Quizlet has always been an unconventional company. I never intended for it to be a business; I started it because I needed a tool to study for a French class when I was 15 years old. I put it online because I thought a few friends of mine might benefit from it. Now, Quizlet is used by 25 percent of all U.S. high school students every month, and we’ve achieved that entirely through word of mouth.

Quantcast ranks us 50th in traffic among all U.S. websites. In the past few weeks, we’ve surpassed 100 million study sets created and one billion study sessions completed. We’re now used by 40 million people every month, and by learners in almost every country of the world every day. Roughly half of those learners use Quizlet on mobile devices. We’ve accomplished all of this with a team of only 32 people, half of whom we’ve hired since February.

We’re also unconventional in that we grew for ten years without raising venture capital money. Well, we’ve decided to change that!

I’m thrilled to announce that we’ve raised a $12 million Series A funding round, led by Fred Wilson at Union Square Ventures and Greg Sands at Costanoa Venture Capital. Fred and Greg have both joined our board. Also participating in the round are Owl Ventures, Altos Ventures, Geoff Ralston, Tim Brady, and Greg Brockman. We’re lucky to be working with investors who support us in building a mission-driven company.

Why did we finally decide to raise money? We’d already built a successful, self-sustaining business. We had millions of dollars in revenue that could fully support the team we’d built.

But it was time to be more ambitious, and that meant aggressively expanding our team and product.

Given the millions of people who already use and love Quizlet, we believe the Quizlet platform can reach all one billion students in the world. Because students and teachers contribute the materials they use for learning on Quizlet, we can provide a service that accommodates every curriculum in every educational setting. With the rise of inexpensive devices and broadly available Internet, it’s just now becoming possible to build an education platform that truly everyone can use.

As we expand, we also have a responsibility to think deeply about how learning on Quizlet works, and how we can make it better. We can help move education systems away from cramming for tests and forgetting everything a week later. We’re launching our first effort in this direction today, with Long-Term Learning, a set of tools and analytics for building cumulative knowledge over long periods of time. Over the next couple years, we will be building tools and activities that will help students achieve deep understanding and mastery of material, moving beyond our roots in memorization.

Our process for hearing feedback from our users will be critical to this expansion. At present, we individually respond to roughly 10,000 pieces of feedback per month. We visit classrooms several times a month, where we observe students and teachers using new features. Everyone on the team participates in these visits, and many of our best ideas come from classroom observations. We developed a new game called Gravity, also launching today, after students asked us to make our games more fun.

Over the years, the highlight of the experience for me has been meeting the people who use Quizlet. Our team owes all of our success to them. We’ve met Chinese grandmothers using Quizlet in community college to learn English. We’ve met waiters who used Quizlet to study for their ServSafe exams. We’ve met many students from underserved communities who have said that using Quizlet is one of their favorite parts of school, and who have built great study habits because of it. I feel strongly that Quizlet as a company should reflect the diversity of this learner community, and therefore we aspire to hire one of the most diverse teams in the business. Please take a moment to check out our job openings.

It’s fitting that we got our funding just as we turned ten. We’ve just completed a fantastic decade of hard work, but there’s a very palpable feeling at our office that the most exciting and impactful work is still ahead of us.

    I am so happy for Quizlet! I am a frequent user and my grades definitely wouldn't be what they are without quizlet. <3 great job yall!

  30. donna_mcinvale

    I have been so impressed with Quizlet! Its ability to boost memorization in the grammar stage of learning a subject assists in future success in the dialectic and rhetoric stages. Society had, in many arenas, moved past memorizing information, having the misguided notion that memorization is a waste of time. However, memorization of the basic facts, or grammar, of any field provides a solid foundation for mastery. I was excited to see your new tools, "Long-Term Learning, a set of tools and analytics for building cumulative knowledge over long periods of time." I look forward to your expansion of Quizlet to include helping students "put the pieces together" and use their knowledge to teach, inform and persuade others.

    So glad to see gravity available as a game option!

  36. joanna_17000 TEACHER

    This new game of yours kicks ass! (Pardon my language) but the graphics are WAY betterthan old Race. However given the dimensions of the screen (rectangular, not square, sadly , any more) you have less time to think. I really appreciate 3 modes of difficulty, but as I start using quizlet with kids as young as 7 or 8 , they are not quick at typing, and struggle even with the easy mode. Could you consider adding extra slow/easy? Thx:)

  37. joanna_17000 TEACHER

    And please add a memory game! It's a classic and fun way of studying!

