#764 – TikTok, AI, and a $3M Soap Brand

What does it take to turn a homemade product into a multimillion-dollar brand? In this episode, Bradley Sutton speaks with Joe McCutcheon, founder of Carolina Castile Soap, and Marc Messer from Advanced Bionutritionals. Together, they reveal how product differentiation, creator partnerships, AI-powered systems, and even old-school direct mail can produce remarkable results in today’s e-commerce world.

Joe began making soap for his cleaning company before testing it on eBay and eventually launching on Amazon. After years of reinvesting his profits and producing batches from his kitchen and garage, he grew Carolina Castile Soap from $1.8 million last year toward a projected $3 million this year. Joe explains how professional packaging, distinctive scents, Helium 10 research, and a community of TikTok creators helped the brand stand apart. Today, approximately 70% of its revenue comes from Amazon, while TikTok Shop has become both a profitable channel and a source of additional Amazon demand.

Marc shares a very different path to growth at Advanced Bionutritionals, a primarily direct-to-consumer company generating between $30 million and $50 million annually. He breaks down the company’s marketing-first product launch process, multichannel profitability analysis, and use of AI to create SOPs, forecast inventory, analyze real-time data, and generate dozens of advertising variations within minutes. He also explains why long-form direct mail still works for the right demographic and why brands need a proven sales message, sufficient cash flow, and patience before testing it.

Whether you are making your first product at home or managing tens of millions of dollars across multiple channels, the principles remain the same: understand your customers, create something worth remembering, and build systems that give your best people room to grow. Success rarely comes from following the crowd. It comes from remaining curious, acting on what you learn, and having the courage to build the brand your customers will never want to leave.
