Introduction

The Importance of Finding a Huge Target Addressable Market

Vinita and R identify extraordinary businesses and entrepreneurs by looking for those who have a large target market and a genuine passion for solving critical problems.

The Rarest Breed of Entrepreneurs

The combination of qualities that makes an entrepreneur unique can vary depending on the individual and their specific business. However, there are certain traits that are commonly associated with successful entrepreneurs. Firstly, a unique entrepreneur is likely to have a strong sense of vision and purpose. This means they have a clear understanding of the problem they are trying to solve or the opportunity they are trying to seize. In the case of Duolingo, the founders identified a gap in the market for accessible and free language education, and they set out to address this need. Secondly, a unique entrepreneur is likely to be highly adaptable and resilient. This means they are able to pivot their business strategy when necessary, learn from their mistakes, and persevere in the face of challenges. Duolingo’s founders, for example, faced numerous obstacles in the early days of their company, but they remained committed to their mission and continued to iterate and improve their product. Thirdly, a unique entrepreneur is likely to be highly creative and innovative. This means they are able to think outside the box, come up with novel solutions to problems, and continuously push the boundaries of their industry. Duolingo’s founders, for instance, developed a gamified language learning platform that leveraged the principles of habit formation to keep users engaged and motivated. Lastly, a unique entrepreneur is likely to be highly empathetic and customer-focused. This means they have a deep understanding of their target audience and are able to design products and services that meet their needs and preferences. Duolingo’s founders, for example, recognized the importance of creating a user-friendly and enjoyable language learning experience, and they designed their platform accordingly. In summary, the combination of qualities that makes an entrepreneur unique may include a strong sense of vision and purpose, adaptability and resilience, creativity and innovation, and empathy and customer focus. By possessing these traits, entrepreneurs like the founders of Duolingo are able to create successful and impactful businesses that address real-world needs and challenges.

The Fall of E-Commerce Companies

The Slow Poison of Customer Acquisition Costs

The massive fall of e-commerce companies occurred due to a combination of factors. Firstly, the e-commerce companies were not able to retain their customers. They were focused on acquiring new customers but failed to create a habit-forming product that would keep the customers engaged and loyal. This lack of customer retention strategy led to a high churn rate. Secondly, the e-commerce companies did not understand the importance of targeting specific markets. They were trying to cater to a global audience without realizing that different regions have different needs and preferences. This led to a one-size-fits-all approach, which failed to address the unique challenges faced by customers in different parts of the world. Lastly, the e-commerce companies did not adapt their business strategies to the changing market dynamics. They failed to recognize the potential of emerging markets like India, Africa, and South America, where there is a huge demand for life-changing solutions. By not addressing these markets, the e-commerce companies missed out on significant business opportunities. In conclusion, the massive fall of e-commerce companies occurred due to their inability to retain customers, their failure to target specific markets, and their lack of adaptability to changing market dynamics.

The Key to Cracking the EdTech Market

The key to cracking the edtech market is to create high-quality, engaging educational content while keeping customer acquisition costs in check and focusing on customer retention. This involves finding the right balance between providing valuable, challenging content and ensuring that students do not become frustrated and give up. Edtech companies should focus on creating products that become an integral part of students’ daily routines, incorporating interactive elements, gamification, and personalized learning experiences that cater to individual student needs. Additionally, edtech companies must be mindful of their customer acquisition costs and optimize their marketing strategies to reach potential customers in a more cost-effective manner. By doing so, edtech companies can build a successful and sustainable business model.

Duolingo’s Stunning Stats and Growth

Duolingo stands out from its competitors due to its exceptional user retention rate and the implementation of the “hooked model” in its design. This model, as described by Nir Eyal in his book “Hooked,” focuses on creating habit-forming products. Duolingo has strategically incorporated this model into its platform to keep users engaged and coming back for more. The hooked model consists of a four-step framework: trigger, action, variable reward, and investment. Duolingo’s design effectively utilizes each of these steps to create a habit-forming experience for its users. The trigger is initiated through push notifications and reminders, prompting learners to take action. This action is taken in anticipation of a reward, which includes experience points, streaks, and leaderboard rankings. As users continue to engage with the platform, they make a psychological investment in their learning journey. This investment, combined with the rewards system, leads to a trigger for further learning, bringing users back to the app. By focusing on user retention and habit formation, Duolingo has managed to achieve an extraordinary engagement rate, surpassing even popular apps like Candy Crush and Royal Match. In summary, Duolingo’s success can be attributed to its effective use of the hooked model, which creates a habit-forming experience for its users. This, in turn, leads to a high user retention rate, setting the language learning app apart from its competitors.

The History of Duolingo

Luis von Ahn and Severin Hacker, the creators of Duolingo, started the company in 2011 with a mission to make education free and accessible to people worldwide. They aimed to revolutionize language learning and testing by developing a habit-forming product based on the Hooked Model, as described by Nir Eyal in his book. The Hooked Model consists of a four-step framework: Trigger, Action, Variable Reward, and Investment. The Trigger serves as a nudge to action, such as seeing an ad. In Duolingo’s case, the Trigger could be the user’s desire to learn a new language or improve their existing language skills. The Action step involves the user engaging with the product, in this case, using the Duolingo app to learn a language. The Variable Reward is a crucial aspect of the model, as it keeps the user engaged and motivated to continue using the app. In Duolingo, this reward could be in the form of points, progression through levels, or positive reinforcement through the app’s mascot, Duo the Owl. Lastly, the Investment step encourages the user to invest time, effort, or even money into the product, further solidifying their habit of using Duolingo. This could be in the form of completing exercises, purchasing a premium subscription, or sharing their progress with friends and family. By strategically designing Duolingo based on the Hooked Model, von Ahn and Hacker have created a highly engaging and successful language learning platform. Today, Duolingo boasts over 800 million downloads and 2 million test takers worldwide, making it a company that has undoubtedly changed the landscape of language learning and testing forever.

