About Fay At Fay, our mission is to make nutrition a foundational pillar of preventative care, improving outcomes, accessibility, and affordability at scale. We're building AI-powered infrastructure to transform preventative healthcare. Think that's bold? We're just getting started. Today, Fay is a three-sided marketplace connecting providers, patients, and payers to revolutionize preventative care delivery. Our b2b2c business-in-a-box solution empowers dietitians to deliver high-quality, affordable nutrition care, helps patients take control of their health, and enables payers to build healthier member populations. Nutrition is our starting point, not the finish line. The platform we're building will expand into new areas of preventative health and wellness as we grow. We're proud to be one of the fastest-growing companies in healthtech, backed by category-defining investors like General Catalyst, Forerunner, 1984, and Goldman Sachs.
