Marble Health, a youth-focused mental health company building infrastructure for a modernized school-based care system, has raised $15.5 million in Series A funding to expand access to therapy for students nationwide. The round was led by Costanoa Ventures, with additional participation from Town Hall Ventures and Khosla Ventures.
The funding will be used to scale Marble’s operations in schools across the United States, grow its team, and advance the company’s technology platform aimed at closing critical gaps in youth mental health care. And this announcement comes at a time when youth mental health challenges are escalating nationwide.
Marble addresses systemic barriers that prevent many children and adolescents from receiving timely, affordable mental health care. Nearly half of American youth are enrolled in Medicaid, yet families often face months-long waitlists at community clinics. School counselors, frequently the first responders to mental health crises, are stretched thin, with an average caseload exceeding 380 students per counselor.
Founded by Jake Sussman and Dan Ross, who are previously co-founders of Headway, the largest adult mental health network in the U.S., Marble partners directly with schools to identify students in need and connect them with licensed therapists. Since its launch in New York last year, the company has facilitated over 15,000 therapy sessions for children and families who might otherwise have gone without care.
By embedding within school systems and collaborating with both Medicaid and commercial payers, Marble ensures equitable access to evidence-based therapy at no cost to schools. The company’s platform also integrates real-time collaboration among therapists, counselors, and parents, creating a unified ecosystem of support for each student.
Marble’s technology streamlines the administrative challenges that often deter clinicians from participating in Medicaid networks. Its AI-powered tools, including an automated scribe and proprietary electronic health record (EHR) platform, reduce paperwork and improve efficiency, allowing more therapists to deliver care to underserved populations. The company also offers group therapy programs designed to maximize therapist capacity without compromising care quality.
The Series A funding will accelerate Marble’s national rollout, enabling the company to reach more school districts and strengthen its partnerships with public and private payers. As it grows, Marble is also building a data-driven foundation to enhance the precision and effectiveness of its clinical products. By combining insights from schools, therapists, and families, the company aims to refine its programs and improve student outcomes continuously.
KEY QUOTES:
“In my time teaching at a low-income charter school in Brooklyn, 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.”
Jake Sussman, CEO and Co-Founder of Marble Health
“Most schools want to support their students’ mental health, but they’re stretched thin and often can’t afford to bring in help. What stood out about Marble is that they’ve built a model where schools don’t have to pay a dime—and still get high-quality, timely care for their students. That kind of access shouldn’t be rare, and we backed Marble because they’re making it possible at scale.”
Amy Cheetham, Partner at Costanoa Ventures
“I tried literally everything I could to help my son, but I couldn’t make it happen. I searched far and wide for a therapist who accepted his Medicaid plan, but found none. The school couldn’t help me either, and my son just got worse and worse. He eventually stopped speaking to me entirely, and I grew more and more concerned about his well-being.”
