Sequel Tampons—founded by Stanford-trained engineers Amanda Calabrese and Greta Meyer—has forged a headline-grabbing alliance with the Indiana Fever, the WNBA franchise now synonymous with breakout sensation Caitlin Clark. The partnership unites two fast-rising forces: an inventive startup redesigning feminine care for the first time in eight decades and a basketball team reinvented by fresh leadership and star power.
Under new general manager and COO Amber Cox and head coach Stephanie White, the Fever surrounded Clark, 2023 top pick Aaliyah Boston, and veteran sharpshooter Kelsey Mitchell with seasoned stars DeWanna Bonner, Sophie Cunningham, Sydney Colson, and Natasha Howard—an overhaul that already delivered silverware with a dominant Commissioner’s Cup victory over the Minnesota Lynx. The triumph, achieved without Clark on the floor, signaled the franchise’s depth and validated its bold offseason gambles.
Sequel’s agreement brings its patented tampons into every women’s restroom at Gainbridge Fieldhouse, letting fans sample the product that athletes trust in pressure-packed moments. A showcase “Sequel Game” on July 13—pitting Clark against 2025 first overall pick Paige Bueckers of the Dallas Wings—will feature in-arena activations, surprise giveaways, and complimentary take-home packs, all staged one week before Indianapolis hosts the 2025 WNBA All-Star festivities.
The startup’s rise traces back to a simple insight: seven in ten women doubt their tampon’s reliability. By re-engineering shape and flow mechanics, Sequel earned 11 U.S. patents and FDA clearance in 2023, then secured more than $8 million in venture backing to scale production. Direct-to-consumer subscriptions, an online storefront, and TikTok Shop virality—where weekly videos surpass six-figure views and one clip topped 4.5 million—have turned the brand into a digital standout.
Momentum has carried Sequel into exclusive agreements with Stanford Athletics, Washington D.C.’s Audi Field, and now one of the world’s most watched women’s teams. Calabrese calls the Fever partnership “transformative” for the business, viewing WNBA fans—active, inspired, and connected to female role models—as the perfect audience for a product built to perform when every second counts.
