In this episode of Chess Not Checkers, hosts Keith Riddle and Jordan Tampien sit down with Brynn MacLennan, CEO and co-founder of Slate, to talk about her journey building an electric flosser that makes oral care simple, effective, and dentist-approved.

Brynn shares the story of how Slate started, from early ideation in 2019 to launching the product in 2022, and the challenges of scaling a consumer product business. She dives into lessons learned about innovation, leadership, team culture, and navigating unexpected hurdles like COVID-19.

This conversation isn’t just about floss—it’s about creating products people actually use, leading with purpose, and turning ideas into businesses that last. Whether you’re an aspiring entrepreneur or just someone who hates flossing, Brynn’s insights are practical, inspiring, and surprisingly fun.
