Spanx
Sara Blakely turned $5,000 and a pair of scissors into a $1.2 billion shapewear company. She owned 100% for 21 years without taking a single dollar of outside investment.
Sara Blakely invested $5,000 of her savings from selling fax machines door to door, wrote her own patent using a textbook from Barnes & Noble, and built Spanx into a company valued at $1.2 billion when Blackstone acquired a majority stake in October 2021. She never took a single dollar of outside investment for the first 21 years, which is essentially unheard of for a company generating over $250 million in annual revenue.
Blakely owned 100% of Spanx from 2000 to 2021, making her the youngest self-made female billionaire on the Forbes list in 2012 at age 41. After the Blackstone deal, she retained a significant minority stake and her net worth is estimated at $1.1 to $1.5 billion, built entirely from a single product idea she kept secret from her friends and family for a full year because she was afraid they would talk her out of it.

The Story
Sara Blakely had a pair of white pants hanging in her closet for eight months because she could not find undergarments that looked smooth underneath them. In 1998, while getting ready for a party, she cut the feet off a pair of control-top pantyhose, wore them under the white pants, and realized that the product she wanted did not exist. She was 27 years old, had a communications degree from Florida State University, and had spent the previous seven years selling fax machines door to door for a company called Danka, where she was promoted to national sales trainer by age 25.
She invested her entire savings of $5,000 and spent the next two years developing the product in secret, telling no one about the idea for a full year. To save the $3,000 to $5,000 that patent attorneys quoted her, she bought a textbook on patents and trademarks at Barnes & Noble and wrote the application herself, with her mother providing the prototype sketches. She cold-called hosiery mills across North Carolina and was rejected by every single one, with some laughing at her on the phone. She took a week off from selling fax machines, drove to the mills in person carrying a red backpack she had kept since college, and was turned away again. Two weeks later, a mill owner in Asheboro, North Carolina called back because his two daughters had convinced him that the idea was worth making.
Getting into retail required the same approach. The Neiman Marcus buying office gave her ten minutes if she flew herself to Dallas. Five minutes into the pitch, she could tell it was not landing, so she asked the buyer to come to the bathroom, where she modeled her white pants with and without Spanx. The buyer placed an order for seven stores on the spot, and Bloomingdale’s, Saks, and Bergdorf Goodman followed shortly after.
The brand name came from her belief that the “k” sound was commercially lucky, based on the success of Kodak and Coca-Cola. She changed “Spanks” to “Spanx” at the last minute. In November 2000, Oprah Winfrey named Spanx one of her Favorite Things on national television after Sara sent a gift basket with prototypes and a handwritten note to Oprah’s stylist Andre Walker. First-year revenue hit $4 million, and by the following year she had sold 8,000 units in under six minutes during her QVC debut.
The Strategy
Twenty-one years without a single investor
From 2000 to 2021, Blakely ran Spanx entirely on revenue and her original $5,000 investment. She never took venture capital, angel funding, or bank loans, and she maintained 100% ownership the entire time. By 2014, the company was generating over $250 million in annual revenue with estimated net profit margins of 20%. For context, Glossier raised $265 million in venture capital before reaching $200 million in revenue, and Rhode sold to e.l.f. after three years. Blakely held on for two decades because she could, and the math made it possible because shapewear margins are exceptionally high and the category had no meaningful competition when she entered it.
Zero advertising for sixteen years
Spanx spent nothing on traditional advertising for the first sixteen years of the company. All growth came from word of mouth, celebrity gifting, in-store demonstrations where Sara modeled the product herself, and earned media. She sent full gift baskets to celebrity stylists and let the product speak for itself. Her philosophy was that word of mouth and press coverage were more believable than paid ads, and the Oprah endorsement in the first year proved her right.
Department stores first, then everywhere
Spanx launched through high-end department stores because that was where the target customer already shopped for undergarments. Neiman Marcus came first, followed by Bloomingdale’s, Saks, and Bergdorf Goodman, and the prestige placement gave the brand credibility that took years for competitors to replicate. She later expanded to QVC, Nordstrom, and eventually Target through a sub-brand called ASSETS by Spanx, which allowed her to reach a mass-market customer without diluting the main brand’s positioning.
Two hundred patents and the Faux Leather Leggings
Spanx holds over 200 patents, and the company continuously expanded from the original footless pantyhose into bras, leggings, activewear, denim, and swimwear. The Faux Leather Leggings, launched in 2015, generated $50 million in first-year sales and became the product that introduced Spanx to a generation of women who had never bought shapewear, proving that the brand could sell fashion, not correction.

The Blackstone deal: In October 2021, Blackstone acquired a majority stake at a $1.2 billion valuation. The deal was brokered by an all-female Blackstone team led by managing director Ann Chung, and the resulting board of directors was made entirely female. Co-investors included Oprah Winfrey, Reese Witherspoon, and Whitney Wolfe Herd. Sara remained as executive chairwoman and retained significant equity.
The celebration: When the deal closed, Blakely gave every one of her approximately 500 employees two first-class plane tickets to anywhere in the world and $10,000 each in spending money. She announced it by spinning a globe in front of the team, and the video went viral.
The return: $5,000 invested in 2000, valued at $1.2 billion in 2021, representing a 240,000x return on her initial capital over 21 years.
What You Can Learn
Self-funding keeps everything. Sara Blakely owned 100% of Spanx for 21 years because she never needed anyone else’s money. Most online businesses do not need venture capital to start, and the women who start with their own money keep their entire upside if the business works.
Demonstrate the product, do not describe it. Blakely won the Neiman Marcus account by pulling a buyer into a bathroom and showing her the before and after on her own body. Every product that solves a visible problem should be sold by making that transformation impossible to ignore.
You do not need advertising if the product creates conversation. Sixteen years with zero ad spend sounds impossible, but Spanx grew entirely on word of mouth and earned media because women who wore it told other women about it. The best marketing budget is a product that people cannot stop talking about.
The first person to take you seriously might not be the decision-maker. A mill owner’s two daughters convinced their father to manufacture Spanx. Oprah’s stylist put the product on her before Sara ever spoke to Oprah. Sometimes the path to a yes runs through someone who believes in the idea before the person with the power does.
