Growth Marketing Manager: Paid Social

For too long, the bra industry was stuck in outdated ideas, forcing women to choose between feeling sexy or comfortable. So in 2013, Heidi Zak and Ra’el Cohen created Thirdlove–a third, better option designed to help women look and feel their best.

Prioritizing real-world fit over outdated standards, Thirdlove disrupted the industry by inventing half-cup sizes and the Fitting Room® quiz. The result was a more precise fit that offered comfort without sacrificing style. Today, Thirdlove remains an innovative design-led brand, handling everything from R&D to the supply chain in-house to get every detail just right.
