William Fishenden

As a serial entrepreneur and co-founder of one of the UK's fastest-growing health food brands, William Fishenden sits at the intersection of food, performance, and business innovation. With a background spanning hospitality, e-commerce, and subscription DTC, William brings a practitioner's perspective to the topics shaping modern entrepreneurship, from DTC growth strategy and functional nutrition, to biohacking, longevity, and the future of health food. A self-confessed AI enthusiast, William is currently exploring how emerging technology can unlock scale across marketing, operations and retention.

William co-founded Prep Kitchen with a single conviction: that healthy eating should be effortless. What followed was a period of exceptional growth, with the business achieving 100% year-on-year revenue growth and recognition in the Sunday Times list of the UK's fastest-growing companies. Today Prep Kitchen serves over 20,000 active weekly subscribers with high-protein, ready-to-eat meals built around performance nutrition principles.

Before Prep Kitchen, William built and scaled a seven-figure Amazon business before a successful exit, and prior to that, ran his own restaurant, giving him an end-to-end perspective on food, consumer behavior, and commercial operations that few founders can claim.
