Language learning platform Duolingo, a Pittsburgh, PA-based provider of a popular language learning app, raised $45m in funding.
The round was led by Google Capital with participation from previous investors.
The investment will enable the Duolingo team to make the platform even more adaptive and personalized, and to expand its presence in schools across the globe.
Led by Luis von Ahn, cofounder and CEO, Duolingo provides a mobile-first, adaptive, and gamified platform for people to learn languages.
It offers bitesized lessons that can be consumed in minutes, from anywhere.
