This episode breaks down one of the most legendary marketing case studies of the digital age. We dissect how Dollar Shave Club’s founder, Michael Dubin, used a single $4,500 homemade video to take on the razor monopoly, Gillette, and build a billion-dollar brand.

We explore the brilliant strategy behind the ad—how it leveraged humor, authenticity, and a deep understanding of customer frustration to go viral. You'll learn the specific tactics, the mind-blowing ROI (a 37-cent customer acquisition cost!), and the long-term impact that forced an entire industry to change. This isn't just a story; it's a masterclass in how bold creativity can crush massive budgets, with actionable lessons for any startup, marketer, or entrepreneur today.
