Clever

YCombinator

The platform that powers technology in the classroom.

Clever is a single platform for all of your digital learning programs. Founded in 2012, Clever was started by educators and technology professionals who knew that schools, teachers, and students could all benefit from the amazing learning software that was available, but key challenges stood in the way of accessing the technology. Today, half of K-12 schools in the U.S. use Clever to give students and teachers single sign-on access for any resource or file they need, and to automate software account setup and updates for district administrators. Clever gives teachers time to teach, helps districts be better informed, and makes using applications in the classroom effortless. We are a team of more than 100 people passionate about education. If you feel the same way, you should see our openings at https://clever.com/about/jobs.

CodeCombat

YCombinator

Game that teaches computer science to middle and high school kids.

CodeCombat is a multiplayer programming game for learning how to code. With thousands of schools and millions of students, we are bringing K12 computer science education to everyone, regardless of gender, race, or background. Everyone should have the opportunity to learn. The ultimate goal of CodeCombat is to bring more users into the field of computer programming by making the logic and syntax more accessible and enjoyable to learn. The end game is to educate a whole new generation of computer programmers that started their journey by slaying ogres and defending their castles from oncoming enemy hordes. We teach Python, JavaScript, and other languages directly in the browser. Teachers with no computer science background can get started in five minutes. In a world where all programmers have had to be second-language learners, do you want your students to become native speakers of code? Let's chat about bringing CodeCombat to your school!
