I love self work. I love new ways of doing things.  That made me an early adopter of Sayana, Headspace, Balance and others. And every time it fits me, I feel the need to spread these health products to everyone around me. 

A few months ago, I designed and built most of this list in 24h at the Webflow Global Maker Day. In March, I revamped it and changed the name, added more tools. I can now officially publish "breakthru" :)   

My goal is to share what these awesome companies and individuals have been building to help us all feel better, track our mood, resolve our traumas, through those awesome tools.
