The GTM Podcast

Lou Shipley (three-time CEO, Harvard Business School professor, and author of Unlikely Entrepreneurs) joins GTMnow to break down why most founders struggle to turn good ideas into great companies. Lou has led companies through acquisitions, teaches sales and go-to-market at Harvard, and has spent decades studying what actually separates companies that scale from those that stall. In this conversation, we unpack why understanding customer pain and learning how to sell are still the two most important founder skills, especially as product moats decline and go-to-market becomes the real differentiator. In this episode, we discuss: - Why understanding customer pain matters more than having a great idea - Why early selling should optimize for learning, not revenue - Why founders can’t outsource sales too early - How distribution becomes a competitive advantage at scale - What makes “unlikely entrepreneurs” outperform expectations - Why small, high-quality teams beat large organizations - Why churn is a symptom, not the root problem - How product-market fit quietly changes as companies grow - Why founders must evolve from heroic sellers to system builders - How culture becomes a real go-to-market asset Lou also shares lessons from teaching sales at Harvard, profiling 13 unlikely entrepreneurs, and working with founders who realized too late that they were building the wrong company for the wrong customer. If you’re a founder, operator, or investor trying to avoid costly early mistakes and build a company that actually scales, this episode will give you a clearer mental model for what matters most.
