How Humans Grew Acorn Brains and How Duolingo Built a $700 Million Company Without Charging Users

Introduction

When it comes to long-term crises, humanity's response has often been slow. However, our ability to think and plan over long timeframes is a remarkable cognitive ability that sets us apart. In this article, we will explore the evolution of our brains and how it relates to our response to long-term challenges. We will also delve into the story of Duolingo, a language-learning platform that built a successful company without charging its users.

The Evolution of Acorn Brains

Humans possess two distinct parts of the brain that play a role in our decision-making processes. The Marshmallow Brain focuses on instant rewards and immediate gratification, while the Acorn Brain, located in the frontal lobe, allows us to think, plan, and strategize over long timeframes. Our ability to tap into this Acorn Brain is crucial if we are to tackle long-term challenges effectively.

Evolutionary psychologists and archaeologists offer various explanations for how our brains evolved this remarkable cognitive ability. One theory suggests that our protohuman ancestors developed the capacity for wayfinding, a survival skill that allowed them to navigate and orient themselves in physical space. This ability to plan and navigate over long distances laid the foundation for our long-term thinking abilities.

Another explanation, known as the "grandmother effect," highlights the importance of older post-reproductive females in providing vital childcare and support to increase the survival chances of the young. This relationship of trust and reciprocity, which spans across generations, reinforces the value of thinking and planning for the future.

Lastly, our genius for toolmaking and complex action sequences enabled us to plan and execute actions with long time horizons. The ability to plan making a stone tool paved the way for other forward-looking actions, such as crop rotation or building structures like pyramids.

The Story of Duolingo

Duolingo, a language-learning platform, achieved remarkable success by sticking to its original mission and vision while adapting its monetization strategies. The founders identified a large market of people who wanted to learn a new language but couldn't afford expensive software like Rosetta Stone. By going after this bigger market and using A/B testing to develop their product, Duolingo was able to grow into a $700 million company.

One of the key factors in Duolingo's success was its focus on gamification and providing a sense of progress to its users. The addition of streaks, which tracked users' daily language learning activities, kept them engaged and motivated. This sense of progress and achievement encouraged users to continue using the app regularly.

Duolingo also found a unique way to monetize its platform without charging users directly or resorting to ads. By making translation a byproduct of language learning, Duolingo generated revenue by selling translated content to other companies. This approach allowed them to keep the product free and accessible while still providing value to businesses.

Retention and engagement were crucial for Duolingo's growth. The more users used the app, the better their language learning outcome became. Features like a mobile app and push notifications further enhanced engagement and made the app addictive.

While Duolingo faced challenges in finding sustainable monetization strategies, the company remained committed to its mission of providing free language education. They experimented with various options, such as partnering with other companies and eventually introducing ads and a paid plan. These decisions were made with the intention of maintaining a good user experience while still generating revenue.

Three Actionable Advice

1. Stick to Your Mission and Vision: Duolingo's success can be attributed to its unwavering commitment to providing free language education. By staying true to their mission, they were able to build a loyal user base and attract investors who shared their vision.

2. Go After a Big Market and Experiment: Duolingo tapped into a large market of language learners who couldn't afford expensive software. By experimenting with their product and using data-driven decisions, they were able to create a platform that resonated with users.

3. Focus on Retention and Engagement: Duolingo's gamification features, such as streaks, kept users engaged and motivated to continue using the app regularly. Retention and engagement are essential for building a strong and growing user base.

Conclusion

Humans possess the unique ability to think and plan over long timeframes, thanks to our Acorn Brain. This cognitive ability is crucial for tackling long-term challenges such as the climate crisis. Similarly, Duolingo's story showcases the importance of sticking to a mission, focusing on a large market, and experimenting with monetization strategies. By providing a sense of progress and maintaining user engagement, Duolingo was able to build a successful company without charging its users.
