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.

Callisto Campus, originally a project of SHI, launched in August 2015 at the University of San Francisco and at Pomona College. Callisto’s successful pilot and a growing demand for the system both within and outside of college settings led SHI to focus and rebrand as Callisto in the summer of 2016. Callisto's mission became to combat sexual assault, support survivors, and advance justice.

In 2018, Callisto expanded beyond college campuses to support professional industries. Callisto Expansion allows individuals who have experienced sexual assault or professional sexual coercion in a workplace environment to securely create an encrypted entry of their incident into our matching system.
