When Sarah Moret launched Curie in 2018, she was a venture capitalist by day and a budding entrepreneur by night, shipping deodorants from her living room floor. Moret’s journey from side hustle to an eight-figure clean beauty brand has been one of persistence, strategic growth, and an incredibly calculated appearance on Shark Tank. Her pitch ultimately secured a deal with Mark Cuban and Barbara Corcoran, but what came after was even more impressive—a tenfold increase in business and a brand that is now a rising force in the personal care market.The Birth of Curie: A Personal Problem Turned Business OpportunityMoret’s path to founding Curie started out of necessity. A former marathon runner, she struggled to find an aluminum-free deodorant that could keep up with her active lifestyle. “I was always super into health and wellness, but when I started looking at the ingredients in my personal care products, I was shocked,” Moret tells BeautyMatter. “A quick Google search showed me how many of these everyday ingredients were petroleum-derived or endocrine disruptors,” she recalls. Deodorant was the toughest switch—nothing on the market lasted long enough to meet her needs.This grew a determination to find a solution and caused her to collaborate with expert formulators in the deodorant industry. “We worked for a year to develop our first formula, and since then, we’ve iterated four more times based on customer feedback to make it even better.” With $12,000 of her own savings, she launched Curie, initially handling every aspect of the business herself, from formulation to fulfillment.
