People. Process. Customers. Math.

Watching companies grow (or get stuck) for the past two decades has given me a unique view of what really drives business growth.

I’ve seen it across industries, but it’s clearest in MSPs and software companies. No matter the size or stage, the same four factors determine growth: people, process, customers and math.

People

The same people who got you here are unlikely to get you 2–3X further. That applies to operations, finance, sales and sometimes even the CEO.

We love our teams and want to stay loyal, but loyalty can be expensive. If you focus first on sales growth, you may be able to layer in more experienced leaders instead of replacing your current ones. But one way or another, something has to change or you’ll stay stuck.

Process

Processes have to evolve constantly. Mature leaders learn to solve symptoms with process, seeing every issue through a systems lens. Once you develop that view, you stop firefighting and start scaling.

Customers

A $2M MSP has a very different customer base than a $5M or $10M MSP. You can’t grow if your customer mix stays the same.

Review your base quarterly. Fix or replace poor-fit customers. Revisit your service offering and raise your minimum monthly spend for new clients. Growth demands evolution.

Math

Understand the key drivers in your business and make sure metrics cascade to every individual contributor. Most leaders track “symptom math” instead of “root-cause math.” Knowing the right numbers (and acting on them) creates clarity and accountability.

You might be thinking: “Gary just told me I need new customers and new employees to reach my goals.”

Well, yes. That’s basically what I’m saying. Most companies that double and double again end up with only a small percentage of their original people and customers.

That doesn’t mean everyone changes, but it does mean significant change. Across all the businesses I’ve built, only a few people have been with me for decades. More have changed than remained. I can’t think of a single exception.

So, ask yourself: Is the growth I want worth the change it requires, or is keeping my current team and customer base more important than scaling?

Either answer is fine but just be honest with yourself.

Because one thing is certain: You can’t have rapid growth and very little change at the same time. That’s not how growth works.
