David Bell
Show Notes

David Bell, former Wharton marketing professor and early investor in Warby Parker, explains why your zip code has a hidden influence on your spending habits. He introduces the 'preference minority' concept—the idea that local retailers stock for the average customer, leaving a minority underserved and ready to buy online. The conversation covers Warby Parker's origin story, how a failed meal-kit startup revealed demand patterns, and the transformation of hand sanitizer into a status symbol. Bell also discusses how AI is making market research accessible to any entrepreneur.
