Quizlet, Inc. is an education technology company headquartered in San Francisco, California, founded in 2005 by Andrew Sutherland, who built the first version as a 15-year-old student to help himself study French vocabulary. The platform provides digital study tools including flashcards, practice quizzes, and collaborative learning games, operating under a freemium model that offers basic features at no cost and premium features through paid subscriptions.
Quizlet's core product allows users to create and share study sets, which can be used across multiple study modes including Learn, Match, Gravity, and Spell. The platform serves a broad range of learners from K-12 students to college and professional exam candidates. Quizlet has reported over 60 million monthly active users globally, with significant adoption in the United States and international markets. In 2023, Quizlet introduced AI-powered study tools, including a feature called Q-Chat, a tutoring assistant built on OpenAI's technology.
Quizlet raised approximately $62 million in total funding across several rounds, including a $30 million Series C in 2015 led by General Atlantic and a $20 million Series D in 2017. The company was valued at $1 billion following its 2017 funding round. Lex Bayer, formerly of Airbnb, became CEO in 2019, succeeding founder Andrew Sutherland. The company has undergone workforce reductions in recent years, including layoffs in 2023, as it restructured operations around its AI product strategy.

Who Quizlet, Inc. competes with, and how they differ.
Chegg bundles subscription homework help, textbook rentals and AI tutoring under one paid plan, competing on breadth of student services rather than Quizlet's narrower flashcard and study-set focus.
Anki is a free, open-source spaced-repetition flashcard app sold as a one-time download rather than a subscription, appealing to users who want algorithmic control over Quizlet's social, ready-made study-set model.
Khan Academy is a free, donor-funded platform built around instructional videos and curriculum-mapped practice exercises, competing for the same study time through guided lessons rather than user-generated flashcard sets.
1 product reviewed on TopReviewedCourse Hero monetizes a crowdsourced library of course-specific study guides and past assignments via subscription, competing for last-minute exam-prep traffic rather than vocabulary and concept drilling.
Brainscape is a smaller, direct flashcard rival built around a confidence-based spaced-repetition algorithm, competing on study method rather than Quizlet's larger user-generated content library and game modes.
