7 Powers: The Foundations of Business Strategy

“Hamilton Helmer is the best kind of big thinker – he offers great insights that you can turn into real world action. At Spotify the 7 Powers are widely used as we discuss new initiatives. His distillation of the key types of strategic power, how to find them, how to leverage them, and how to maintain them is a fantastic toolset for companies at every stage.”

Official jacket endorsement from Ek. He explicitly notes the 7 Powers framework is used inside Spotify when evaluating new initiatives.

“The forces of competition are just incredibly strong. Everyone is trying to eat your lunch, and if you don't read 7 Powers you're going to die a lot sooner.”

Endorsement on the book's official site. Hastings also wrote the book's foreword after Helmer taught the framework at Netflix.

Recommended for entrepreneurs on his reading list.

“Correctly places enormous value on execution and on culture”
