From Library Books to Leading E-Commerce Brands: Sarah’s Founder Journey

In this episode of Founders Future, with host Milan Kohut, we sit down with Sarah Levinger, consumer behavior strategist and founder of Tether Insights, to explore her unconventional journey from generalist marketer to one of the most respected voices in psychology-driven advertising. Sarah shares how a decade spent studying neuromarketing, brain processes, and emotional cues—much of it self-taught from library books—laid the foundation for her signature approach to understanding why people buy. From early days building WordPress sites and running lead-gen for hotels to mastering e-commerce advertising during the COVID boom, Sarah explains how slowly refining her psychological frameworks eventually sparked the creation of Tether, a system designed to decode emotional insights and transform them into high-performing, strategic ads.Sarah also reveals how she built her business almost entirely from organic content—posting four times a day, five days a week, for five years—and why human psychology, not tactics, is what truly drives marketing success. Inside the episode, she breaks down the evolution of her model from consulting to fractional strategy to SaaS, the challenges of being a solo founder with young kids, and her commitment to sustainable growth over arbitrary revenue milestones. She reflects on hiring, delegation, AI’s limitations, and the future she envisions for Tether: a scalable tool enhanced by human expertise, a growing team, and a balanced life rooted in intention rather than hustle. It’s a candid, insightful conversation about entrepreneurship, identity, and building a business that actually fits the founder behind it. Connect with Sarah Levinger:🔗 X(Twitter):  https://x.com/SarahLevinger
