Episode Details

On today’s episode, we welcome Joey Zwillinger, Co-Founder and CEO of Biologica — a science-backed wellness brand redefining hormonal health for women at every life stage. Best known for co-founding Allbirds and leading the company through its IPO, Joey is now applying his category-creation expertise to a new frontier: women’s wellness. Built alongside his wife Elizabeth and inspired by her lived experience navigating decades of hormonal shifts, Biologica was created to address a major gap in the supplement industry — the lack of targeted, stage-specific support for women.
Joey’s path to launching Biologica reflects a career dedicated to purpose-driven innovation. After helping scale one of the most recognizable direct-to-consumer brands of the last decade, he turned his focus toward consumer health, bringing together clinical expertise, thoughtful design, and a mission to better support women’s biology. Formulated with OB/GYNs and naturopathic doctors, Biologica’s effervescent Essentials offer a pill-free, daily ritual designed to deliver energy, balance, and long-term vitality without the overwhelm of complicated routines. By blending science with accessibility, the brand is helping reimagine what modern supplementation can look and feel like.
In this episode, Joey shares what he learned building Allbirds and how those lessons translate — and sometimes don’t — in the health and wellness space. We discuss identifying white space in a crowded market, building a brand from real consumer pain points, and why treating women as one-size-fits-all is no longer acceptable. Joey also offers insights on leadership, scaling with intention, partnering with family, and the future of direct-to-consumer in consumer health. A thoughtful conversation for founders, innovators, and anyone interested in the evolving landscape of wellness.
