In today’s episode ofThe Eric Ries Show, I am joined by Luis von Ahn, CEO and co-founder of Duolingo.
With Duolingo, his mission was simple: make language learning accessible to everyone—not to build a for-profit company. Fast forward to today, and Duolingo has grown into a $17 billion business with a reported 90% of the online daily active users in the language learning market.
In our conversation today, we discuss the following topics:
• How hiring an intern led to Duolingo’s viral mascot
• Duolingo’s revenue strategy that helped their stock be up over 100% in the past year
• How only 10% of users pay but make about 30% of the revenue in the education app category
• The newly published Duolingo Handbook and its critical role within the company
• How turning learning into a game changed everything
• Why Duolingo spent the first five years focusing on improving retention
• Duolingo’s unique approach to experimentation and how to apply it
• Why Duolingo isn’t focused on market investors but on building a 100-year company
• And much more!
