Welcome back to the Duck Pond Podcast, where we bring on founders, creatives, and brilliant minds to get behind the scenes on how to bring a product onto store shelves, covering branding, marketing, packaging, and the hard stuff in between.

Today we’re featuring Caroline Brain, founder of Kif Nature’s Soda, a fermented kefir-style soda built for gut health. Caroline turned her own struggles with brain fog, fatigue, hormonal imbalance, and more into a mission: craft a probiotic beverage that’s low sugar, full of real ingredients, and approachable. Kif now delivers 12B+ live probiotics per can, with no artificial sweeteners.

We’ll dive into:

• How Kif positions itself in the functional soda & probiotic space

• The rebrand from kefir water to Nature’s Soda and what drove that change

• What it takes to grow a beverage brand built on fermentation, community, and trust

• Caroline's Gut Hut community and how she's bridging the gap between consumers

• Marketing, distribution, and packaging lessons from a gut-healing brand

✨ Learn how Kif is redefining soda—making it gut-friendly, functional, and fun.
