Overview
Big Health is described as a digital therapeutics company. Its official website presents fully digital solutions for common mental health conditions, including digital CBT for insomnia and anxiety, offered to health systems and providers, health plans, and employers. The company states its mission is to help millions back to good mental health, combining clinical insight with design and technology, and cites peer-reviewed research and randomized controlled trials.
History
The idea for Big Health was born when co-founder Peter Hames had trouble getting anything other than medication for his insomnia. He discovered Dr. Colin Espie's book on cognitive behavioral therapy (CBT) for insomnia. The techniques he learned from the book resolved his sleep issues, and he realized what had worked for him could work for millions. Dr. Espie then became Peter's co-founder, and together they created Big Health and its mission: to help millions back to good mental health.
