Antonia helped build one of the most iconic period brands in the world. In this episode, she takes us inside the real, messy, deeply human journey of launching Thinx: from her pink pajama shame moment at 13 to raising millions, writing her own patent, and co-founding a brand that changed the way we talk about periods.
But that’s only the first half of the story.
She opens up about what it actually felt like to raise money, negotiate with strategic partners, and sit in rooms where you slowly lose control of the brand you built. What happens when you and your co-founders don’t want the same future? What do you do when the investors are offering the deal of a lifetime?
