Brynn MacLennan & Slate Flosser

In this episode of Read Receipt, Sean sits down with Brynn MacLennan, founder and CEO of Slate Flosser , the 3-in-1 electric flosser and flossing system invented by a dentist and approved by hygienists. Her pitch is simple: everyone knows they need to floss, and Slate just made it easy. Brynn has run companies since she was a kid, became a mom of five, and took over Slate the same month as its 2021 Kickstarter. She walks through launching in 147 Target doors this February, why the playbook that works online didn't work on a store shelf, and how 36% of people who buy a Slate Mini come back for the Pro within a month. She also gets into the hardest part of growing up as a founder: hiring a chief growth officer and letting the team move at their own speed. She also digs into why Slate keeps fulfillment in-house in Spokane, staffed by refugees, why Meta stopped being a money-making channel, and why TikTok doesn't fit a buyer who already invests in taking care of themselves. Plus what Amazon can take away in a week, what innovation costs in a device category, and the investor who said "don't follow up with me," then called three weeks later.
