Marble Health Raises $15.5M Series A to Expand School-Based Mental Health Services Nationwide

Marble Health has raised US$15.5 million in Series A funding, a move aimed at expanding its school-based mental‑health platform across the United States. The financing round was led by Costanoa Ventures with participation from Town Hall Ventures and Khosla Ventures.

Founded in 2023 by former leaders of a major adult‑therapy provider, Marble Health works by partnering directly with schools. School counselors refer students in need of support, and Marble connects them with licensed therapists — offering virtual or in‑person therapy covered by insurance (including Medicaid) so that families and schools pay nothing upfront. Since its launch in New York, the company says it has already facilitated over 15,000 therapy sessions for children and families who otherwise would struggle to access care.

A core differentiator of Marble’s model is its tech‑stack tailored for youth mental health: therapists have access to an AI-assisted scribe and a proprietary electronic health record (EHR) system, which together streamline documentation and billing — especially when dealing with Medicaid. This infrastructure lowers administrative burdens and makes it easier for clinicians to participate in public insurance networks. Marble also offers both individual and group therapy sessions, enabling clinicians to serve more students while maintaining quality care.

With this new infusion of capital, Marble plans to expand into more school districts across the U.S., ramp up hiring, and grow its therapist network. The company aims to launch in additional states — particularly in regions where youth populations are high and mental‑health resources scarce — and to increase the number of both virtual and in‑person therapy slots.

Investors’ decision to back Marble underscores growing confidence in mental‑health companies blending clinical care with tech-enabled delivery models. As adolescence mental‑health challenges rise nationally — with anecdotes and data showing growing rates of anxiety, depression, and suicide among teens — many traditional mental‑health providers remain overwhelmed or under-resourced. By focusing on affordability, insurance-based reimbursement, and integration with school systems, Marble seeks to fill a critical gap and make therapy accessible to underserved communities.

The involvement of Costanoa Ventures, Town Hall Ventures, and Khosla Ventures not only brings investment capital, but also strategic support and access to deep venture networks, helping Marble scale its operations rapidly. With strong early adoption, a focused and impactful mission, and backing from reputable investors, Marble Health appears poised to significantly expand access to mental‑health care for young people nationwide — hoping to serve thousands more students who might otherwise go without timely support.
