Concentration can create shortterm profitability, but it rarely creates longterm stability
Every business leader understands the value of deep, trusted customer relationships. They fuel growth, strengthen reputation, and create the kind of partnership that seems lasting. But even the strongest relationships can’t eliminate a common risk: customer concentration. When too much of your revenue is tied to too few customers, or too few market segments, your company’s future becomes vulnerable in ways that are often invisible until it’s too late.
Research from McKinsey demonstrates the power of diversifying your company.
Companies with diversified revenue streams grow 2–3x faster and recover 50% more quickly during market disruptions.
I once worked with a company that had 80% of its revenue tied to a single national customer. Their performance metrics were better than all the other vendors in customer’s system. Their long-standing relationship was collaborative and built on trust. Yet none of that mattered when a new executive joined the customer and decided to diversify vendors. Overnight, the company lost 40% of its total revenue. Not because of poor performance. Not because of a failed relationship. Simply because the customer’s strategy changed. The impact was immediate and painful. Loyal employees paid the price for a risk the company never believed would materialize.
This isn’t an isolated story. In fact, companies with more than 30% of revenue tied to a single customer are considered “highrisk”. A 2024 PitchBook report noted that customer concentration is one of the top three reasons deals fall apart, even when the underlying business is strong.
Customer concentration isn’t the only threat. Industries and market segments experience volatility that can impact even the healthiest businesses. As just a few examples, commercial construction is down 8–12% in several regions, freight and logistics slot rates are down more than 20%, and consumer retail bankruptcies were recently up nearly 30%. When your revenue is overly weighted in one segment, your company becomes tied to the fate of that segment—regardless of how well you operate.
The truth is simple: concentration can create shortterm profitability, but it rarely creates longterm stability. Just like personal investing, being overly weighted behind a few key “positions” may feel smart when things are going well, but it exposes you to outsized risk when conditions shift. And conditions always shift.
If any part of this feels familiar, you should not push this off until sometime later. Expanding into new customers, new industries, or new market segments isn’t just a defensive strategy. It’s also a growth strategy. Pursuing new customers or market segments opens doors to new revenue streams that can accelerate your growth and success.
