Spanx: $5,000, a pair of scissors, and no outside investors

What happened
Sara Blakely was selling fax machines door to door when, in 1998, she cut the feet off her pantyhose to get a smooth look under trousers. She put her $5,000 savings into developing the product, researched and wrote much of her patent herself, and persuaded a hosiery mill to make it.
She pitched a Neiman Marcus buyer by taking her into the bathroom to show the before-and-after. In 2000 Oprah Winfrey named Spanx one of her ‘Favorite Things’, and sales took off. Blakely kept full ownership and marketed through word of mouth and her own story rather than big advertising budgets.
Forbes named her the youngest self-made female billionaire in 2012. In 2021 Blackstone bought a majority stake in a deal valuing Spanx at about $1.2 billion.
