In this season‑3 finale of The Room podcast, hosts Madison McIlwain (DefyVC) and Claudia Laurie (Pryve) interview Heidi Zak, co‑founder and CEO of ThirdLove. The conversation traces Heidi’s early career in investment banking, consulting, and retail, her pivot to entrepreneurship after exposure to Silicon Valley’s startup culture, and the personal aha moment that revealed a massive gap in the bra market. Heidi explains how ThirdLove achieved product‑market fit through innovative fit technology, including half‑cup sizing and a data‑driven sizing app, and how the company raised over $70 million, detailing the seed round (Felicis) and the importance of a lead investor (NEA). She discusses the early operational challenges of hiring, manufacturing (on‑demand production failures, factory shifts), and the launch of a “Try Before You Buy” program that de‑risked online bra purchases. The interview covers distribution strategy (100 % D2C, limited wholesale, Bloomingdale’s partnership), the new model‑search initiative to boost diversity, and Heidi’s view on emerging e‑commerce trends such as personalized one‑to‑one communication, video chat, and live‑selling. Finally, Heidi shares personal productivity habits (sleep, exercise), mentorship influences, and advice on prioritizing health and time for founders. The episode blends storytelling with tactical advice for founders, investors, and operators in both software and non‑software D2C businesses.
