Duolingo stats and FactsPlease note that some of these Duolingo stats are easier to find than others, so some of these are based on news reports and not official company tallies. All stats are linked to their source unless it was sent to me directly from the company. No stat listed on DMR should be considered in making any type of investment decision. In other words: This is the best I can find, but I don't guarantee anything.
