Executive summary

Duolingo Q4 FY25 — Strategic Shift to User Growth and AI Investment

Duolingo is undertaking a strategic shift in 2026, prioritizing user growth and AI innovation over short-term monetization, aiming to redefine learning and capture a massive market opportunity. This involves significant investments in product improvements, free user experience, and new subjects like math and chess, which will lead to slower bookings growth and lower profitability in the near term. The company targets 100 million DAUs by 2028, believing this foundational year will unlock substantial long-term value.

Core to the strategic shift and long-term value creation, indicating the effectiveness of current investments.

We now expect DAU growth to be about 20% year-over-year throughout 2026. This reinforced my conviction that we needed to take more decisive actions to reaccelerate DAU growth.

Q&A highlights

Why now for the strategic shift, given AI advancements, and what are the 1-2 key product priorities to reach 100M DAUs by 2028?

Luis explained AI allows for significantly better teaching and will change learning, creating a massive opportunity. Top priorities are teaching languages better, improving the free user experience (less friction), and investing in new subjects like math, music, and chess, with chess already at 7M DAUs.

“AI is going to allow us to teach significantly better. And I also believe that the way people learn is just going to change.”

Detailed narrative

Strategic Shift to User Growth

Luis von Ahn emphasized a strategic shift for 2026, prioritizing the growth of the active learner base (the 'size of the pie') over immediate monetization. This decision is driven by the deceleration of DAU growth throughout 2025 and into 2026, and a strong conviction in the transformative potential of AI in education. The company aims to reach 100 million daily active users by 2028, believing this will create a more resilient brand and a significantly larger business.

AI as a Core Enabler

AI is seen as a fundamental game-changer, enabling Duolingo to teach significantly better by personalizing learning, addressing user difficulties, and improving conversational practice. The company plans to leverage AI to offer a one-on-one tutor quality experience that is as engaging as a mobile game. This includes features like 'video call with Lily' and developing Duolingo Math to be the 'best tutor app for math,' targeting a global market of 1 billion math learners.

Investment Areas for DAU Growth

The plan for 2026 focuses on three main categories: teaching languages better, improving the free user experience by reducing friction, and investing in new growth engines like math, music, and chess. Chess has already achieved 7 million daily active users in less than a year, demonstrating the potential of new subjects. These investments are expected to drive DAU acceleration towards the 2028 target.

Monetization Philosophy Evolution

Management acknowledged that past monetization efforts, while effective, sometimes involved adding friction that hindered DAU growth. The company is now exploring alternative monetization strategies, such as adding more valuable features and in-app purchases (e.g., avatar customizations), that do not rely on friction. While these methods may be slower to implement, the goal is to increase the payer base beyond the current ~10% of monthly active users without compromising user growth.

Product Roadmap and Advanced Content

Key product initiatives include 'speaking adventures,' a game-like feature integrating speaking practice, expected to roll out mid-year for all users. Additionally, more advanced content for the top 9 languages, covering over 90% of DAUs, will be available in a month or two, reaching a Duolingo score of 129, which is relevant for knowledge jobs. These are expected to enhance learning and engagement and will be continuously improved throughout the year.

Market Opportunity and Competition

Management expressed no concerns about market saturation, citing low penetration rates (e.g., 2% of US internet users daily use Duolingo) and significant growth potential even if all countries reached US penetration levels. Competition is also not a major concern, as Duolingo holds an 85% market share in language learning apps, and new entrants struggle to compete with its free product and large distribution without resorting to paywalls that limit their scale.
