Company profile

researched Aug 2026

Mango Health is a San Francisco-based digital health company focused on medication management and patient engagement. Its enterprise platform uses mobile software to engage patients and improve rates of adherence to prescribed treatment regimens, and it works with healthcare organizations to help patients understand their medications, build healthier habits and improve outcomes.

The company's first consumer product is a mobile application, initially released on iPhone, that applies triggers and rewards drawn from social gaming to medication management. Features include daily reminders timed to a patient's dosing schedule, self-reporting of adherence (including photographing medication containers), a health journal for tracking exercise and daily activities, alerts about potential drug-drug interactions, and a social comparison element showing how a user's adherence compares with others. The team draws on backgrounds from Google, Castlight Health and mobile game company ngmoco, combining mobile software development with persuasive design.
