Duolingo has raised $183 million across many rounds, including a $35M Series H (Nov 6, 2020) and multiple earlier growth rounds and a Post-IPO financing (Feb 15, 2022). Founded in 2011, Duolingo turned gamified lessons into a global learning marketplace for over 500 million users. Funding accelerated product development (adaptive learning, certification, and enterprise offerings), international expansion, and investments in mobile-first UX and data science for personalized learning. Capital also supported the company’s enterprise learning product and content partnerships that connect outcomes to measurable career skills.