The Golden Recipe for Learner Engagement

The golden recipe for learner engagement in edtech, as demonstrated by Duolingo, involves implementing the “Hooked Model” designed by Nir Eyal. This model consists of a four-step framework: Trigger, Action, Variable Reward, and Investment.

  1. Trigger: The first step is to create a trigger that nudges the learner to take action. This could be an advertisement, a notification, or any other external or internal prompt that encourages the learner to engage with the edtech platform.
  2. Action: Once the trigger is in place, the learner must be able to easily perform the desired action. In the case of Duolingo, this involves completing language learning exercises. The action should be simple, quick, and require minimal effort from the learner.
  3. Variable Reward: To maintain engagement, the learner must receive a variable reward for their actions. This reward could be in the form of points, badges, or progress indicators. The key is to make the reward unpredictable, so the learner is consistently motivated to continue learning.
  4. Investment: Finally, the learner should be encouraged to make an investment in the platform. This could be in the form of creating a profile, setting goals, or sharing their progress with others. The investment creates a sense of ownership and commitment, further increasing engagement. By implementing the Hooked Model, edtech platforms can create a habit-forming product that keeps learners engaged and motivated to continue learning. Duolingo’s success in achieving extraordinary engagement is a testament to the effectiveness of this approach.

The Hooked Model and Duolingo’s Design

Trigger: Push Notifications and Timing

Duolingo uses push notifications as a strategic method to bring users back to the app. The hook model, which is a four-step framework consisting of trigger, action, variable reward, and investment, is the basis of their approach. In the case of push notifications, Duolingo employs three unique strategies to engage users and form a habit-forming product. Firstly, the push notifications come from different personas, such as the app’s mascot, Duo, who has a playful and encouraging tone, and Lily, who is more like a sassy teenager. These personified guilt-tripping notifications create a sense of urgency and motivation for users to return to the app and continue their language learning exercises. Secondly, Duolingo uses AI and data analysis to determine the best time to send these notifications. They found that the optimal time is exactly 24 hours after the user’s last session. This technique is also used by other apps like Fin Shots, which further demonstrates its effectiveness in engaging users. Lastly, the push notifications are designed to create a psychological investment in the learning process. Users are motivated by the anticipation of rewards such as experience points, streaks, and leaderboard rankings. This investment in learning leads to a trigger for further learning, which in turn brings users back to the app. By implementing these strategies and following the hook model, Duolingo has successfully turned language learning into a habit-forming exercise, resulting in high user engagement and retention.

Action: Completing a Language Lesson

The smallest action a user takes in anticipation of a reward in Duolingo is opening the app and completing a 3-minute lesson on language learning. This action is taken in anticipation of rewards such as experience points, streaks, and leaderboard positions, which contribute to the user’s psychological investment in the platform. By completing these short lessons, users are motivated to continue learning and engaging with the app, ultimately forming a habit of language learning.

Variable Reward: Experience Points, Streaks, and Leaderboards

Duolingo uses variable rewards to keep users engaged by offering unpredictable rewards for completing lessons and maintaining streaks. When a user completes a lesson on Duolingo, they are rewarded with experience points (XP), which vary in amount, making it a variable reward. This XP contributes to the user’s day streak, which is another form of reward. Additionally, Duolingo offers badges as rewards for accomplishing certain tasks or staying consistent with daily practice. These badges serve as a form of recognition and reinforcement for the user’s efforts. The use of variable rewards in Duolingo’s design is strategically aimed at keeping users engaged and motivated to continue learning. By offering unpredictable rewards for completing lessons and maintaining streaks, Duolingo taps into the psychological principle of variable rewards, which has been shown to be highly effective in creating and maintaining habits. This concept is based on the Hooked Model, which states that to get a customer engaged with you, you must build a habit-forming product. In summary, Duolingo effectively uses variable rewards, such as experience points and badges, to keep users engaged. By offering unpredictable rewards for completing lessons and maintaining streaks, Duolingo effectively taps into the psychological principle of variable rewards, which has been shown to be highly effective in creating and maintaining habits.

Investment: Psychological Investment in the App

Duolingo has several features that make users psychologically invest in the app. Firstly, the streak feature plays a significant role in keeping users engaged. Similar to Snapchat, Duolingo rewards users with a streak for every day they use the app. This creates a sense of commitment and investment in the learning process. Secondly, the app uses a combination of multiple features that tap into users’ psychology. One such feature is the experience points system, which allows users to gain experience points as they progress through the lessons. This system creates a sense of accomplishment and progress, encouraging users to continue using the app. Thirdly, Duolingo has a leaderboard called the League, where users compete with 30 random participants who use the app around them. This feature adds a competitive element to the learning process, motivating users to invest more time and effort into their language learning journey. Lastly, the app uses the Hooked Model, which consists of a four-step framework: Trigger, Action, Variable Reward, and Investment. Duolingo strategically designs its app to incorporate these elements, ensuring that users are consistently nudged (trigger) to take action (using the app) in anticipation of a reward (experience points, streak, and leaderboard position). This process eventually leads to a psychological investment, making users more likely to return to the app for further learning. In summary, the streak feature, experience points system, the League, and the implementation of the Hooked Model all contribute to making users psychologically invest in the Duolingo app.
