Product Leadership

Stack of books with the front and back covers of 'Product Leadership' by Richard Banfield, Martin Eriksson, and Nate Walkingshaw. The front cover features a rocket illustration and the title in large red letters, with the publisher O'Reilly logo at the top.

My (ahem) best-seller

Good product management is critical to gaining and maintaining a competitive advantage. My co-authors Nate Walkingshaw, Richard Banfield, and I interviewed over 100 of the world’s top product leaders to uncover and share their insights into how to launch successful products and build great teams.

Published by O’Reilly in 2017 with a foreword from Ken Norton (then Product Partner at Google Ventures), our book has quickly become the de facto guide to product leadership, has been translated to six languages, and is a consistent best-seller in the category.
