Second Nature was founded by Chris and Mike in 2015. They met while working as advisors to the NHS, where they saw the impact of lifestyle diseases on both people and health services first-hand.

They realized the real challenges of living a healthy lifestyle weren't being solved. They believed there had to be a better way to make healthy living the default. They quit their jobs and used science and behavior change to build Second Nature.
