Our Responsibility

Justice, Equity, Diversity, and Inclusion

At Mammoth, we are committed to maintaining a supportive community for all employees. Our Employee Resource Groups (ERGs) provide allyship, enhance career development, and contribute to employees’ personal growth. They are a vital tool in our efforts to make JEDI a key component of Mammoth’s success. We have highly motivated groups (highlighted below) tasked with providing resources to individuals from different teams, with different interests, and with different identities. As we continue to expand, we will encourage collaboration between these groups to support a diversity of initiatives that celebrate, teach, and implement JEDI principles.

  • Team Unity, Socials and Culture (TUSC)

    Driving team unity and culture

    The Team Unity, Socials and Culture (TUSC) group at Mammoth aims to foster a collaborative cross-functional community and to support personal and professional growth for employees.

  • Womxn and Allies at Mammoth (WAM)

    Empowering womxn at Mammoth

    WAM leads efforts to empower womxn and allies and elevate them to their full potential at Mammoth and beyond.

  • Diversity as a driving force at Mammoth

    The core of our team

    Diversity powers everything we do at Mammoth. Our technology’s strength lies in the diversity of CRISPR systems, and our team’s strength lies in the diverse people and perspectives that guide us. Our ERGs, TUSC, and WAM are designed to ensure diverse people and perspectives shine.

Celebrating diverse scientists
