Duolingo got there first, launching in 2011 — that's 1 year of extra runway. Coursera didn't arrive until 2012. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Coursera has about 1300 employees; Duolingo has about 850. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both Coursera and Duolingo compete in AI Education, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
