Facebook Restricted Flex Ads as Sexual Content; Flex Leads 88% of US Category
Flex challenged Facebook ad restrictions that labeled menstrual-disc and cup content “sexual,” after reaching Sheryl Sandberg through an investor connection. Flex fought for equal ad language and visuals across platforms, then grew into a top-selling U.S. menstrual disc and cup brand, holding 88% dollar share, raising $20 million, and reporting profitability and double-digit growth over three years.
