Company case
iRobot
An installed base is not a moat until you build on it
iRobot invented the category and then watched it commoditise. Chapter 4 traces the slide from around 60% to 25% market share as Roborock, Ecovacs and Dreame turned faster, cheaper and increasingly better, using the same offshore manufacturing advantages iRobot had itself relied on. The $1.7 billion Amazon acquisition, signed in 2022, died in regulatory review in January 2024, and the company warned investors of substantial doubt about its viability. Its answer was eight new Roomba models priced against the Chinese competition: a battle on price, the one terrain where its installed base gives it no edge.
The book's stress test is iRobot Select, a subscription that bundled a premium robot, accessory replenishment, a protection plan and an upgrade every three years for a monthly fee. It did not hold. Tangibles works the numbers, arriving at an NPV of roughly $729 per subscriber once churn is counted from month thirteen, and argues the flaw was structural: the subscription was a financing wrapper around the device, not a new layer of value.
The forgone opportunity was the top layer of the book's Tangible Stack: a marketplace. iRobot had what most hardware companies spend years trying to earn, a large installed base, repeated household presence, maps of millions of homes, and permission to operate inside them. A third-party service network built on that presence is the moat the company never activated.
