INTERVIEW | Make Money by Reinventing a Boring Industry, feat. Brynn MacLennan

from Travis Makes Money · host Travis Chappell

Brynn MacLennan is a serial entrepreneur and product designer who’s been building businesses since she was just 13 years old. With a background in product design and experience working alongside the dental industry, Brynn co-founded an innovative electric flosser designed to make oral care easier, more effective, and actually enjoyable. Her journey spans everything from launching a bounce house company as a teenager to buying and scaling a dental practice—and now disrupting a legacy industry with a modern, dentist-backed product. On this episode we talk about: Why most people floss incorrectly—and how that impacts dental health The process of designing and manufacturing a physical product from scratch Buying, scaling, and selling a dental practice The realities of launching via Kickstarter (and what she’d do differently) Building a multi-channel business across DTC, Amazon, and retail (including Target) Top 3 Takeaways Making a “boring” habit easier (like flossing) can unlock massive business opportunities—simplicity drives adoption. Big companies and internships can provide invaluable systems and process knowledge before starting your own business. Distribution is everything—success in DTC, Amazon, or retail each comes with unique challenges, and none are “set it and forget it.” Notable Quotes "If we made flossing easy and effective, people wouldn’t hate going to the dentist." "I know how to build a million-dollar company—but building a hundred-million-dollar company is a different game." "Entrepreneurship is constant ups and downs—just when you feel on top, something changes."
