Marble Secures $15.5 Million Series A to Enhance Teen Mental Health Care Access

Marble, a pioneering company focused on improving mental health solutions for youth, has announced it successfully secured $15.5 million in Series A funding. This significant investment, led by Costanoa along with participation from Town Hall Ventures and Khosla Ventures, is aimed at expanding access to vital mental health services in schools across the United States. With growing mental health challenges among teenagers, Marble’s mission is more critical than ever.

Recent statistics from the CDC reveal alarming trends in youth mental health, indicating that 1 in 10 teenagers attempted suicide within the last year. Rates of anxiety and depression are escalating, yet families often encounter major obstacles when seeking care. Half of American youth are enrolled in Medicaid, and for many of them, getting appointments at community clinics often means enduring lengthy waiting periods that can last many months or even years. School counselors represent the first line of support for many students, but they are frequently overwhelmed, handling case loads averaging an astonishing 385 students each.

Personal Stories of Struggle

One poignant account from a Marble client highlights the pressing need for comprehensive mental health support. A parent shared her desperate attempts to find a therapist for her son, who was covered by Medicaid. After extensive searching, she was unable to find a suitable provider. Feeling increasingly helpless, she observed her son decline emotionally. His condition deteriorated to the point where he refused to communicate with her altogether, amplifying her worries.

Founded by Jake Sussman and Dan Ross, former co-founders of Headway—the country’s leading provider of mental health services for adults—Marble collaborates directly with schools to pinpoint students in crisis and connect them with licensed therapists efficiently. Since launching in New York, the company has facilitated over 15,000 therapy sessions for children and families who would typically lack access to adequate care.

By embedding their program within schools and engaging directly with both Medicaid and private insurance providers, Marble effectively supplies students with evidence-based therapeutic options, particularly benefiting those relying on public insurance.

Addressing the Mental Health Crisis

Jake Sussman, CEO of Marble, shared insights from his teaching experience in a low-income Brooklyn charter school, where he witnessed students desperate for help waiting unproductively for care as counselors struggled to secure resources. “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 emphasized.

What differentiates Marble from traditional mental health solutions is its integrated collaborative approach. The platform allows counselors, parents, and therapists to exchange insights in real time, establishing a unified support system. Moreover, Marble alleviates the administrative burden associated with Medicaid by providing innovative tools like AI scribes and proprietary electronic health records (EHR) for therapists, facilitating greater participation in Medicaid networks and vastly increasing accessibility.

The company has also introduced group therapy programs that optimize clinician capacity, allowing therapists to engage with multiple students simultaneously without sacrificing quality of care.

Innovative Approach to Support Schools

“Many schools wish to support their students’ mental health, yet they often operate with limited resources,” said Amy Cheetham, Partner at Costanoa Ventures. “Marble’s model stands out because it provides essential services at no cost to schools, ensuring timely and high-quality care for students. That level of access shouldn’t be exceptional, and we support Marble's mission to make it mainstream.”

As Marble looks to extend its reach across the nation, it simultaneously develops a robust data advantage, blending insights from therapists, schools, and family interactions to enhance the precision, personalization, and efficacy of its mental health products.
