Margins: How the world's biggest companies make money
By Abhay Singh & Andreas Haselsteiner • Published 2025
With beautiful Sankey diagrams, Margins reveals how money flows through the world's biggest companies.
The past few years have been turbulent for business. The pandemic changed demand overnight. Artificial intelligence then created new winners and losers. Some industries shrank under pressure, others thrived like never before.
Margins takes you inside this transformation. You see revenues, costs, and the strategies that drive profit at companies like NVIDIA, Tesla, and Amazon.
The book also shows why software and logistics firms work in very different ways. One runs on code, the other on trucks and warehouses. And these differences appear clearly in their margins.
Whether you are a CFO, business leader, or simply curious, Margins gives a clear view of how the biggest companies make money.
