Allison Ellsworth of Poppi: Speak From the Heart
Allison Ellsworth spent seven years on the road working in the oil and gas industry. It took a toll on her health. So she took her discontent to her own kitchen. She felt she was getting health benefits from drinking apple cider vinegar, but hated the taste. Could she concoct something fruity, low-sugar, and with prebiotics? She’s Allison Ellsworth, the founder and chief of brand at Poppi. You may have seen the bright-colored cans on grocery store shelves, or on Shark Tank, or on TikTok. But before Allison was a DTC alt-soda sensation, she tells host Christine Lagorio-Chafkin, she was driving across the United States knocking on doors.

Making Creative Space, With Lindsay McCormick of Bite
Lindsay McCormick started her business without really meaning to start a business. She just wanted to try to make a sustainable, healthy toothpaste, without the landfill-bound packaging, for herself and her friends. But then to pay expenses she started selling it–and it took off, with increasingly eco-conscious consumers. She was inspired in part by the nature she was surrounded by in Southern California–she was a snowboard instructor and a surfing instructor, too. Today, while running Bite, which stands for Because It’s The Earth, and sells personal care items that are compostable, refillable, and plastic-free, she still finds inspiration way out in the deep.
