“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.” — Daniel Ek
