About Us

Hi, I’m Cade Spector, founder & CEO of GreySun Technologies. I founded this company and invented the GreyBand in honor of my older brother Grey, who took his life amid battles with substance-misuse disorders. It is my hope and belief that the GreyBand can and will help others like him, and families like ours.
