We're parents, educators, and computer scientists.

Our mission is to create a programming environment that lets kids explore powerful ideas while making real software.

Join us and empower your children to create.


Jocelyn Leavitt

Jocelyn was a teacher at the Dalton School in NYC, and has been working with constructivist, experiential project-based learning since her undergraduate days. She wished she had known what engineering was as a kid; she started this company so other kids would. She grew up in Honolulu and likes surfing, swimming, snorkeling, diving; pretty much anything that involves the ocean. She used to front a rock band and nothing can get between her and Chop’t.


Samantha John

Samantha fell in love with programming during her senior year at Columbia. Since then, she's been on a mission to introduce every kid to this amazing skill. She's been influenced by the likes of John Holt and Ivan Illich and cares deeply about empowering kids to learn on their own. She hails from the proud city of Detroit and can probably beat you barefoot in a marathon.


Liza Conrad

Liza has spent the last five years making computer science accessible and exciting. As the second employee at Girls Who Code, she grew the organization from a pilot into a national movement. At Hopscotch, she ensures that every kid finds a way to connect with coding. Liza is an Obama ’12 alum, and previously worked in education in Latin America. She’s an avid ocean-goer and knows where to eat on any corner in NYC. 


Rodrigo Tello

Mexican designer, bedroom musician, GIF maker. Originally educated as an architect, he started playing around with websites and computers by changing files’ extensions and opening them on a text editor when he was 11. Rodrigo believes the Internet can help us understand the world better and wants to make Hopscotch a tool for infinite creative expression.


Parents, teachers, and kids

Love Hopscotch

The more I use Hopscotch, the more I realize I’m teaching my students to think.

 — Paul, ICT Teacher

I love Hopscotch because when you create something, it feels like you have accomplished something amazing.

— Winning Monkey, Hopscotcher

This is best coding app I have ever seen for a mobile device! It’s intuitive, educational, and most importantly, fun!

— TheJanik4, family

My son, AJ, is loving Hopscotch and this has opened up another world of something that interests him - makes learning fun!

— Michelle, mom
