The Digital Health Sandbox Rolling Grant program funds projects to test, validate and pilot innovative health tech solutions in sandbox environments. Companies with a Massachusetts presence may apply for grants up to $60,000 to fund a validation project with an organization in the Digital Health Sandbox Network. Applications are evaluated on the feasibility of the proposed project, the uniqueness of the company in the digital health market and the potential impact of the project on the applicant company, the state’s innovation economy, patients’ lives and health disparities.
The first step in applying for a grant is to contact a sandbox to determine if they can support your company. To identify and be introduced to potential sandbox partners, sign up to meet with a member of MeHI’s team during Sandbox Office Hours here. A signed letter of support from the applicant's selected sandbox is required as part of the application.
