It’s hard to believe that over one million students have used CodeHS.

I can barely count to a million.

And now each month 13,000 classrooms use CodeHS.

It’s an exciting milestone since we started CodeHS in 2012. We’ve now helped students, teachers and schools all over the world get started learning coding, and I am hopeful that over the next few years millions more students will learn on CodeHS.

When Zach and I had started CodeHS, it really seemed to us that people should learn coding. But when we started, it did seem sort of fringe — most schools didn’t really have it as something on their radar. Today, more schools and districts are adopting CodeHS each day to bring in best-in-class computer science programs.

Thank yous (I’d like to thank the academy)

There are a lot of thank yous to go around since building CodeHS so far has been a team effort, from the schools to customers to team members to investors and partners.

Thank you to all the teachers who gave CodeHS a try early on, the customers who have signed up, and everyone who has provided feedback to help make the site better.

Thanks also to the people who helped us get CodeHS off the ground: Eric Conner helped us create the first prototype in the Launchpad class at Stanford taught by Perry Klebahn and Michael Dearing. Susha Roy, Kurt Hepler, Max Magnuson, Emily Kuo, and Will McCambley joined us very early on as the first CodeHS team members.

Thanks to the teachers and computer science teachers that we had over time- my high school CS teacher Steve Svetlik, who taught the first CS class I took. Thanks also to the Stanford CS professors who we took classes from and also helped us start teaching computer science in the CS106 and CS198 program including Mehran Sahami, Steve Cooper, Keith Schwarz, Eric Roberts, and many others. Also Lekan Wang, who interviewed me for CS198 and accepted me to that program which really helped us get interested in this area.

Thanks to the help from ImagineK12, which was a new edtech incubator when we joined in 2012 and now has really helped many of the premier edtech startups over the last 10 years, including Tim Brady, Geoff Ralston and Alan Louie.

Thanks also to StartX, where we worked in 2012 and the community of people there.

Thanks to the early advisors and investors who thought this could be an interesting idea before coding seemed obvious — Jay Borenstein, Mitch Kapor, Brian Dixon and Kapor Capital, Craig Sherman, Frank Serrino, Rob Hutter and Michael Staton at Learn Capital. Also thanks to Adam Knight, Jeff Chapman, Jason Chicola, Seven Peaks Ventures, NewSchools Seed Fund, Mark Platshon, Ellen Levy and Angel List.

And thanks to our team at CodeHS who help students and teachers every day — and really do make a big impact.

So thanks for using our site! And hope we can continue to make it better for you in the future.
