back to good mental health

Committed to improving mental health with safe, effective, and accessible solutions for everyone.

Our path to better mental health

Big Health was founded after co-founder Peter Hames struggled to find a solution for his insomnia beyond medication. After discovering Dr. Colin Espie’s book on cognitive behavioral therapy (CBT), Peter realised this approach could help millions. Today, we’re combining clinical expertise with innovative design and technology, backed by rigorous research, to transform mental health care.
