Callisto is a nonprofit US organization, created by Jess Ladd, aimed at supporting survivors of sexual assault and privately identifying repeat perpetrators. The organization has developed a series of tools, first "Callisto Campus", followed by "Callisto Expansion", and later "Callisto Vault". "Callisto Vault" allows users to (1) save a private time-stamped record of their assault, or (2) enter into the Callisto "matching escrow", a secure and private serial offender detection system. Users of the matching escrow enter information about their assailant, and if another user enters information about the same perpetrator, both users are connected to a pro bono attorney to help them decide what to do next. According to a 2022 report, a match triggers only emails to two lawyers, each with the contact details of one survivor but not naming the alleged perpetrator; the lawyers then contact the survivors to inform them of the match and offer assistance for any action they wish to take. Callisto Vault is available to individuals (students and employees) on a selection of college campuses, and offered only in the US. More information...
