After giving up diet soda, Kara Goldin started adding fresh fruit to her drinking water to make it more fun. This inspired her to create Hint water, a line of unsweetened flavored water beverages that are now available in over 30,000 stores nationwide. Kara shares how sales have almost doubled as Hint invested in e-commerce during the pandemic, and offers her advice for entrepreneurs trying to break into saturated market spaces like the beverage industry. These conversations are excerpts from our How I Built Resilience series, where Guy talks online with founders and entrepreneurs about how they're navigating turbulent times.
