About Us
Understory was founded by a group of college friends who read a lot growing up but stopped reading as much during our busy college years. After graduating, we wanted to rebuild our reading habit through friendly competition and formed a shared spreadsheet where we could all log our reading!
The group continued to expand and we all saw substantial improvement in our reading frequency! With our backgrounds in computer science, we knew we could build an app to create a better user experience, which formed the basis for Understory.
We knew we wanted to use our platform to make an impact in the world, and environmental conservation is a cause we are passionate about. With the plant-themed foundation, the in-app and real-world trees were the perfect way to tie the charitable contributions to reading progress.
Currently, we work on Understory in addition to our day jobs and graduate school programs. We are excited for you to join our community to build a better reading habit and build a better world!
