Duolingo’s marketing strategy, particularly its use of Duo, has been a key factor in the company’s success, and this case study will examine the company’s approach in more detail.

Company & Industry Background

Duolingo was founded in 2011 by Luis von Ahn and Severin Hacker, with the goal of providing free language-learning opportunities to people around the world. The company’s mission is to make education accessible and fun, and it has achieved significant success in the ed-tech industry. Duolingo offers courses in over 30 languages, and its platform is available on both desktop and mobile devices. The company’s revenue model is based on advertising and in-app purchases, and it has received significant funding from investors to support its growth. In the language-learning market, Duolingo competes with other popular platforms such as Babbel and Rosetta Stone, but its focus on gamification and social sharing has helped it to stand out.

The Business Challenge

In 2018, Duolingo faced a significant challenge in terms of user engagement and retention. While the company had achieved significant growth in terms of user acquisition, it was struggling to keep users engaged with the platform over time. To address this challenge, Duolingo’s marketing team decided to focus on creating more engaging content and leveraging social media platforms to reach a wider audience. The company’s goal was to increase user retention by 20% and to reach 100 million active users within the next year.
