Who We Are

We're engineers, designers, legal experts, researchers, and educators - united in our desire to create a world where sexual assault is rare and survivors are supported.


Our History

In November 2011, Callisto CEO Jess Ladd founded Sexual Health Innovations (SHI) while she was a graduate student at Johns Hopkins University. SHI was founded with the goal of creating technology to advance sexual health and wellbeing in the United States.

In 2014, SHI announced an initiative called Callisto at The White House Data Jam on Campus Sexual Assault.

A year-long pilot of Callisto launched in August 2015 at the University of San Francisco and Pomona College. Callisto’s successful pilot and a growing demand for the system both within and outside of the college setting led SHI to reorganize and rebrand as Callisto in the summer of 2016.
