Gina Gotthilf, Vice President of Growth at Duolingo, joins Cheddar to discuss the launch of its Chinese course, the most asked-for language since the company launched in 2011. She said it's taken this long because the app wasn't designed to teach characters and "tones", which are fundamental to the Chinese language. The lessons are based on themes like greetings, food, travel, sports, business/finance, culture, and even Chinese internet slang. Gotthilf says one of the reasons Duolingo has taken off is because of how it's "gamified" learning. It aims to make using the app while in line for coffee, on the train to work, or waiting for a flight both fun and quick. People can learn at their own pace while being entertained in the process. The company has raised a total of $108.3 million in funding and is currently valued at $700 million. The future plans aren't to keep adding new languages, but to increase the efficiency of the courses already launched. So far 200 million subscribers have started learning a new langage.
