Books by Arjun Sen
The work behind
ZenMango.
Lived in the business. Earned in the trenches. Shared through books.
For more than 30 years, Arjun Sen has worked inside businesses and alongside leaders, helping brands uncover what makes them one of one.
These books collect the ideas behind that work. Together, they trace a journey from creating a single memorable moment to earning a lifetime of customer returns.
They are not theories observed from the outside. They come from real brands, real decisions, real mistakes and real growth.
Published Books
Where the thinking began.
These books introduced ideas that continue to shape ZenMango today: relationships over transactions, experience over promotion and growth built from the inside.
Wow One More®
Secrets to Win Big® from 13 Restaurant Leaders
What does it take to turn one win into the next?
Through candid conversations with 13 restaurant leaders, Arjun Sen brings together practical lessons in leadership, culture, customer experience, brand building and growth.
Wow One More® is for anyone who has experienced success but knows there is another level ahead. It reveals how accomplished leaders keep learning, protect what makes their brands special and create the momentum to win again.
Customer Karma®
Why Stop at a One-Night Stand When You Can Have a Lifetime Relationship with Your Customers?
Customer loyalty is not a program. It is the return a business earns through its actions.
Using the honest analogy of dating and relationships, Arjun Sen exposes the blind spots that turn promising customer connections into one-time transactions.
Customer Karma® challenges leaders to stop focusing only on acquisition and begin earning the trust, care and consistency that create lasting customer relationships.
Good Customer Karma® is not what a company says. It is what the customer experiences.
Author Direct Releases
Not available where books are traditionally sold.
Books are printed. This work was aged.
Arjun's newest books follow a different path.
They are not released through bookstores, Amazon or traditional publishing channels. Each title is released directly by the author for leaders, owners and builders who are ready to put the ideas to work.
These books were not created to fill shelves. They were shaped over decades in restaurants, boardrooms, customer conversations and the moments when strategy either became real or fell apart.
Every copy is intentional. Every reader is connected directly to the work.
Thirty years in the making. Never on a shelf.
Glad You Came
Guest Leadership and the Feeling Business®. It Started in Restaurants.
Coming September 24, 2026
Every guest begins with a simple decision: Where should we go?
The real business begins after they arrive.
Glad You Came returns leadership to the restaurant floor, where a brand promise becomes a feeling through thousands of small actions.
Drawn from Arjun's experience as an operator, marketer and restaurant advisor, the book explores how leaders can create experiences that make guests feel seen, teams feel purposeful and people genuinely glad they came.
Because the best hospitality does more than complete today's visit. It earns the next one.
The Feeling Business®
People may choose with their minds. They return because of how you made them feel.
Coming October 2026
Most brands compete on what they do. The strongest brands are remembered for how they make people feel.
The Feeling Business® brings together the foundational thinking behind ZenMango. It shows leaders how to uncover the emotional truth already inside their brand, turn it into a one-of-one position and align the organization to deliver that feeling consistently.
When customers feel something distinctive, they choose. They return. They refer. They belong.
That is not simply marketing. That is purposeful brand growth.

The Return Business
Arjun Sen
The Return Business
The first visit creates a transaction. The return creates a business.
Coming October 2026
Growth is often measured by how many customers arrive. Enduring growth is built by how many freely choose to come back.
The Return Business introduces the customer's return as the most meaningful vote of confidence a brand can earn. It reveals where businesses quietly leak loyalty, why satisfied customers still leave and what makes a brand worth choosing again.
Through ideas including the Leaky Bucket® and the Return Vote™, Arjun challenges leaders to see retention differently.
Acquisition brings a customer through the door. Feeling gives them a reason to return.
