She Left Private Equity to Rethink Everything We Know About Yogurt and Gut Health with Kiki Couchman, Co-Founder of Sour Milk

Most people who leave high-finance careers to start a food company have a moment — one experience, one realization, one thing they couldn’t unsee — that made going back feel impossible.For Kiki Couchman, that moment was gut health. Not as a trend. As a personal obsession that turned into a product gap she couldn’t stop thinking about.In this episode of In Alignment, Kiki shares the full story of how she went from private equity to co-founding Sour Milk — a next-generation probiotic yogurt brand built on real fermentation, radical transparency, and a community of people who actually care what goes into their food.This is not a tidy founder story. It is honest about the uncertainty, the bootstrapping, the decisions made in the gray area, and what it actually takes to build something people trust in a market full of products that overpromise and underdeliver.What we cover in this episode:Kiki’s journey from private equity to food startup — what she saw in the market, what was missing, and why she bet on itThe science behind Sour Milk and what most people still get wrong about probioticsWhat it actually takes to build a brand in the CPG space — sourcing, manufacturing, quality control, and why product integrity has to come before fundraisingHow Kiki and her co-founder have built a loyal community through radical transparency — building in public, stories, AMAs, and showing the real process not just the highlight reelDecision-making in uncertainty — how to build confidence by starting to act in the gray area instead of waiting for certainty that never comesWhy authenticity is not a branding strategy, it is a survival strategy — especially for early-stage founders who don’t have a marketing budgetA few things that stuck with us:“Every year helps build on the momentum.” — on why staying in the game longer than feels comfortable is often the entire strategy.“Your gut produces natural GLP-1s.” — one of the most fascinating moments in the episode and a reminder that the body already knows what to do when you give it the right inputs.If this episode resonated:Follow Kiki and the Sourmilk journey And if you want to try Sour Milk — find them at [sourmlk.com] (add correct link).
