Full Analysis
Duolingo reported a strongly positive Q3 earnings call with results exceeding expectations across bookings, revenue, and profitability. Daily active users (DAU) surged 29% year over year, accelerating in eight of its ten largest countries, driven by product improvements like the Green Machine optimization system and strategic partnerships with Brawl Stars and Eggy Party that foster strong user retention. The company highlighted significant monetization progress, including a major milestone for its Chess product reaching 10 million DAU and substantial cost reductions in AI features. Duolingo successfully moved its Video Call feature from the Max tier to Super, expanding access tenfold while lowering costs via open-source models. Management noted that while paid-subscriber growth has slowed, it expects this metric to bottom out soon as revenue growth rebuilds. Looking ahead, Duolingo provided Q4 guidance for approximately $84 million in adjusted EBITDA with a 26.1% margin, projecting 13% bookings growth and 14% revenue growth. The company plans to transition individual Max subscribers to Super Family pricing and continues investing in advertising operations which are showing improving growth. Despite rising operating expenses due to bonuses and investments, the firm maintains strong profitability and aims to reach 1 billion global learners.
