Our take

Quizlet has built a large-scale business around simple-to-share and simple-to-use products. Its free flashcard maker helps students prepare for exams. Those insights fuel Quizlet Plus, the startup’s subscription product that charges an annual fee for access to more features, including tutoring services.

After a long period of runaway growth, during which the company achieved a $1 billion valuation, Quizlet has been somewhat buffered by the general market downturn affecting the tech sector in 2022, which hit EdTech particularly heavily. It has responded by a shakeup of its leadership team, appointing AirBnB and Starship Technologies veteran Lex Bayer.

With an entrepreneurial management team and a strong user base of over 60 million students and teachers, Quizlet seems likely to weather the current economic situation and resume its growth in the near future.
