SHOW SUMMARY In this episode, Jonathan Goldhill is joined by Casey O’Quinn, founder of Gravity Digital, a family-owned agency serving family-owned DTC brands for 25 years, about marketing as capital allocation that can drain family wealth and strain relationships when spent on vague retainers without measurable return. Casey contrasts traditional hourly/retainer agency models with Gravity Digital’s revenue-share approach, where the agency is paid only on growth above a baseline, aligning incentives and enabling investment in creative, websites, and testing.
