Headquartered in Boston, Mass., Nix is led by Founder and CEO Meridith Cass, a graduate of Harvard Business School, former VC, collegiate athlete, and 9-time marathoner. Cass developed the Hydration Biosensor after suffering from hyponatremia (often referred to as “over hydration”) during the Boston Marathon. In her research pursuits, and a desire to unlock more of her own personal health and wellness data, she discovered the void of options and solutions available for hydration monitoring.
