Kids Can Code. We Help.

We put educators first

At Kodable, we believe that teachers are the gatekeepers of learning. So we've built our product from the ground up with teacher's needs in mind. From scripted lesson plans to automated assessment tools, everything we do is designed to help educators spend less time preparing, and more time teaching. Because that's where you make the most difference.

Chief Morale Officer

Mo is a dog. She does dog things. But more importantly she has been with Kodable since the very beginning, laying by Jon and Grechen's side long into the late nights when the first versions of Kodable were built in a living room. Surprisingly, she seems to be immune to the stresses of starting a startup. Top minds are currently studying her brain waves to understand how this is possible. Results so far have been inconclusive.



Assistant to the Chief Morale Officer

Pierre is also a dog. He also does dog things. However, unlike Mo, Pierre is constantly stressed about everything. This has prevented the advancement of his career as a Morale Officer at Kodable. Jon has suggested he find another calling. Pierre hasn't listened.

A note from the founders

We founded Kodable with a simple goal. We wanted to make it easier for people to teach their kids about computer science. In the years that followed, we've been overwhelmed with the response we've received from teachers, parents, and kids around the world. We never dreamed that something started at a kitchen table could be used by over 50% of elementary schools in the United States and over 200 countries around the world.

Jon started programming when he was 6, and knows firsthand the incredible effects it can have on people's lives. Nothing before in history has existed that can have such a transformational effect on a child's life - regardless of race, gender, or even economic background. Our mission today is simple - we want to bring that opportunity to every child in the world.

We're just getting started.
