Fortune’s annual 40 Under 40 ranks the most influential people in the business, and we’re incredibly proud to announce that ThirdLove’s own Heidi Zak was spotlighted in this year’s list. Standing at #38, our Co-founder and CEO was featured among an impressive roster of innovators and disruptors, including Facebook’s Mark Zuckerberg, Glossier’s Emily Weiss, and Bumble’s Whitney Wolfe Herd to name a few.

ThirdLove was born in 2013, and has since become one of the fastest growing businesses in the US. Together, Heidi and her Co-founder, CEO, and husband, David Spector, disrupted the lingerie industry and built a modern brand for women that focuses on fit, style, and comfort. Fortune recognized ThirdLove’s unique direct-to-consumer model, our signature half-cup sizes, and our data-driven Fit Finder quiz that helps women find their perfect fit.

Cheers to Heidi and the future of ThirdLove!
