Why Your SaaS Has Zero Users (It's Not Your Product)

I see this all the time. Someone builds a SaaS product, a functional and sometimes even well-designed one, and then wonders why nobody signs up. They post about it on reddit. They ask for feedback. They tweak the landing page. They do SEO. They add features. Still nothing.

And I think a lot of the time, the answer is sitting in a blind spot they never think to check: they don’t actually understand the problem they’re trying to solve.

Not really. They understand it on the surface. They can describe it in a sentence. They’ve probably read a few blog posts about it. Maybe they talked to a couple people who have the problem. But they’ve never lived it. They’ve never been the person sitting in front of that broken workflow at 11 PM on a Tuesday, knowing exactly which part hurts and why the existing options don’t fix it.

That gap between understanding a problem intellectually and understanding it from the inside is the thing that separates products people actually use from products that just exist. I call it the EX factor. Domain experience as the ingredient you can’t substitute.

Why Isn’t My App Growing? Check Your Assumptions.

If you’re someone who loves to build things, this is especially dangerous territory. Because building is fun. Designing a system, writing clean code, watching something take shape. That’s satisfying work. And it can absolutely carry you through months of effort on something that nobody needs.

I’ve watched talented builders get so deep into the construction that they never step back and ask a pretty basic question: do I actually know what I’m building this for? Not in the abstract. Not “small businesses need better invoicing.” Do I know specifically what’s broken, what’s been tried, why it didn’t work, and what would actually make someone switch from whatever they’re doing now?

That level of understanding doesn’t come from research. It comes from experience. Years of it, usually.

The questions you’re not asking

It’s easy to validate that a problem exists. Anyone can find a subreddit full of people complaining about something. The hard part is understanding the texture of the problem. The workarounds people have built. The things they’ve tried and abandoned. The specific friction points they’d actually pay to eliminate versus the ones they’ve learned to tolerate.

If you can’t describe those nuances in detail, you don’t understand the problem well enough to solve it. And your product, no matter how well-built, is going to feel slightly off to the people who live with it every day.

I Built a Product but Nobody Wants to Pay for It

When a product launches to silence, the instinct is to blame the product. The UI isn’t polished enough. The feature set is too small. The pricing is wrong. The marketing wasn’t aggressive enough.

Sometimes those things are true. But more often, the product just doesn’t resonate. It solves a version of the problem that doesn’t match how real people actually experience it. You’ve built a solution for the problem as you imagine it, not the problem as it actually is.

I wrote about this from a different angle in The Question Nobody Asks: Why You?. Your personal connection to the problem is one of the most underrated factors in whether your thing succeeds. Domain experience is a huge part of that answer. It’s what gives you the instinct for which features matter and which are noise. It’s what tells you how people talk about the problem, where they go looking for solutions, and what they’ve already tried.

Without that, you’re guessing. And guessing at scale, building an entire product based on guesses, is expensive.

Free users but no conversions

This is the variant that really stings. People sign up, they poke around, and they leave. Or they use the free tier forever and never upgrade. The temptation is to blame the paywall placement or the pricing page copy. But often the real issue is that your product solves the problem just enough to be interesting and not enough to be essential.

That’s a domain knowledge gap. Someone who’s lived inside the problem knows the difference between “nice to have” and “I need this yesterday.” If your paid features aren’t landing, it might be because you don’t know which parts of the problem are actually worth paying to solve.

When Lack of Experience Doesn’t Matter

Some people with zero domain experience build wildly successful products. It happens. But look closely at when it happens, and there’s almost always a pattern: the field is new.

When an industry or technology is just emerging, when the rules haven’t been written yet and there isn’t real competition, domain experience matters less because nobody has it. Early social media, early ecommerce, early AI tooling. These were spaces where a smart builder with good instincts could stumble into something because the entire landscape was being defined in real time. And crucially, there were no existing solutions. Nobody had to be convinced to switch. There were no habits to break, no data to migrate, no workflows to relearn. People were adopting something from nothing, which is a completely different motion than replacing something they already use.

But that’s a specific and temporary condition. The moment a market matures even slightly, the people who’ve lived inside the problem start to dominate. They build better products because they understand the nuances. They market better because they speak the language. They retain users better because they anticipate needs that outsiders don’t even know exist.

The switching cost blind spot

This is another place where lack of domain experience kills you. In a mature market, you’re not just asking someone to choose your product. You’re asking them to stop doing what they’ve been doing. To leave behind the tool they’ve already configured, the workflows they’ve built around it, the integrations they’ve wired up, the muscle memory they’ve developed. That’s a massive ask, and most builders dramatically underestimate it.

