About Duolingo
Duolingo is a freemium language-learning app founded in the United States in 2011, helping people build a daily habit of practicing a new language.
Why it’s a challenger
Education brands are expected to be earnest, polished and reassuring, while language apps have long struggled with learners quitting. Duolingo turned its mascot into a menacing, meme-able internet personality that pushes users back to daily practice, then let the character loose across TikTok, celebrity stunts and pop culture crossovers. In 2025, revenue rose 39% to $1.04 billion.
This brand is in the Rival 50 2026 list. The report’s deep dives cover 14 of the top 20.
Reviewers’ view
Reviewers credited Duolingo’s game-like approach to learning and Duo the Owl, a recognizable character anchoring very distinct branding. They also pointed to unconventional, entertaining campaigns that lean into the owl’s chaotic persona and have repeatedly gone viral.
