Stellar Sleep is a digital health company specializing in sleep psychology, offering a mobile app designed to help users overcome insomnia and improve sleep quality. The company operates in the digital health market, targeting individuals suffering from sleep disorders, particularly insomnia. Stellar Sleep's business model revolves around a freemium app that provides a free sleep quiz to evaluate sleep quality and identify potential issues. The app then offers personalized, science-backed solutions to address these issues, with premium features available for a fee. Revenue is generated through in-app purchases and subscriptions. The company collaborates with renowned institutions like Harvard Medical School and Brigham and Women's Hospital, although these institutions do not directly endorse Stellar Sleep.
