BYJU'S vs Duolingo, Inc.: Strategic Comparison

This in-depth comparison examines BYJU'S and Duolingo, Inc. across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching BYJU'S on its own, evaluating Duolingo, Inc., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between BYJU'S and Duolingo, Inc. is widest.

On the headline numbers, annual revenue is ~$614.6M (FY2022) for BYJU'S and $1.0B (FY2025) for Duolingo, Inc., while their respective market capitalizations stand at N/A and $6.6B. BYJU'S is headquartered in India and Duolingo, Inc. in United States, and those different home markets shape how each company competes.

BYJU'S: BYJU'S is the best-known rise and fall in Indian startups. Byju Raveendran turned stadium-sized CAT classes into a learning app launched in 2015, and the pandemic made it India's most valuable startup, worth $22 billion by 2022. To keep growing it bought Aakash, Epic, WhiteHat Jr, Great Learning and others, borrowed $1.2 billion and spent heavily on sponsorships such as the 2022 FIFA World Cup. When schools reopened, revenue fell short of plans, accounts were delayed, Deloitte resigned as auditor in June 2023 and lenders declared default. A BCCI petition over Rs 158.9 crore of sponsorship dues pushed Think and Learn into insolvency in July 2024, and it has stayed there since. The company is headquartered in Bangalore, India. The once-massive edtech decacorn was founded in Bengaluru, India, executing one of the most aggressive growth strategies in startup history before suffering a catastrophic, multi-billion-dollar collapse in valuation.

Duolingo, Inc.: Duolingo took language learning, long sold as expensive boxed software, and rebuilt it as a free mobile game. From Pittsburgh, it now runs the largest consumer learning app by usage, with 58.7M daily active users in Q2 2026, and has grown into a profitable public company with more than $1B in annual revenue. The massively popular language-learning platform was founded at Carnegie Mellon University in 2011, aggressively utilizing intense gamification, an iconic green owl mascot, and massive data analytics to completely dominate the global education tech market.

BYJU'S and Duolingo, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between BYJU'S and Duolingo, Inc..

BYJU'S business model: BYJU'S made most of its money selling multi-year learning packages, not app subscriptions. Free lessons in the app generated leads, and a large field sales team visited families to sell courses bundled with tablets and SD cards, often paid for through loans arranged with NBFC lenders. In FY2020, sales of tablets and SD cards loaded with course content brought in Rs 1,676 crore, or 70.4% of operating revenue; reference books added 23.5% and tuition and service fees the rest. After the 2020-21 acquisitions the group also earned classroom fees through Aakash and BYJU'S Tuition Centres, subscriptions through Epic in the US, and course fees through WhiteHat Jr and Great Learning. Criticism of hard selling and the end of NBFC loan partnerships later squeezed collections.

Duolingo, Inc. business model: Duolingo runs a freemium model. All core lessons are free, which builds a very large audience (133.1M MAUs in Q4 2025). The company then converts its most engaged learners into paying subscribers: Super Duolingo removes ads and gives unlimited hearts, while the higher-priced Duolingo Max adds AI features such as Video Call and Explain My Answer, and Family plans bundle up to six users. Subscriptions are the largest revenue line. Free users are monetized through ads, and Duolingo also sells the Duolingo English Test, an online proficiency exam used in university admissions, plus in-app purchases like streak repairs. Because most users arrive organically through word of mouth and social media, marketing spend stays relatively low, and app-store fees are a major cost of revenue.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of BYJU'S stack up against those of Duolingo, Inc..

BYJU'S competitive advantage: At its peak BYJU'S had three advantages no Indian rival matched: a library of animated K-12 and test-prep lessons, a household brand built on Shah Rukh Khan ads and the Indian cricket team jersey sponsorship from 2019, and billions of dollars of venture capital that let it buy competitors such as Toppr, WhiteHat Jr and Aakash. Most of that advantage is gone. The brand is now tied to the insolvency, the capital has been spent, and Aakash is controlled by Ranjan Pai's Manipal group.

Duolingo, Inc. competitive advantage: Duolingo's edge is engagement. Its product teams run continuous A/B tests on lesson design, streaks, notifications and leagues, and the company reported an all-time-high current user retention rate in Q2 2026. Billions of exercises completed each month feed its Birdbrain personalization models, and the Duo brand drives low-cost organic user growth that subscription-only rivals struggle to match.

Future prospects matter as much as current results. The growth strategies below explain how BYJU'S and Duolingo, Inc. each plan to expand from here.

BYJU'S growth strategy: There is no growth strategy in the usual sense. Since July 2024 the business has been run by an insolvency professional whose job is to preserve value and sell the company or its assets. Steps so far include selling surplus inventory and equipment, pursuing the Aakash stake and inviting bids for the remaining brands. An August 2026 auction of assets linked to a subsidiary was frozen by the NCLT after claims that goods worth about Rs 150 crore had been sold for about Rs 16 crore.

Duolingo, Inc. growth strategy: Duolingo is growing in three ways: adding daily learners through product experiments and events (a June 2026 Streak Revival brought back 15.4M learners), pushing subscribers up to higher tiers like Duolingo Max with AI conversation features, and expanding into new subjects. Math and music launched in 2023, chess followed in 2025, and the company uses generative AI to build courses faster, which helped it add 148 new language courses in 2025.

A closer look at the financial trajectory of BYJU'S and Duolingo, Inc. rounds out the comparison.

BYJU'S: BYJU'S reported fast growth up to the pandemic and then stopped reporting on time. Consolidated operating revenue rose from Rs 1,306 crore in FY2019 to Rs 2,381 crore in FY2020, with a loss of a little over Rs 262 crore. The FY2021 accounts, delayed by a change in how multi-year course sales were recognised, showed revenue of Rs 2,428 crore and a loss of about Rs 4,564 crore. The FY2022 accounts, filed about 22 months late in January 2024, showed revenue of Rs 5,298 crore and a loss of Rs 8,245 crore. Accounts for FY2023 onward have not been filed. In November 2021 the company raised a $1.2 billion term loan in the US; lenders declared it in default in 2023, and a $200 million rights issue in early 2024 valued the company at roughly $225 million to $250 million, around 1% of its $22 billion peak. BYJU'S was once India's most valuable startup with a valuation of $22 billion, but it has since faced severe financial restructuring and massive valuation markdowns.

Duolingo, Inc.: Revenue grew from $531.1M in 2023 to $748.0M in 2024 and $1.038B in 2025, while net income reached $414.1M in FY2025, helped by a low tax rate. Growth slowed in 2026: revenue rose 26.6% in Q1 and 18.3% in Q2 to $298.5M, while total bookings rose only 8% to $289.1M. Q2 EPS was $0.66 versus $0.91 a year earlier, mostly because the tax rate normalized. Management guided 2026 revenue growth of 15-18% (about 16% point estimate), bookings growth of 10-12%, adjusted EBITDA of about $320M, and free cash flow above $375M.
