (DAUs) grew 23% year-over-year, accelerating from Q1, primarily driven by continuous product improvements through 'The Green Machine' and a successful 'Streak Revival' campaign that re-engaged over 15 million learners. User retention, measured by CURR, reached an all-time high, increasing by about a percentage point in the last year, indicating a stickier product experience across all regions and user types.
Monetization Strategy Evolution
The company is strategically evolving its monetization approach to align with user growth, moving away from friction-inducing methods. Key initiatives include extending free trials from 7 days to 1 month, which has significantly increased trial uptake and conversion to payers, while also improving DAUs by removing ads and energy limits for trial users.
AI Cost Efficiency and Product Development
Significant progress has been made in reducing the cost of AI features, particularly for 'video call,' which is now under $0.01 per call, down from $0.30. This reduction, primarily due to a shift towards open-source models, enables broader access to advanced features for Super subscribers and potentially all users, while also contributing to an increased full-year adjusted EBITDA outlook.
Experimentation with New Subscription Tiers
Duolingo is actively testing 'Super Lite,' an ad-supported tier priced at about half of Super, targeting users unlikely to purchase the full Super subscription. The company is also evaluating the future of its premium 'Max' tier, considering options like limited video calls for Super vs. unlimited for Max, or potentially sunsetting Max, with a decision expected in the next couple of quarters.
Marketing and Top-of-Funnel Expansion
The marketing team is expanding beyond organic word-of-mouth and social media, leveraging influencers in key international markets like China, Indonesia, and India, which contribute significantly to social media impressions. Performance marketing efforts have also become more sophisticated, leading to improved top-of-funnel growth across almost all regions, including a notable increase in the U.S.
Math and Music Product Strategy
For Math, the strategy has shifted to primarily target K-12 students who need to learn math, rather than attempting to engage the general adult population. While Math and Music currently have single-digit millions of DAUs and are smaller than Chess, they are expected to grow, with more details on the Music roadmap anticipated in the coming quarters⏳.
China Market Performance and AI Compliance
China is highlighted as Duolingo's second-largest market by DAUs, with expectations to become the largest within one to two years, and it monetizes comparably to France. Due to local regulations, all AI usage in China relies on Chinese models, not U.S. models, to ensure compliance with data residency and regulatory requirements.
