In this episode of Beyond The Deal, host Jill Yahnite sits down with Charlie Skinner, founder of Infinite Vision, a medical and biotech product development company specializing in optics and illumination engineering. Charlie also shares insights from his newer venture, Defense Audio Systems, a company developing technology designed to prevent crime and de-escalate dangerous situations. Drawing on decades of leadership experience across sales, engineering, and operations, Charlie challenges the traditional “hunter vs farmer” sales model. Instead, he argues that the best sales professionals remain deeply involved after the deal is closed — protecting relationships, managing expectations, and helping clients navigate complex projects.Charlie and Jill dive into the real dynamics of account management, including how salespeople can drive deeper account penetration, prevent scope creep disasters, and build long-term client partnerships that generate sustained growth.Guest Introduction:Charlie Skinner is the founder of Infinite Vision, a product development company focused on optical and illumination engineering solutions for medical and biotech applications.
