Daniel Yeh

Daniel is primarily responsible for business development, investor relations, and strategic vision. He has been swimming competitively since the age of 7 at Swim Atlanta, Dynamo, and eventually Georgia Tech. Always pushing himself inside and outside the pool and seeking a performance edge, he became curious about the role supplements played and set out to educate himself. Along the way he stumbled onto an evidence based approach to supplementation. Eyes opened. What started as scratching his own itch and mixing supplements in bulk resulted in co-founding Citadel Nutrition. 


In addition to starting Citadel Nutrition he is a founding partner at the CN Training Center, a training facility for top level athletes and powerlifters, and co-founder of FitGenie, an artificial intelligence solution to dieting and nutrition developed in conjunction with the Georgia Tech Venture Lab. He is also managing partner at Super Heavy Ventures, a venture capital company with an emphasis on companies in the fitness and health sector.
