Founding Product Manager @ AI Identity Cybersecurity Venture, Berlin

This is an Atlantic portfolio venture. About the Venture We are building a cyber risk platform that helps enterprises understand, measure, and reduce identity risk at scale. We turn complex identity and security data into clear, actionable insights that CISOs and CTOs can trust. Founded by experienced cybersecurity leaders with backgrounds in Israeli intelligence, we are recently funded and building from scratch. The problem is real, the market is large, and we are moving quickly. About the Role This is a founding product hire.
