Decoding Duolingo: An Analytical Dive into the World's Leading Language App

Product Description

Duolingo is language-based educational app that offers a personalised learning experience to users from all around the world. It is the world’s leading language-learning platform and it manages over 20 million daily users enrolling in over 100 available courses in 38 languages (Curry, 2024). Duolingo was conceptulised in 2009 by Carnegie Mellon University professor Luis von Ahn and his Swiss-born post-graduate student Severin Hacker. Prof Von Ahn always thought that “free education will really change the world.”After witnessing how expensive it was for people in his hometown of Guatemala to learn the English Language, and driven by his desire to start an education-related project, he co-founded duolingo. A major reason why Duolingo is the leading language-learning platform is it’s accessibility, flexibility, and available to learners around the world. It’s main selling point is it’s game-like teaching method which is complemented by a user-interface that reasonates with people of all ages.

Product Vision

The aim of the product is to offer fun, personilized and universally accessible education to everyone. However, the scope of the aim has expanded to involve making universally free education, the best education. It also incorporates new teaching methods while expanding it’s catalogue of language course. Today, Duolingo is the world’s leading language-learning platform which is the result of the growth of the product turning it’s conceptual vision into a reality. Noticeably, the success of the product can be attributed to it differentiating itself from competitors by aligning itself to the needs and challenges of the market which includes creating an engaging free educational platform which would somehow meet the personalised needs of everybody, from everywhere, at anytime.

Development Journey

The development journey started with the product ideation process where 3 major principle were employed in order to create a product that stands the test of time:

1. Take the long View: this basically means making decisions based on the best outcome for the product even though such decision would take the most amount of time,“If the best proposal is going to take us three months to build, I want them to choose that idea over the one we could ship in three weeks but is hacky and only OK.”. Duolingo sometimes finds it difficult to decide on mechanics like push notifications that can grow daily users or investing larger time and resources in mechanics like the streak system that can cultivate habits for long-term users. Take the long View. Doing what is best for users in the long-term would overall grow a dedicated and loyal consumer base

2. Build for the Global User: It is necessary to include scalability to the product ideation/thought process. Regardless of whether the business is planning to go big or operate within a small region, considering the international audience would help increase the product appeal. Duolingo employed this process from the get-go and that was one of the reasons why it was able to gain a waiting list of 500,000 people just before it’s launch. Think of it as the product’s “seam allowance”.

3. If it can be better, make it better: This is the direct opposite of “if it ain’t broke don’t fix it”. Take for example Duolingo’s interface that has been changing ever so slightly over the years. Although, nothing was wrong with it ( pressumably), the design team still strove to improve something with nigh negligible faults. This is what this principle is about.

Duolingo's success is a testament to the power of PLG. By focusing on creating a user experience that's intrinsically engaging and rewarding, they've built a product that people genuinely enjoy using. This not only translates to high user engagement but also fosters brand loyalty and organic growth (Dezy It, n.d.).

Key Development Challenges

Every product in it’s lifecycle must experience bottlenecks or limitations. Duolingo experienced and is still experiencing challenges involving organic growth. The rate at which different users learnt and absorbed information led to disatisfaction among the consumer base. This was addressed by creating a multi-faceted learning system that includes voice conversational practice, and tests, although, it proved a challenging problem at first. Another challenge in the development phase was ensuring that the content being taught was culturally and linguistically accurate enough to launched. This proved more difficult in the startup phase where human resources were few and far between.

However, the main challenge was keeping the project afloat. It is difficult to making money while the main selling point of your brand is “free education”. Although, this challenge didn’t persist for long as we’d see in the next section

Major Pivots of Duolingo

1. From Free to Freemium: Initially, Duolingo was entirely free. Over time, they introduced Duolingo Plus, a subscription service offering an ad-free experience and additional features1.

2. Introduction of Duolingo English Test: In 2016, Duolingo launched its own English proficiency test as an alternative to traditional tests like TOEFL and IELTS.

3. Expansion to Kids and Advanced Learners: Duolingo introduced Duolingo ABC for kids and revamped their English courses for advanced learners.

Technology or Design Innovations

1. Gamification: Duolingo gamified language learning by breaking lessons into bite-sized, game-like activities, making learning more engaging.

2. AI-Powered Lessons: Duolingo uses AI to create and personalize lessons, ensuring they are at the right difficulty level for each learner.

3. Duolingo Incubator: This platform allows volunteers to help create new language courses, expanding Duolingo's course offerings.

4. Transition to Scala: Initially built on Python, Duolingo transitioned to Scala for its backend to handle the growing user base and complexity.

Launch Strategy

The Product’s initial approach was heavily invested in offering “free education”, gamified-language learning, and accessibility to everyone. By offering, engaging and simplified lessons from the get-go it was easy to grow a steady user base. Marketing itself as a “fun, accessible, and high-quality language learning platform” left an indelible mark in the workspace and market place, prompting many tech companies to try to emulate them by delving into the language learning marketplace.

The Launch challenges were similar to the development challenges with the inclusion of scalability - they couldn’t anticipate how successful and popular they would become.

Market Reception

Even before it’s launch, Duolingo was already gaining traction comparably to most other revolutionary brands. It amassed a waitlist of over 500,000 people before it’s launch and in little over a year maintained 5 million users and was the No.1 free education app on google play store.Duolingo’s user base has grown exponentially, with impressive user adoption metrics. As of Q3 2024, Duolingo reported 37.2 million daily active users (DAUs) and 113.1 million monthly active users (MAUs). Additionally, the platform boasts over 8.6 million paid subscribers, reflecting its significant commercial success.

Critically, Duolingo has received numerous accolades for its contributions to education technology. The app has been recognized with awards such as Google Play's Best of the Best and Apple's App of the Year. Its revenue growth has been equally impressive, with Q3 2024 revenue reported at $192.6 million, marking a 40% increase from the previous year. This success highlights Duolingo's ability to balance free access with effective monetization strategies.

When compared to competitors like Babbel, Rosetta Stone, and Memrise, Duolingo stands out due to its freemium model and gamified approach. While Babbel and Rosetta Stone offer in-depth courses for a fee, and Memrise focuses on vocabulary through spaced repetition, Duolingo’s comprehensive and engaging platform attracts a broader audience.

In conclusion, I personally feel that I’ve garnered enough knowledge for the next class from this assignment. Researching and analysing Duolingo was stressful but fun and insightful. The processes that PMs go through is somewhat similar to a data analyst - at least that’s the conclusion that I came to. Duolingo is a solid product managed by highly experienced and innovative leaders and it would maintain it’s success and traction if it keeps being spearheaded under the right management. I also discovered that a brand’s image is very important because how you present yourself initially might be how you’d eventually come to be known, even if there is a major restructuring in the product. Finally, I saw firsthand through my analysis, the presence of a highly innovative and intelligent product manager which was evident by how much the key responsibilities and principles of product management were present during the production, launch and runtime phases. I would like to employ these principles in my future endeavors while still learning more about product management.
