Mightier

Bioresponsive games for pediatric emotional health

Overview

Mightier provides a digital health platform that helps children aged 6-14 build emotional regulation via bioresponsive games paired with a heart-rate monitor. In gameplay, rising heart rate makes games harder, motivating kids to employ calming techniques to lower their heart rate and continue. The platform is offered as family subscriptions and also through B2B partnerships with employers and health plans, supported by clinical research from Boston Children's Hospital and Harvard Medical School. Its goal is to give kids and families a practical, evidence-based tool to reduce behavioral challenges and parental stress by improving emotional regulation.
