    About Callisto:

    Callisto is a San Francisco-based nonprofit organization that creates technology to combat sexual assault, empower survivors, and advance justice. Specifically, we create websites that detect repeat sexual assailants and make it easier for sexual assault survivors to report. We are funded by earned revenue from partnering institutions and philanthropic supporters, including Google.org, Y Combinator, Greylock Partners, and the Skoll Foundation.

    We are a small but powerful team, united in the belief that we can create a more just world. The culture around us is changing rapidly and the demand for Callisto has never been greater. We will soon expand to address sexual assault and professional sexual coercion in multiple industries, connecting victims of the same predator to each other and with legal support.

    Our Values:

    As a tech nonprofit working in the social justice space, we focus on three core values to drive our mission:

    1. Survivor Centric: Our mission is to support survivors by making the reporting process a safe, easy, and empowering experience. This means we are highly focused on protecting their data, designing trauma-informed UX, and ensuring high quality control.
    2. Truth Seeking: We’re all about the impact. We make decisions through grounded, logical, data-driven arguments. We value a culture of humility where we can own our mistakes and learn from them.
    3. Systems Focused: We understand that social justice is complex and requires sophisticated solutions. We see the big picture in order to solve audacious and impactful problems.
