Who we are

Quizlet was started 10 years ago when Andrew Sutherland created a tool to help him study for a high-school French vocabulary quiz. He aced the test, so his friends asked him if they could use the tool too. Friends shared with friends, and Quizlet grew - a lot.
More than 10 years later, students have completed more than 3 billion study sessions, we have a fast-growing team (and we're hiring), and we’re backed by a great group of investors: Fred Wilson at Union Square Ventures, Greg Sands and Mark Selcow at Costanoa Ventures, Tory Patterson at Owl Ventures, Ho Nam at Altos Ventures and Dave Margulius.
