The original product served dental practices. It was a small market—maybe ten thousand potential customers nationally. The investors wanted bigger.
"What about all healthcare practices? Doctors, chiropractors, physical therapists?" The addressable market grew tenfold on paper. The pitch deck improved. The round closed.
The product expanded. Features for different practice types. Marketing that spoke to everyone. A sales team calling across healthcare.
Revenue dropped. The dental practices that had loved the specialized solution churned when the product became generic. The broader healthcare market didn't convert—they had options built specifically for their needs. The company was stuck between markets, succeeding in neither.
The small market had been the right size. They just hadn't realized it.
The Expansion Instinct
Founders naturally gravitate toward larger markets. More customers mean more opportunity. Bigger TAM impresses investors. Expansion feels like progress.
This instinct is often wrong, especially before product-market fit.
Large markets have more competition. They require more resources to reach. They're harder to dominate. The advantages of size come with disadvantages that founders underestimate.
Small markets have the opposite properties. Less competition. Easier to reach. Possible to dominate. The limitations come with advantages that founders overlook.
Why Niches Work
Several dynamics make niche focus powerful.
Deep understanding becomes possible. When you serve one narrow segment, you can truly understand them. Their specific problems. Their specific workflows. Their specific language. This depth translates into better products. Word of mouth travels fast. People in niches know each other. Dental practices talk to dental practices. When your product works for one, others hear about it. The network effects within niches are stronger than across broad markets. Competition is lighter. Big players ignore small markets. The effort to customize for a niche doesn't justify the revenue opportunity for large companies. This creates space for specialists to thrive. Pricing power increases. Generic solutions compete on price. Specialized solutions compete on fit. When your product is built specifically for someone's situation, they'll pay more than for something sort-of-applicable. Positioning is clearer. "Project management for construction companies" is instantly understandable. "Project management" competes with a thousand alternatives. Clear positioning attracts the right customers and repels the wrong ones. Sales cycles shorten. Customers recognize themselves in your marketing. They see case studies from peers. The evaluation process shrinks because the fit is obvious.The Fear of Limits
Niche focus triggers founder anxiety. What about all the customers we're excluding? What if the market is too small? Won't we cap our growth?
These fears are usually overblown.
Most niches are bigger than they appear. "Dental practices" sounds small until you count them. "Solo attorneys" sounds tiny until you see the numbers. Actual niche sizes often surprise founders who dismiss them. Dominating a niche is valuable. 80% market share in a small market often beats 2% of a large market. The revenue can be similar, but the competitive position is far stronger. Niches expand. Win dental, then win other healthcare verticals. Win solo attorneys, then win small law firms. Success in one niche funds expansion to adjacent niches—from a position of strength rather than desperation. Total addressable market isn't destiny. Investors care about TAM, but TAM doesn't determine company outcomes. Many huge markets have no successful companies. Many small markets support excellent businesses.Finding Your Niche
If you're currently serving a broad market, how do you identify the right niche?
Look at your best customers. Which customers love you most? Use you most? Churn least? Pay most? They often share characteristics. That cluster is your niche. Examine where you win. In competitive situations, when do you win? The contexts where you beat alternatives reveal where your product fits best. Consider founder expertise. Where do you have unusual insight or credibility? Founder-market fit matters. The niche where you have natural advantages is often the right one. Find the specific pain. Where is the problem most acute? The niche with the most intense need will respond most strongly to a solution. Talk to users. Customer discovery reveals segments. When you hear the same phrases from multiple people in the same industry or role, you've found a cluster worth focusing on.The Niche Commitment
Focusing on a niche requires commitment. Half-measures don't work.
Marketing speaks directly to them. Not "businesses" but "independent restaurants." Not "teams" but "remote design agencies." The specificity attracts. Product reflects their needs. Features they actually use. Integrations with tools they actually use. Workflows that match how they actually work. Sales understands their world. Representatives who can speak the language. Case studies from similar companies. Demo environments that feel familiar. Support knows their context. Help that reflects understanding. Documentation that addresses their specific situations. The feeling that you get them.Going halfway—niche marketing but generic product, or niche product but broad marketing—undermines the approach. The power of niche comes from full commitment.
When Niche Fails
Not every niche works. Some are too small. Some are declining. Some have prohibitive characteristics.
Truly insufficient market. If the math doesn't work—even with high market share and premium pricing—the niche is too small. This is rare but real. Declining niche. Markets in structural decline aren't saved by focus. The niche must have a future. Unreachable niche. Some segments are impossible to target efficiently. If you can't identify or reach them, focus provides no advantage. Commoditized niche. If the niche is well-served by competitors already, focus doesn't help. The advantage comes from being the specialized option, not one of many.Due diligence on niche characteristics matters. Not every narrow market is worth pursuing.
The Expansion Path
Niche focus isn't permanent imprisonment. It's a starting point.
The pattern: dominate one niche, then expand to adjacent niches, then perhaps to broader markets. Each step builds on the previous success.
Basecamp started serving design agencies, then expanded to creative teams more broadly, then to teams generally. Each step from a position of strength. Salesforce started with small sales teams, then moved upmarket to enterprise, then across functions. The expansion followed dominance. Shopify started with small e-commerce, then grew into larger merchants, then into point-of-sale and payments. Each stage funded by the previous.The niche isn't the ceiling. It's the foundation. Build on it rather than around it.
The Counterintuitive Truth
The niche paradox: smaller focus leads to larger success.
This runs counter to instinct. It feels like leaving money on the table. It seems less ambitious than serving everyone.
But the companies that win usually started narrow and expanded. The ones that started broad often stayed stuck—competing everywhere, dominating nowhere.
The market rewards depth before breadth. Prove you can own a niche before trying to win the world. The path to big runs through small.
Moving Forward
If you're spread across too many markets, consider narrowing. Which segment loves you most? Which would miss you most if you disappeared? Where do you have the strongest competitive position?
That's your niche. Commit to it. Build for it specifically. Win it completely.
The fear of being too small usually isn't realized. The reality of being too diffuse usually is.
