The most common growth mistake I see isn't a bad strategy, weak marketing, or even a poor product. It's trying to grow before developing a clear understanding of who the customer actually is.
Most founders I meet have no shortage of ideas. They're testing new channels, experimenting with content, improving products, exploring partnerships, and thinking constantly about growth. That willingness to move quickly is often one of the reasons their businesses exist in the first place. The challenge is that speed can sometimes hide a more fundamental problem. When growth feels difficult, the natural instinct is often to increase activity. More campaigns, more content, more channels, more advertising. Sometimes those efforts create results. More often they amplify existing problems, because the underlying issue was never a lack of activity in the first place.
The biggest growth mistake isn't moving too slowly. It's moving quickly in the wrong direction.
Why This Happens
Founders are naturally close to their products. They've spent months or years thinking about the problem they're solving, speaking to customers, collecting feedback, and refining their offer. Over time, however, those insights can slowly turn into assumptions. As businesses grow, it's easy to begin making decisions based on what we believe customers want rather than continuously validating whether those beliefs are still true. The result is rarely one dramatic mistake. Instead, it's a series of small decisions made over time based on assumptions rather than evidence. Individually those decisions seem reasonable, but together they can slowly pull a business away from the customers it's trying to serve.
Customer understanding is often treated as the starting point of a business. In reality, it should be an ongoing practice.
The Questions That Get Skipped
When I look at brands that are struggling with growth, there are usually a handful of questions that haven't been explored deeply enough. Not because nobody cares about them, but because they seem obvious and therefore don't get revisited. Questions like: Who is actually buying from us today? What problem are they trying to solve? Why did they choose us over alternatives? What nearly stopped them from buying? What makes us different in their eyes? What language do they use to describe their problem? These aren't complicated questions. The challenge is that they can't be answered from analytics alone. They require conversations, curiosity, and a willingness to challenge assumptions.
The Cost of Skipping This Work
The consequences don't always show up immediately. At first, things might appear to be working. Customers are arriving, sales are happening, and growth feels possible. Over time, however, the cracks begin to appear. Marketing campaigns become less effective, conversion rates plateau, and different teams develop different ideas about who the customer actually is. Customer acquisition becomes more expensive and new initiatives produce inconsistent results. What initially looks like a marketing problem often turns out to be a customer understanding problem.
- Launching a new advertising channel
- Redesigning the website
- Switching content strategies
- Bringing in external agencies or consultants
- Adding more marketing tools
These investments can absolutely help. But if the underlying understanding of the customer is weak, the same challenges tend to reappear in different forms.
Where I Usually Start
When a founder tells me they're frustrated with growth, the first thing I look at isn't their advertising account, analytics dashboard, or conversion funnel. I want to understand how well they know their customers. Who is buying from you today? Why do those customers choose you? What alternatives are they comparing you against? What objections do they typically have? When was the last time you spoke to a customer? Can you support your assumptions with evidence? The answers to these questions often reveal more than any marketing dashboard. In many cases, they're the difference between a business that's guessing and a business that's making informed decisions.
Growth problems often look like marketing problems. Many are actually customer understanding problems.
A Simple Test
Imagine someone joins your business tomorrow. Without looking at analytics, reports, or dashboards, could your team confidently explain who your ideal customer is, why they buy from you, what alternatives they compare you against, and what typically motivates them to take action? If the answers are vague, inconsistent, or based mostly on assumptions, that's usually where I'd focus first. Clarity in these areas influences everything else. Your messaging becomes stronger, your positioning becomes clearer, your marketing becomes more effective, and your product decisions become more focused.
Growth gets easier when you're no longer guessing who you're trying to serve. The founders who grow most effectively aren't always the ones doing the most. They're often the ones with the clearest understanding of who they're building for, what problem they're solving, and why customers choose them over the alternatives. A clear picture of your customer is usually worth more than your next campaign.
