Meet Feisty: the world’s first plant-powered protein soda.

Hate chalky protein shakes? Imagine if your favourite fruity soda had the protein of 2 eggs (no friggin’ whey). Founded by a scientist mother–daughter team, Feisty is fizzing up the $30B protein RTD industry with the world’s first soda powered by complete plant-based protein and a patent-pending formula. Just like a soda, clear, refreshing, and made for everyone (not just gym bros). Top up your protein whenever, wherever. 

✨ What makes us different:
• First to market with protein soda, the next wave in better-for-you soda

• Patent-pending formula ensuring clarity, stability & taste
• Clean label: complete plant-based protein, allergen-free, no added sugar, low calorie, caffeine free.
