Our story

It started with Danny

Dellis began with Danny, a young boy in elementary school who loves writing books, making pictures and building STEM projects. His imagination inspired a place where kids' creativity can come to life.

We believe in a world where everyone feels accepted and valued. Our books, songs and products celebrate what makes each of us different, and every purchase helps young kids keep dreaming, creating and imagining.

Empowering minds, celebrating differences.
