Marble Secures $15.5M to Expand School-Based Mental Health Care Nationwide

Marble, a youth mental health company focused on building infrastructure for a modern teen mental health system, has secured $15.5 million in Series A funding. The round was led by Costanoa Ventures, with participation from Town Hall Ventures and Khosla Ventures. The company will use the capital to expand its school-based programs, extend access to mental health services for students across the U.S., and accelerate product innovation.

The funding comes amid escalating concerns about the national youth mental health crisis. According to the CDC, one in ten teenagers attempted suicide in the past year, while rates of anxiety, depression, and social isolation continue to rise. Access to care remains a critical barrier—especially for Medicaid-covered families—where long wait times at community clinics often leave students without timely support. School counselors, frequently the first line of defense, face average caseloads of 385 students, limiting their ability to respond effectively.

Marble was founded by Jake Sussman and Dan Ross, former co-founders of Headway, to directly address these systemic gaps. By partnering with schools, Marble identifies students in need and connects them with licensed therapists. Since its 2024 launch in New York, the company has facilitated more than 15,000 therapy sessions for children and families who might otherwise lack access. Its model integrates with both Medicaid and commercial insurance networks to ensure equitable service delivery.

CEO Jake Sussman, a former teacher, described the company’s mission as deeply personal. “I saw students in crisis left waiting for help, while school counselors scrambled to find support that just wasn’t there. We built Marble to close that gap—because kids shouldn’t have to wait for help, and schools shouldn’t have to go it alone,” he said.

Marble’s platform combines clinical access with technology designed to reduce administrative challenges common in public insurance systems. Its AI Scribe tool and proprietary electronic health record streamline Medicaid participation for therapists, easing documentation and billing processes. Additionally, the company’s group therapy programs expand clinician capacity by allowing therapists to support multiple students simultaneously while maintaining quality of care.

Through its hybrid approach—integrating technology, school partnerships, and payer collaboration—Marble aims to redefine how youth mental health services are delivered at scale.
