In this episode, we speak with Richard and Rachael Prentice, the husband-and-wife co-founders of Rise and Plunge, Malaysia’s first dedicated contrast therapy spa offering private, Scandinavian-inspired experiences combining infrared saunas and cold plunges. We explore their journey from corporate careers to entrepreneurship, the science behind contrast therapy, and how they’re working to make cold plunge and sauna therapy more accessible at home. Plus, we'll also dive into how they scaled from DIY ice baths to a seven-figure wellness business, and what’s next for this ambitious duo.
