Joie Yen, the owner of ENJOY STUDIO LLC and the mom of a multilingual boy, introduced Chameleon Reader worldwide in 2019.

Using her user experience background, she interviewed many multilingual families to make sure the design of Chameleon Reader was easy to use and meets user needs.

With the help of engineers in Taiwan, they added new features to the pen. For the stickers, user manual, packaging and other items, she worked with a designer friend, coming up with the chameleon brand.
