The Ten-Customer Business

A dangerous idea, born on Sand Hill Road to serve the unique mathematics of venture capital, has quietly infected the entire world of business. This is the story of the Total Addressable Market (TAM), a metric that demands infinite growth and has led countless otherwise viable companies, from Gumroad to Peloton, to the brink of ruin. Founders are taught that their only value lies in capturing a massive market, a delusion that has cost them their companies and their well-being.
"The Ten-Customer Business" chronicles the history of this destructive myth and reveals the powerful alternative. Through case studies of hyper-profitable outliers like the law firm Wachtell Lipton and independent consultant Tom Critchlow, the book dismantles the logic of scale. It demonstrates how deliberate constraint, profound specialization, and a focus on a tiny client list can generate extraordinary wealth and personal autonomy, far beyond what the "scale or die" mindset can offer.
This investigation uncovers the hidden physics of boutique success and provides a blueprint for building a business that serves its owner, not the other way around. Discover the radical, counterintuitive path to living well on a deliberately small client list.
