It’s 8AM. Do You Know Who Your Best Customer Is?

Churn is loud and your best customers are quiet, so the data reaching leadership skews toward the customers who are leaving. How to identify your most valuable customers, and why companies end up optimizing for the wrong ones.

Not your best segment. Not your highest-volume cohort. The actual person, or company in B2B, that spends the most with you. Their name. What they buy. How long they've been with you.

Now the harder question: Do you think that customer feels they are getting a special, differentiated experience from you?

One of the reasons I launched Bentley Strategy is that I kept seeing the same patterns inside marketing organizations. This is one of them.

Don't say it's a data problem

Most companies today are drowning in data and dashboards. The problem isn't access to information. It's that the information flowing up to leadership tends to cluster around a particular kind of customer: the one who's leaving.

Churn is loud. Your best customers are quiet. They just keep spending.

The data behind this is well-established. Across most industries, the top 20% of customers generate roughly 80% of revenue, a pattern so consistent it has a name: the Pareto Principle. In practice, the concentration is often sharper. Smile.io's analysis of over 100,000 ecommerce merchants found that just 8% of customers generate 41% of revenue, and the top 5% generate 35%. Whatever the exact ratio in your business, the implication is the same: a small group of customers is quietly holding up a disproportionate share of your results. And because they rarely complain or fill out surveys and reviews, they are under-represented in most Voice of Customer data.

Here's a real-world situation I've been in multiple times: I ask for a customer spend distribution, covering the top 20%, top 10%, top 1%, and top individual. The team pulls the numbers. The top 10% of customers represents more than 50% of sales. The top 1% represents roughly 20%. I ask them to keep going. I want a name. We find one: a customer spending millions per year with the company. We look at the outreach data. They're getting the same email cadence as everyone else. Same promotional sequence. Same sales contact frequency. Nothing differentiated. I take this to the Chief Sales Officer and ask:

"I'm not a salesperson, but why aren't we taking this person out to a steak dinner every quarter?"

That's probably the least we should be doing to retain this customer.

The good news: providing your best customers with a better experience doesn't require a data transformation, a new platform, or a six-month roadmap. Most marketing leaders can get meaningful answers in a week or less. Here's where to start.

A playbook: what to do this week

1. Get basic information on your best customers. Ask your analytics or customer intelligence team for a simple spend distribution: top 20%, top 10%, top 1%, and top individual customer by revenue in the last 12 months (extra credit: get margin as well). If this takes more than two days to produce, that's a signal you may not have the right tools, process, people, and/or prioritization in your Customer Intelligence team. Make sure to note that down as something to dig into later. It's solvable.
2. Make it personal. Get a real name, or a company name, in B2B. Who is your #1 customer? What do they buy? How frequently do they buy? How long have they been with you?
3. Pull the outreach history. How recently were they contacted? By whom? Through what channel? Was it a personalized conversation or an automated email blast?
4. Assess your customer focus. Roughly how much organizational energy (marketing budget, sales time, and leadership attention) goes toward winning back churning customers versus investing in your best ones? There's usually a significant imbalance.
5. Take one action to differentiate best customer experience. This is where strategy comes in, and the most important thing to remember is that differentiation doesn't always mean adding more. Does your best customer really need another promotional email? Another outbound sales call? Sometimes the most powerful thing you can do is remove the noise: swap the daily promo message for a genuine "thank you for your business," or simply leave them alone and let the relationship breathe. Your best customers don't always need to be sold to. They almost certainly want to feel recognized.

How it may play out

If you already have a formal VIP or top-customer program with dedicated attention, great. You're ahead of most. Use this as a prompt to pressure-test whether it's actually working.

If there's a gap, you now have the beginning of a business case. It might be a VIP account team. It might be a concierge-level service tier. It might be a supply chain investment pitched to Operations using best customer satisfaction or retention data. It might just be an in-person steak dinner from the sales rep.

One more thing worth noting: as you start digging into your best customer data, you'll almost certainly find insights that go well beyond what Marketing can fix on its own. A delivery problem. A service gap. A pricing issue. The temptation is to stick to what you can control and leave the rest for another department leader to discover and solve on their own. Owning and solving the customer issue you've discovered is the difference between being customer-centric and giving it lip service, and trust me, customers will know the difference and find somewhere else to do business. I'll get into that in my next article.

Start with the customer. Strategy follows.

Everything above starts with one question: who are your best customers, and what percent of your sales and profit do they represent? Trust me, once you know this information, it will come up in so many meetings you might just get sick of it, but it's a statistic that every leader, and every marketer, should know.

Customer intelligence isn't just a marketing input. It's what good strategy is built on, across the entire organization. When leadership teams can answer basic questions about their best customers without hesitation, every decision gets sharper: where to invest, what to fix, who to prioritize, and why. And the good news? Decisions based on customer understanding and empathy are a lot easier than those based on politics and competing pro forma assumptions.

If you're not sure where your team stands, it's worth finding out this week.

To be the customer's voice in every room. That's the CMO's job. Start with knowing whose voice you're carrying.
