What do these three things have in common: brushing your teeth, flossing, and Lenny Kravitz? They’re all key components in Twice, the oral hygiene brand that believes a good smile has the power to change lives. Our guest today is Cody Levine, who co-founded the company with his brother Julian and yes, Lenny Kravitz. The two brothers grew up in a household that prioritized proper oral hygiene, but that isn’t exactly surprising given that their father is a dentist. But they didn’t initially set out to continue down the same trail as their dad. Cody and Julian set out on their own different career paths in advertising and finance, respectively. On occasion, they would join their dad on dental missions to impoverished areas around the world. It was the impact that they had on those communities that led them to start Twice and make healthy smiles more accessible to everyone.
