Middle Coast Investing LLC Daniel Shvartsman | “Duolingo shares have corrected due to a temporary growth slowdown from business model recalibration and fears that AI translation will render language learning obsolete. The manager believes these concerns misinterpret the intrinsic self-development motivation of users, presenting a highly attractive entry point for a deeply engaging platform.” | BULL | Q1 2026 Apr 10, 2026 | View Pitch |
Infuse Partners Ryan Reeves | “We shared our initial thesis last quarter but the price has only plummeted. Essentially, there is a short term and a long term risk but I believe they are being conflated. The short term risk is that” | BULL | Q1 2026 Apr 9, 2026 | View Pitch |
Spyglass Capital Management Portfolio Manager | “Shares dropped because of investor concerns over management's shift towards prioritizing user expansion over short-term earnings. However, double-digit paid subscriber growth and potential AI integration highlight favorable long-term prospects.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Infuse Partners Ryan Reeves | “To end, we'll talk about a new holding. I have followed the company closely since the IPO since my wife was an avid user, not wanting to “break her streak” in learning Italian. I thought growth would drop off a cliff after COVID as happened with many other companies, and yet, quarter after quarter the company continued to execute. In fact, there are only four companies I can find that have grown revenues greater than 30% for at least the last 20 quarters in a row – MercadoLibre, Axon, Hims, and Duolingo. The stock was down almost 70% after the valuation got far too rich and management made it very clear they were prioritizing learning over monetization for 2026. Duolingo shouldn't be thought of as a language learning app, it's an engagement machine that happens to educate. Almost 40% of monthly users log into the app every day. As the company broadens its education subjects like math, music, chess, and other areas, retention should increase even more. AI will allow the company to create better content and accelerate the platform's expansion. We paid ~18x FCF, inclusive of stock-based comp. BSD Analysis: Duolingo's moat is brand, engagement, and habit formation at massive scale. The product converts learning into a daily behavior, which is rare in education. Monetization is improving, but pricing power has limits. Content is defensible through data and iteration, not IP. The failure mode is engagement decay as novelty fades. Competition is abundant, but few achieve Duolingo's retention. The bull case is expanding into broader education verticals. Duolingo is a consumer app masquerading as edtech.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Baron Focused Growth Fund David Baron, Ron Baron | “Duolingo, Inc. is the world's leading language-learning app, with over 135 million monthly active users. The company is known for its effective gamification strategy and high engagement. Shares declined during the quarter after the company guided to lower-than-expected bookings as it prioritized user experience. Although bookings and user growth appear unlikely to decelerate meaningfully from current levels, uncertainty around engagement metrics and the pace of monetization led us to exit the position and reallocate capital to other investment opportunities. BSD Analysis: Duolingo enters 2026 as the world's leading edtech platform, successfully weathering a 2025 valuation reset to trade at a more attractive 23x forward P/E. The company continues to deliver exceptional user metrics, with daily active users (DAUs) up 36% year-over-year to over 50 million as its gamified ecosystem remains unmatched. For 2026, the investment case is anchored by 23% projected revenue growth and a push toward a 31% adjusted EBITDA margin as monetization efforts in China and the "Duolingo Max" AI tier take hold. While concerns regarding OpenAI's competition initially pressured the stock, Duolingo's structured pedagogical moat and real educational outcomes have proven far stickier than simple chatbots. Management is successfully leveraging AI to lower content creation costs while increasing the pace of its course rollouts. Financial analysts have recently revised revenue estimates upward, viewing the recent market dip as a rare buying opportunity for long-term growth. For 2026, Duolingo remains a premier "Rule of 40" profitable growth company with a massive underpenetrated market.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Sands Capital Technology Innovators Fund Michael Clarke, Thomas Trentman | “Duolingo holds over 90% share of active users in online language learning and serves an estimated $100 billion addressable market. AI-powered conversational features target professional English learners—75% of the market but underrepresented in its paying base. Sands expects these features to drive higher conversion and monetization. :contentReference[oaicite:4]{index=4} BSD Analysis: DUOL's gamified learning model and AI conversational upgrades expand TAM and improve unit economics. Subscription growth visibility and operating leverage remain strong.” | BULL | Q3 2025 Sep 30, 2025 | View Pitch |
Spyglass Capital Management Portfolio Manager | “Following a sharp share price pullback, the manager re-established a position in Duolingo, believing the market underestimates the company's long-term unit economics and subscription growth. The business remains highly attractive due to low global market penetration and rapid customer adoption of its high-tier Duolingo Max service.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
Pernas Research Deiya Pernas | “The manager missed an investment opportunity in Duolingo by prematurely writing it off as a structural loser to emerging AI technologies. They overlooked how its gamified model, robust curriculum, and user engagement protect its moat. Ultimately, Duolingo leveraged AI as an enhancement tool rather than facing disruption, leading to a 90% share price appreciation since their initial review.” | BULL | Q4 2024 Jan 24, 2025 | View Pitch |
