Callisto is a non-profit organization that leverages technology to combat sexual assault and support survivors. They create tools that allow individuals to securely and confidentially document their experiences, understand their reporting options, and, if they choose, connect with others who may have been assaulted by the same perpetrator. Their primary focus is on empowering survivors by giving them control over their information and decisions, aiming to increase reporting rates and identify repeat offenders, particularly within college campuses and professional organizations.
Administrative hub, strategic planning, and operational coordination for a distributed team. Serves as the official registered address.
The listed address is part of a modern office complex, likely serving as a registered agent or flexible office space rather than a large, traditional corporate headquarters, reflecting their agile and potentially remote-first operational model.
As a mission-driven non-profit focused on sensitive issues, Callisto's work culture likely emphasizes empathy, collaboration, innovation, and a strong commitment to survivor-centric principles. Team members are passionate about social impact and leveraging technology for good.
The administrative base in California places Callisto within a major tech and social innovation ecosystem, facilitating partnerships and access to talent. However, its impact is national through its digital platform.
Callisto's platform and services are primarily focused on institutions within the United States, particularly colleges, universities, and some professional organizations. While their digital tools can technically be accessed globally, their direct partnerships and support systems are currently U.S.-centric. Their impact is through the adoption of their technology by these partner institutions.
