Michael and Rishon would like to thank:
The 10x Management, 10x Ascend, and Brick Wall Management teams (both current and past) for always striving to be 10x and enduring our endless book talk during this process: Griffith Adams, Michelle Humphries, Ryland Kenyon, Isaiah Machiz, Ben Miller, Michael Warner, Serena Yannello, and Sam Zeisler. And we’d especially like to thank all our 10x and Brick Wall clients for being the heart and soul of our ideas and execution. It’s through our work with all of you that the concepts for this book were formulated. Thank you to Daniel Weizmann (Danny to us) for so many things, but most important, for tirelessly helping us put words and order to the chaos of the ideas in this book. We’d like to thank Altay Guvench for introducing us to the concept of 10x, for being our first coder client, and for co-founding 10x Management with us.
Michael, Rishon, and Daniel would like to thank:
The 10x-level team that made this book possible, starting with Lucinda Halpern and everyone at Lucinda Literary for agenting the agents with skill and passion, for helping us develop these ideas with care and finesse, and for providing us with true Inner and Future Vision. Tim Burgard for bringing us into HarperCollins Leadership and editing this work with patience and professionalism. Jeff James for believing in us and welcoming us into the HarperCollins Leadership family. Sicily Axton for helping to execute a wonderful marketing plan and introducing this book to the world. Mark Fortier and the team at Fortier Public Relations for your dedication and hard work. Christina Clifford for being the first person to encourage us to write and publish this book. Her early belief truly made a difference, and she was instrumental in introducing us to our literary agent. Margo Schupf who was also an early advocate and who gave us the confidence and guidance to get started. David Halpern for being wise enough to introduce us to Lucinda, and Geoff Shandler for his wonderful advice and generosity of time and spirit.

Rishon would like to thank:
A special thank you to my wife, Dr. Isabel Blumberg, whose early belief in this book was a genuine motivator 
and to my amazing boys, Alec and Luke Blumberg, who are true inspirations to me and are budding 10xers themselves—work hard, believe in yourself, and you can achieve whatever you set your mind to. I would like to give extra special thanks to my mother, Aviva Blumberg, who read every chapter of this book in real time and provided insightful feedback, and unyielding encouragement. Thank you to Nina and Larry Epstein, my wonderful and loving in-laws, for always supporting me. Thank you to Amy and Will Gadsden and Brian and Lauren Epstein for being the best brothers- and sisters-in-law anyone could hope for. And thank you to my beautiful and talented nieces, Lindsay, Merrill, Lucy, Chelsea, and Edie, who make me laugh and keep me on my toes. I would like to thank Michael for being my partner in crime since third grade, and Daniel, whom I’ve known all my life. This book would never have happened if not for the tireless efforts of both of you.
Daniel would like to thank:
Clover Chadwick, Max Weizmann, Rama Weizmann, and Aviva Blumberg for their enduring love, patience, and support. He’d also like to thank Michael and Rishon for introducing him to a complex, captivating new world and a wealth of truly useful ideas.
