Education Technology · Profile from Education Technology Research Companion
Duolingo, Inc.
The free-to-start, gamified mobile learning app that turned language study into a daily consumer habit. It became the most downloaded education app in the world and the largest listed pure-play consumer EdTech company, built on a freemium subscription model, relentless A/B testing, an aggressively online brand, and since 2023 a bet that generative AI can make the product both cheaper to build and closer to a human tutor.
