Company Overview

Mightier is a digital health company that provides a bioresponsive video game platform designed to help children build emotional regulation. Developed at Boston Children's Hospital and Harvard Medical School, the program utilizes a heart rate monitor that adjusts game difficulty in real-time, enabling children to learn calming techniques. The platform, aimed at children aged 6-14, addresses challenges such as anxiety, ADHD, and anger. The company originated as a research program, became an independent entity named Neuromotion Labs in 2014, and later rebranded its product to Mightier in 2018.
