Heidi Zak


Heidi Zak is the Co-Founder and CEO of ThirdLove, the 3rd largest online bra and underwear company in America. She is on a mission to get every single woman in a great-fitting, beautiful and comfortable bra that makes her feel confident. She believes inclusivity should be the norm, not the exception, and has led the charge, inventing half-cups and offering women more than 80 sizes. Zak left her job at Google with the dream of offering women a better option and marketing to them in a way that didn’t insult their intelligence or push impossible beauty standards. Seven years later, more than 17 million women of all shapes and sizes have used ThirdLove’s innovative Fit Finder™ to find a bra that truly fits her body. ThirdLove is proud to have donated over $30 million worth of bras to women in need.

Zak has been recognized as Fortune’s 40 Under 40, EY Entrepreneur of the Year, National Retail Federation’s Disruptors, Fast Company’s Most Creative People and Goldman Sachs’ 100 Most Intriguing Entrepreneurs. In addition to contributing a weekly column to Inc.com, Zak is committed to promoting and advancing more women in tech. She is an active angel investor in early-stage female-founded companies. She graduated from Duke University and holds an MBA from MIT Sloan. Prior to launching ThirdLove, Zak was at Google, Aeropostale, McKinsey and Bank of America. In her spare time you can find her working out, or chasing after her kids.
