Marble Health

Founded in 2024, and based in New York, US, Marble Health operates as a health technology company that focuses on providing online mental health services for middle and high school students. Marble offers a virtual mental health care platform tailored for teens, school counselors, and their students. In October 2025, Marble Health raised USD 15. 5 million in Series A funding led by new investor Costanoa Ventures, with participation from returning investors Town Hall Ventures and Khosla Ventures.

The platform allows counselors to refer students with just a few clicks, ensuring they receive care within four days. Marble provides regular updates to counselors and collaborates with parents to ensure comprehensive support. The process includes an intake appointment to understand the student's needs, followed by group or individual therapy sessions. The platform also allows teens to connect through a referral from their school counselor.

After an intake appointment, teens can start group or individual therapy within one to two weeks. The company plans to utilize the October 2025 funding to expand access to critical mental health care in schools across the U. S. and grow its team to accelerate innovation and impact at scale.
