Sienna McCormick
Sienna McCormick is the co-founder and co-CEO of Create Wellness, the New York company that turned creatine - long stuck in the bodybuilder aisle - into a daily gummy. After six years at Goldman Sachs, she and her husband Dan bootstrapped the brand from their apartment in 2022, shipped the first creatine monohydrate gummy after more than twenty manufacturers said it could not be done, and have since sold north of 250 million of them. In March 2026 the company raised a $20 million Series B led by Alliance Consumer Growth, with the stated ambition of getting 100 million Americans onto daily creatine by 2030.
