About Pillar Learning

Message From Our Founder


Hi, my name is Dayu, and I am the creator of Codi.

I grew up with classic PBS kids shows including Mr. Rogers, Reading Rainbow, and Sesame Street. Five-year-old me loved them because they were fun, entertaining AND (I had no idea at the time) they were good for me!

Only recently have I fully appreciated how much Mr. Rogers’ gentle words, or even just LeVar Burton's story readings, have aided in my own growth and development. As parents, and future parents, of a very technologically driven generation, I became worried that the educational entertainment of the past was on its way out.

That’s why I started Pillar Learning, Codi’s parent company. I wanted to leverage new technology to best support our future generations. At Pillar Learning, we believe in sticking to the roots of wholesome content and using technology in the right way.

Codi

Codi is a cute, smart toy that provides a fully curated audio experience with age-appropriate content. Codi is internet-connected to provide access to a variety of content and new updates, as well as smart recommendations to provide a personalized experience for your child. As a parent, you will have full transparency into your child's playtime, and you can have as little or as much control as you want.

Codi was designed with children's usage and learning in mind and approved by parents. We’ve tested more than 20 original concepts with hundreds of parents and their children, deciding on Codi’s final design only after every child loved and wanted to play with it. All of the materials and electronic components are carefully selected to not only bring great functionality, but also is durable, easy to clean, and comfortable for your child to play with. Codi will be rigorously tested to the strictest children's product standards to ensure that it will be completely safe and secure.
