Our Products

In 2015, Callisto launched “Callisto Campus” to support college sexual assault survivors. It is currently available on 12 campuses across the United States. Survivors who visit their school's Callisto Campus site are 6x more likely to report their assault.

In 2020, Callisto will be launching a new product and offering, enabling us to serve more survivors and detect serial perpetrators across many institutions.

"It was hard to imagine coming forward in an immediately public way, but to start by chronicling what had occurred would have been a helpful and important first step."
― Anonymous, Male Survivor of Sexual Assault

The New Callisto

In 2020, Callisto will launch a new product. Similar to Callisto Campus, the new product will detect serial sexual offenders. In this new system, victims of serial offenders will be connected to an attorney.

This attorney will help survivors understand a wide range of options for taking action to protect their community (e.g. report to police, report to HR, report to the Title IX Coordinator, go public). They will also help victims of the same perpetrator share information with one another and coordinate their actions.

"I was raped during the first week of my freshman year, and I can't even count the number of people I know who have been sexually assaulted during their college career. I wish there would've been more education about sexual assault in general as well as reporting options and support services."
― Anonymous, Survivor of Sexual Assault

Callisto Campus

An estimated 20% of women, 7% of men, and 24% of trans and gender nonconforming students are sexually assaulted during their college career. An estimated 90% of sexual assaults are committed by repeat perpetrators. Over 85% of college survivors know their assailant, and less than 10% report to their school or the police.

Callisto Campus allows college sexual assault survivors to learn about their school's and police department's reporting channels, connect with local resources, create a record of their assault, or learn whether there are other victims of the same perpetrator. Callisto Campus is available on 12 college campuses.

Survivors who visit their school’s Callisto Campus website are six times more likely to report their assault and three times more likely to connect with medical or emotional resources. And 15% of survivors entering our matching system (see below) match with another victim of the same assailant, causing them to report simultaneously.

“Say we have 100 survivors on campus. There’s probably 80 different preferences for how they report their assault. Prior to Callisto, we had one option for all of them — and that was to come and talk to an administrator.”
