Jennifer Sey

Jennifer Sey is an American author, filmmaker, business executive, and retired National Champion gymnast. A seven-time U.S. Women’s National Team member, she won the 1986 U.S. All-Around National Championship and was named U.S. Olympic Committee Athlete of the Year. In 2008, she became the first gymnast to speak out about abuse in the sport through her memoir Chalked Up, later a New York Times e-book bestseller. She went on to produce the Emmy Award–winning Netflix documentary Athlete A (2020), which exposed Larry Nassar’s crimes and systemic abuse in gymnastics.

Sey spent over two decades at Levi Strauss & Co., rising to Chief Marketing Officer and Brand President. She was named one of Billboard’s Most Powerful People in Music and Fashion (2016) and appeared on Forbes’ Most Influential CMOs list in 2019 and 2020. In 2020, she stood alone among corporate executives in publicly opposing school closures during the pandemic. Her second book, Levi’s Unbuttoned, recounts her battle against corporate and cultural pressures to advocate for children. In 2022, Sey resigned from Levi’s. 

She is now founder and CEO of XX-XY Athletics, the pro-woman athletic brand -- the first and only to stand up for women's sports and fair competition.
