Regarding the Reprint of the Book
■ Background
This book was written with the intention of providing actionable insights for business leaders, executives, and digital transformation professionals responsible for improving the productivity of revenue organizations and driving revenue growth through value delivery to customers. We have received positive feedback from a diverse range of individuals, including engineers and HR professionals. The reprint is a reflection of the growing interest in the RevOps model, which is essential for sustainable growth in an uncertain era.
■ Comment from the Representative of Shoeisha Co., Ltd.
The book, which provides an in-depth explanation of the world's most advanced revenue operations (covering marketing, inside sales, sales, and customer success), has gained significant attention and, thanks to its success, has been immediately reprinted following its release. Many companies still face issues of siloed data and processes, with revenue data scattered across various departments. In the U.S., however, many companies are addressing these challenges by establishing specialized RevOps teams, leveraging technological expertise, analytical skills, and execution power to support their revenue organizations. According to Openprise's 2024 survey, over 67% of U.S. companies report having a dedicated RevOps department or role. This book not only covers the basics of RevOps but also provides practical steps for implementation and useful know-how for execution. It is a must-read for any company aiming to enhance productivity and achieve sustainable revenue growth.
■Feedback from Our Readers

- "As we begin to build our organization, I would love to distribute this book to our team as a textbook for creating a shared language."
- "In a time when traditional organizational models no longer suffice, I now have a clear understanding of the missions required for CRO and RevOps."

※1 About Marketing Operations (MOps)
Marketing Operations (MOps) refers to the function responsible for designing and maintaining strategies that integrate people, marketing technology, and marketing processes. Often described as the bridge between marketing and IT, MOps professionals possess expertise in marketing technology, analytics, and execution, working between the IT department and field marketing teams to implement marketing campaigns. Typically structured close to the CMO or management team, MOps is essential for driving organizational marketing operations in a systematic, rather than ad-hoc, manner. In Europe and the U.S., professionals with experience in field marketing or IT often transition into MOps roles as a career advancement path.
