Amanda Calabrese was a middle schooler at a swim meet when she got her period for the first time. Her team captain told her to figure it out in thirty minutes or she was off the relay. That moment stuck with her all the way to Stanford, where she met her future co-founder Greta Meyer and started sketching what would become Sequel, the first tampon redesign in nearly a hundred years. On this episode of She Pivots, Amanda talks about the four-year fight to get a tiny piece of cotton past the FDA, why she treats the tampon as game-day equipment rather than something to whisper about, and how Sequel landed in locker rooms from middle schools to Audi Field, Yankees Stadium, and the Indiana Fever. Now a nine-time champion turned product design engineer, Amanda is on a mission to change how period care is talked about in sports and in every space where women show up to compete.
