The Sequel Story


Our Purpose

To create a world where no woman is sidelined by her period.

Sequel started with a white lacrosse skirt

While on the Stanford lacrosse team, I turned to a teammate and asked the question every woman knows: “Can you check me?”

My co-founder, Amanda, knew the feeling. After nearly a decade competing on the U.S. National Team in lifesaving, she had experienced the need for a better tampon competing in a bathing suit where there is nowhere to hide a leak. 

We were studying product design at Stanford University, where we trained to find real problems and engineer better solutions. We realized the problem wasn’t us. It was the tampon.


THE tampon we wish we had

That realization led to a simple question: Why do tampons fail before they’re full? Five and a half years of research, engineering, and testing led to the Sequel Spiral™ Tampon - a patented design that rethinks how a tampon absorbs from the outside in. 

We achieved FDA 510(k) clearance in 2023, and have since earned the trust of athletes at the highest levels of competition, from the Indiana Fever to Olympic and professional athletes. 

Today, Sequel is bringing that same standard of performance and reliability to women everywhere. We created the tampon we wished we had on game day.