  38. Hackster509

    yay new game

  39. xXxYolOSwaGerrxXx

    gravity is MUCH funner than space race, space race is old and slow, kid won't want to do it but now kid probably want to do it

  40. jeannamorgan

    great job! I have a's because of you! I also won the spelling bee using the speller part!

  42. Neidakat125

    Quizlet's the best for studying! Congrats jeannamorgan for winning the spelling bee and the A's.

  43. meimei007

    I have to be honest, at first I used to have a burning hate for Quizlet because I thought it wasn't going to help. Why? I'm one of those people who wouldn't study for anything and somehow miraculously pass with flying colors. Although, this year proposes a challenge to me thanks to having all Honors classes, and then realizing I couldn't wing it anymore like I used to... Therefore, I came back to Quizlet on a new account... Using it repeatedly again, and again, and again... Little did I realize, this actually helped me out more than I thought! I just wanted to type thank you for helping not only I, but everyone else here as well. I hope Quizlet keeps on taking an amazing direction (Like they are already) to becoming utilized by more individuals around the world, and to have great success in the near future! Thanks again! ::::)

  51. mferrucci

    Thank you. I love Quizlet and have been using it for years. I have used it to pass my college and graduate school exams. As a special education teacher, I have also used it with my special education students, so they can learn vocabulary. As a speech pathologist, I make flashcards for my students to practice their articulation and language skills. Now, my own children are using it to learn how to read music, so they can play the piano better. Keep up the great work!

  52. AgentDolly

    I've been here for a few years, and Quizlet really changed the way I learn. Thank you so much guys, and continue to make progress.

  74. Alicia_Halhed5

    Such a helpful study tool! I got into using Quizlet in high school and now I'm in university with a new university-oriented profile. I've recommended Quizlet to my friends and they all adore it.

  75. anothercollegekid02

    As you can tell by my username, Quizlet is greatly helping me in my education. I don't have to carry around boring flashcards or, in fact, spend tedious hours creating them. Quizlet is so effective in the addition that it turns studying into a rewarding activity and game. I really love that I am able to transform my online sets into study guides, matching sets, as well as narrow down the terms I am having difficulties with. I especially admire that Quizlet has a free account option, unlike so many websites these days where there are premium prices and monthly pays. As a full-time college student, I can't always shell out extra money - and thus, I admire Quizlet for maintaining its free option. This site is great - with clearly a bright and generous team that works behind it to make it all happen. Thank you so much for helping so many people & Happy Holidays, Andrew + Quizlet Team!

  88. martin_smith8 TEACHER

    https://quizlet.com/137540543/scatter Excited that, having used Q since January and created almost 400 sets already,there has been a minor learning revolution in our most staid of Hungarian schools, here in Mateszalka.A butter mountain of computers having led to the unexpected repatriation of 11 year olds to the 'small computer room',we now have Q de rigueur for all classes except Grade 1; and the most astonishing thing is that the Teaching Profession can now be seen as ready to split into Preparers and Presenters (like the English legal system) inasmuch as all the hard work is done before I arrive at class. The students do it all: work out how to create an account, in spite of their tender age, stray into Turkish,Chinese,Russian and French sets, enjoy all my materials, even create instinctively things within my project aims, so that we have created a group account.

  89. martin_smith8 TEACHER

    As to new directions, I am gratified at the emerging global vision of the company and believe that a subtle approach can enable Q to build levels which privilege unconscious learning. This is often counter-intuitive, and needs thousands of sets along the lines of the example I have just finished and show you above, which are cutting edge. This is perhaps the first ever Q set to use music as a prompt, but recording it pushed current Q technology beyond the limit.Re your:' We can help move education systems away from cramming for tests and forgetting everything a week later. We’re launching our first effort in this direction today, with Long-Term Learning, a set of tools and analytics for building cumulative knowledge over long periods of time...' which echoes my comments on tests vs learning, be careful not to gild the lily. Deep Q, as described to Olivia, remains my vision. Videos? No!
