FOUNDER'S STORY

Why I Created GoZzzz

For almost 10 years, I could barely sleep. I tried medication, melatonin, meditation. Nothing truly worked.

Then I spent another 10 years studying the science of sleep — research by research, study by study. Walker, Huberman, Czeisler, Breus — I dove deep into every published finding.

GoZzzz is the program I wish I had found at the beginning of that journey.

José Nilton, Founder of GoZzzz

Today I sleep 7–8 hours on virtually every night. And you can too.
