Duolingo language learning application

Duolingo is the world's most popular language-learning platform, designed to make education free, fun, and accessible to everyone. The product was founded in Pittsburgh, Pennsylvania, and remains a primarily digital service developed and maintained by teams based in the United States.

Since its launch in 2011, Duolingo has grown from a crowdsourced translation project into a publicly traded educational technology giant. The brand is known for its gamified approach to learning and its iconic mascot, Duo the owl. The company manages its operations globally through its digital infrastructure, ensuring that its curriculum is available to millions of users across nearly every country in the world.
