About this episode

Matt and Mattie Sims discuss building Courier Socks, a brand for the Renaissance athlete, and share insights on bootstrapped growth and marketing strategies.

Matt and Mattie Sims are the co-founders of Courier Socks, a performance sock brand built for the Renaissance athlete — the person who isn't limited to just one sport. In this episode, we get into how a snapped achilles and a $10 sock sparked a product thesis, how five co-founders from world-class brands assembled into something that felt inevitable, and what it really looks like to build a bootstrapped brand without quitting your day job, without outside funding, and with a toddler in the mix. Topics covered: Building with five co-founders — why more wasn't messier, it was essential The Renaissance athlete — Courier's positioning and who they're actually building for The sock category opportunity — why performance socks have been left behind relative to footwear Bootstrapped growth and marketing — what's worked, what hasn't, and the myth of the breakthrough moment Lessons from Lululemon — what they carried out and what they left behind Links: Get 15% off your Courier Socks order by using this link .
