The Growth Department

How Account Management and Customer Success Become the Revenue Engine
praise

“Everyone wants 10x growth, but most teams are stuck doing 2x work. Real
compounding happens when you raise the floor. This is the playbook.”

- Dr. Benjamin Hardy, bestselling author of
10x Is Easier Than 2x and The Science of Scaling

The Premise

The Growth Department makes the case for a different model
Most B2B companies invest heavily in acquiring new customers.

Then they underfund the teams responsible for keeping and growing them. Sales gets systems.

Marketing gets budgets. Post-sale gets told to “keep customers happy.”

Meanwhile, 70-80% of revenue comes from existing customers. Nearly all profit is earned after the first deal.

The Growth Department makes the case for a different model: one where Account Management and Customer Success operate as a growth function, not a service function.

Who this book is for

This book is for people who already know Post-Sale matters. And suspect it could matter a lot more.

Account Managers and Customer Success leaders who own revenue, not just relationships.

Founders and executives responsible for retention, expansion, and long-term growth.

CROs and CCOs rethinking where growth actually comes from.

If you’ve ever felt the distance between how post-sale is treated and how much it actually drives, this book was written for you.

Core Ideas

1. There’s no such thing as recurring revenue.
Revenue is re-earned every year. Every renewal is a decision. The companies that treat it otherwise are the ones surprised by churn.

2. Protection isn’t growth.
Most post-sale teams are designed to reduce risk. That’s not the same as creating value. The Growth Department is about building a function that does both.  Account Managers are running businesses.

3. The best ones think like owners.
They see their accounts as portfolios to grow, not relationships to maintain. That changes the conversations they’re invited into.

4. Capacity is a prerequisite for strategy.
You can’t lead customers if your calendar is consumed by internal noise. The book shows how top performers reclaim the time required to do the work that actually matters.

What's Inside

The book is organized around three questions
1. Why does this matter now?
The economics of B2B growth have shifted. Retention and expansion aren’t just important. They’re where the math actually works.

2. What does the work look like?
How to think about accounts as portfolios. How to spot expansion before the customer asks. Why most QBRs fail, and what replaces them.

3. How do you build a Growth Department?
What leadership needs to change. How to structure teams, incentives, and reporting so post-sale becomes a growth function, not a cost center.

Proof It Works

One Account Manager inherited a $50,000 account.

Instead of managing requests and waiting for renewals, she asked a different question: “Where do you want to be in five years?”That question changed everything.

Over time, the account grew to $10 million in annual revenue. Not through pressure. Through clarity, curiosity, and a different understanding of what Account Management could be.

Her story runs through the book.

“I spent my career proving what Account Management can be. I hit quota 17 years straight. But I had no playbook, no system, no language to explain what I was doing. This book is everything I figured out, and everything I wish someone had handed me when I started.”
