Our Take
A proven technical founder leads elite engineers who create a free learning app that makes learning simple and engaging.
Years of retention-first design now produce high earnings per worker and steady cash from loyal users.
Low hiring growth, strong user data, and ample cash let the company fund growth without strain.
What To Watch
Watch AI being used effectively to release new engaging courses, and make the MAX subscription worth the $.
Watch how new courses like Chess lift paid subscribers; if adoption grows, Duolingo opens entirely new learning markets.
Watch revenue per employee; keeping it near $1M would show the company can scale without adding costly headcount.
