Duolingo: The evidence: origins and growth
In a 2018 interview, Gina Gotthilf described Luis von Ahn’s TED talk as a source of early Duolingo users. She arrived when the product had three million users, initially used PR, and later led growth experiments. Her background included philosophy and neuroscience studies and Latin American growth work for Tumblr. She says communications skills helped engineers and designers work together. [1]
