867 Brynn MacLennan: Co-Founder & CEO of Slate Flosser

On today’s episode, we welcome Brynn MacLennan, Co-Founder and CEO of Slate Flosser — a women-led oral care company on a mission to transform flossing from an overlooked chore into one of the most important habits in preventive health. A product designer, entrepreneur, and mother of five, Brynn built Slate after recognizing that flossing wasn’t a motivation problem—it was a design problem. What started as a Kickstarter project evolved into a seven-figure company and the #1 dentist-recommended electric flosser on the market. In this episode, Brynn shares how purchasing a dental practice opened her eyes to the connection between oral health and overall health, and why she believes the mouth is one of the most overlooked gateways to longevity. We discuss the three-year journey of developing Slate’s patented 3-in-1 electric flosser, the challenges of disrupting a stagnant category, and how thoughtful product design can change consumer behavior. Brynn also opens up about scaling from a garage invention to a nationally recognized brand, building a women-led company culture, balancing entrepreneurship with raising five children, and why a simple 60-second daily habit can have a meaningful impact on long-term health outcomes. A must-listen for founders, product innovators, health enthusiasts, and anyone interested in prevention, behavior change, and building a brand that solves a real-world problem.   Are you interested in sponsoring and advertising on The Kara Goldin Show, which is now in the Top 1% of Entrepreneur podcasts in the world?
