Who killed Duo? How Duolingo built a brand on entertainment

Today, I’m joined by James Kuczynski, Creative Director at Duolingo, and Dan Salkey, Founding Partner at Small World, for a conversation on how to build truly entertaining brands.

Fresh off their SXSW panel titled "Entertain or Die", named after a report by Small World, we explore how Duolingo has built such a standout brand, particularly through the rise (and death...) of their iconic mascot, Duo.

In the first half of the episode, I chat with James about Duolingo’s brand success, why they decided to "kill off" their beloved mascot, and how giving creative autonomy to their team has been key to their growth. In the second half, I speak with Dan about the most entertaining brands in the world today—and the specific traits you can apply to make your own brand more entertaining.
