Marble is building an operating system for youth mental health by connecting schools, therapists, and health plans on a single platform. The company addresses a critical crisis: 1 in 10 teens attempted suicide last year, driven largely by lack of access to quality, affordable care. Marble partners with school counselors to connect students to licensed therapists through existing insurance coverage, eliminating waitlists.
