And what if we told you there was a mushroom that could change that? Mainstream beverages often fall into two camps: sugary drinks loaded with additives or plain waters that do little more than hydrate. [Matt Martin](https://www.linkedin.com/in/matthew-martin-38671243/?originalSubdomain=uk) and [Dan D’Souza](https://www.linkedin.com/in/dan-d-souza/) are mixing it up with a lion’s mane-based functional soda, helping energize buyers by fueling their focus, boosting gut health and providing a pour of natural vitamins. Developed with the help of their cider-making friends (the founders of Cranes), [Muush](https://muush.co/?srsltid=AfmBOoq6WpdYsafQ9OPbiXP7ZuseEAfhKbMrdDO_Qj5WNrai3EsxE8_D) introduces mushrooms, without compromising on flavor, fun or nutrition. Join SeedLegals CEO[Anthony Rose](https://seedlegals.com/us/resources/author/anthony/?nr=1) in this Founder Interview where he chats with Matt about creating a new category of drinks, built for adults and children and kept cold in a 120-liter fridge from the trunk of a blue vintage Rolls-Royce. ## **Key takeaways** ### **The problem with mainstream drinks** - Most soft drinks fall into extremes. They’re either packed with refined sugar and additives or plain hydration with little nutritional benefit. - Artificial sweeteners, though marketed as ‘healthy’, can trick the body into craving more sugar, contributing to overeating and obesity. - The market lacked a balanced, genuinely functional drink that tasted good *and* delivered real health benefits. ### **Muush’s solution** - Muush introduces a lion’s mane mushroom-based functional soda, blending flavour and well-being in one bottle. - Each can is low in sugar, high in fiber, and enriched with vitamins A, D3, and C, so they’re designed to support brain function, gut health, and sustained energy. - By producing in-house with help from cider-making friends at Cranes, the team saved months of development time and thousands in production costs while keeping full creative control. ### **Traction and growth** - Muush is already stocked in around 70 locations across London, with growing presence in independent stores and marketplaces like *Our Deli* and *Village Whole Foods*. - The team’s signature bright blue Rolls-Royce fridge car has become a playful part of their brand story, driving both awareness and retailer support. - With a live online store and Amazon presence, Muush is now scaling up and securing new partnerships to bring its ‘good-for-you’ soda to a wider audience. ##### SeedLegals newsletter ### Connect with fascinating founders Sign up to our newsletter and get the best of SeedLegals events delivered directly to your inbox Stay ahead with the SeedLegals newsletter Get event invites and hot-off-the-press content straight to your inbox [Subscribe](https://seedlegals.com/us/newsletters/) ## Related posts [6 min read How to spot the right moment to flip from LLC to C corp Not sure whether to flip from LLC to C corp?
