On this episode of On the Right Stack, host Jason Cohen sits down with Russell Kern, the serial entrepreneur who built one of Omnicom’s first true data-driven precision marketing agencies. Russell grew Kern from a startup into the firm that helped scale DirecTV, T-Mobile, and Sprint before Omnicom acquired it. The conversation moves from precision marketing to leadership, covering why customer understanding is an organizational problem and not a data problem, how to treat AI as a power tool without surrendering human judgment, and why humility and vulnerability are lasting leadership strengths.
