Callisto is a national nonprofit that is fighting to end serial sexual assault...one match at a time. Our revolutionary, encrypted Matching System enables campus survivors to safely find out if their perpetrator harmed others...without forcing them to report or come forward publicly. 

On April 24th, the Day of Reckoning, join us to ensure that as many survivors as possible know about and can use Callisto. Whether you participate by entering into Matching, supporting a loved one, spreading the word so more survivors know Callisto exists, or donating to expand access beyond college campuses, you are helping shine light into the darkness, so more survivors can find their way out, and so perpetrators can no longer hide.
