With so many shapes, sizes, and needs, the process of creating a flawless bra bubbled up a number of challenges, one of which was moving beyond the brick and mortar experience and developing better bra sizing and fit without ever meeting the woman in person.
ThirdLove Co-Founders and Co-CEO's, Heidi Zak and David Spector have been recognized by Goldman Sachs GS, +1.00% as two of the 100 Most Intriguing Entrepreneurs of 2018” who were recently honored at the Builders + Innovators Summit held in Santa Barbara, California.



The company has come a long way from its original data collection system — asking women, via a Craigslist ad, to come to its San Francisco headquarters wearing their best bra and take a photo of their breasts with an app that could calculate their bust size.
Ahead of the annual VS Fashion Show, model Robyn Lawley started a petition encouraging a boycott of the show due to its lack of size diversity, according to Teen Vogue ; she partnered with ThirdLove, who donated a bra to the Support the Girls organization for every Instagram post hashtagged #weareallangels.

Heidi Zak previously held a position in Google, and underpinned by this experience in the tech sector, and fuelled by her passion for retail and finding a bra that was a perfect fit—her research revealed that 80 percent of women wear bras that do not fit them correctly—and supported by the financial experience of her co-founder husband David Spector, ThirdLove was born in 2013.
One that includes adjustable lighting, digital measuring systems, three different types of dressing rooms and 78 bra sizes to choose from. Thirdlove innovated a fuller range that acknowledged the variety of women's bodies, including half-cup sizes that allowed for an even greater level of precise measurement.

Passionate about making great-fitting, comfortable and beautiful bras for all women. Spector said the company uses every digital channel they can to reach their customers, as well as some more traditional ad tactics like direct mail, TV, ThirdLove radio and billboards. The couple told the employees, many clad in their work uniform” — a grey t-shirt printed with ThirdLove — that the tremendous growth was because of their great service to customers of the online-only business.
