#MeToo Reckoning

The #MeToo movement and subsequent tidal wave of accusations and lawsuits against powerful men like Harvey Weinstein and Bill Cosby forced society to reckon with the pervasiveness of sexual violence. Many also witnessed the risks of coming forward, how frequently perpetrators are serial offenders, and how rarely they face justice.

While many survivors felt more empowered, their options for coming forward safely remained limited. Filing a formal report was often retraumatizing, and relying on whisper networks exposed survivors and journalists to defamation lawsuits.

Our Solution

Callisto leverages cutting-edge technology to empower campus survivors, provide a safe alternative to reporting, and increase the likelihood that serial offenders will be held accountable. Our encrypted platform, Callisto Vault, allows survivors to create a timestamped record of their assault and/or match with others harmed by the same perpetrator.

Our Technology

  • Can be used whether or not a survivor chooses to report or disclose publicly

  • Helps survivors process their trauma and make informed decisions about if/how to proceed

  • Protects against defamation, as both survivor and perpetrator information is encrypted and secure

  • Safely connects survivors of serial offenders, increasing the likelihood that perpetrators will be held accountable

  • "Since that original match, I’ve learned about multiple other students on my campus who were harmed by the same perpetrator. Not a single one of us knew the behavior was serial...We had another trend in common. We each wanted to report, but couldn't do it alone. Thanks to Callisto, we weren't."

    Anonymous Matched Survivor

  • “Callisto was my safety net. I knew once I entered that system that one day I would find the person who made me less alone. And that was what I needed to feel whole again and to start healing.”

    Ray Epstein, Callisto Ambassador

  • "Callisto enables the survivors of sexual assault to do something unprecedented: they can discover if their abuser is a repeat offender without identifying themselves to the authorities or even identifying the name of the abuser. They have learned something useful, and possibly helpful, without having given anything away."

    The Guardian

  • "Representing campus survivors, I see how often perpetrators are serial offenders, and how hard it can be to come forward. Callisto's Matching System is game-changing innovation that empowers survivors and helps prevent perpetrators from evading justice."
