What they did
Duolingo Plus (2017): no ads plus fully offline use; because the purchase page looked thin with two features, added a third line 'Support Duolingo's mission', echoing what users said in reviews.
What happened
Guest believes most or about half of early buyers purchased to support Duolingo, the rest for no ads, little for offline. Started a revenue run rate.

In their words
Sub Club by RevenueCat · Why Your Free Users Are Your Real Growth Engine – Cem Kansu, Duolingo CPO“So we wrote a line there that was the thing that users were telling us, which is support Duolingo in its mission of free education.”
“And honestly, what I think we saw happen was probably majority of users early on bought it for the fact that they enjoyed Duolingo so much and wanted to contribute back.”