People without domain experience tend to skip this step entirely. They look at the competition, see obvious flaws, and think “I can build something better.” Maybe they can. But they don’t understand why the market leader is the market leader. They don’t understand the dynamics. Sometimes a product dominates not because it’s the best, but because the cost of leaving it is higher than the pain of staying. If you don’t understand that, you’ll build a product that’s technically superior and still wonder why nobody switches.

This is especially true in B2B, which is where a lot of money-chasers end up because the ticket sizes are bigger and corporations seem to have bottomless budgets. It feels like a pot of gold you can just walk up to and take a scoop out of. But corporations have cultures. They have traditions, fiefdoms, training programs, pet projects, internal politics. They have a deep inertia around anything that seems to be working, no matter how clunky it looks from the outside.

So if you’re sitting on the outside thinking “I’m going to build a better Salesforce,” you’re probably revealing how little you understand about why Salesforce wins. Someone with actual domain experience, someone who’s lived inside that corporate Salesforce culture for years, would probably build something very different. They’d probably build something that makes Salesforce better, not something that replaces it. They’d work within the constraints as they actually exist, not as they appear from the outside.

That’s the difference between domain experience and a superficial read of the market. One says “everyone hates this, so they must be dying for something better.” The other says “everyone hates this, and they’re still not going to leave. So what does that tell me about what they actually need?”

Betting on being the lucky outsider in a mature market is not a strategy. I’ve written about luck before. It’s real, and it matters, but it’s not something you can plan around.

Why the Right Cofounder Matters More Than the Right Feature Set

I spend a lot of time telling founders they probably don’t need a technical cofounder yet, and that searching for one is often a red flag. I stand by all of that. The “idea person looking for a coder” dynamic is almost always broken.

But domain experience is a different story. A partner with deep domain expertise isn’t just bringing an idea. They’re bringing years of understanding that you cannot shortcut. They know the industry from the inside. They know the customers because they’ve been one, or they’ve served hundreds of them. They know the competition because they’ve used every alternative. They know pricing because they know what the market actually bears, not what a spreadsheet suggests.

That’s not an idea person. That’s a market master.

The builder-plus-market-master formula

If I had to design the ideal founding team from scratch, it would be two people:

The Builder. Someone who is great at the craft of making things. Not just code. The whole stack: design, usability, architecture, security, performance. Someone who takes pride in building things that are well-made. Who obsesses over whether the thing they built is actually good to use, not just whether it technically works.

The Market Master. Someone with deep, lived experience in the problem space. They’ve spent years inside the industry. They know the pain points because they’ve felt them. They know the language, the networks, the conferences, the competitors, the pricing expectations. They know which problems people will pay to solve and which ones they’ll just complain about. And because of all of this, they tend to be naturally good at marketing and sales. Not because they studied it, but because they already know how to talk to the people they’re trying to reach.

Put those two together and the roles are clear. The market master knows what to build and who it’s for. The builder knows how to build it and makes it great. Neither one is carrying the other. They’re both bringing something the other literally cannot replicate.

Not a visionary and an executor. Not an idea person and a coder. Two people with deep, different expertise who each bring something the other can’t.

The Real Reason Most SaaS Products Have No Users

I want to be direct about something, because I think the real issue here goes deeper than domain experience as a tactical gap.

Most SaaS products with zero paying users are built by people who are chasing money, not solving problems. I know that’s a broad brush. I know it sounds judgmental. But I see it constantly. People scouring Reddit, joining random Discords, hunting for “SaaS ideas” and “niches” and “recurring revenue opportunities.” The entire orientation is wrong. They’re starting with “how do I extract money from someone” instead of “how do I create something valuable for someone.”

The tricky thing about business is that yes, the point is absolutely to turn a profit. But profit is always a side effect. It’s a side effect of delivering value, of solving a real problem in a way that matters to somebody else, however they define “matters.” You don’t get to skip that step. You don’t get to go straight to the money part. The money comes from the work, and the work is understanding someone else’s problem well enough to actually fix it.

Domain experience isn’t just a tactical advantage. It’s evidence that you actually care about the problem.

That you’ve spent time in it. That you’ve felt it yourself or sat with people who have. That you’re building from understanding, not from a spreadsheet of addressable market sizes.

Why I’m not writing a playbook for faking it

I want to be careful here, because I’m not trying to hand someone a checklist for appearing to care about users. I’m not interested in helping people cosplay empathy so their landing page converts better. If your fundamental orientation is “how do I get people to give me money,” no amount of domain research is going to fix that, and honestly, people can tell. Your users can tell. Your product will tell on you.

What I’m talking about is for people who already think this way. People who actually want to build something good for someone else and are willing to do the work to understand what “good” means from the other person’s perspective. If that’s you, lean into it. Hard. Because that orientation is rare, and it’s the thing that makes the difference over the long run.

How to Know If You Have Enough Domain Experience

If you’re a builder, and I say this as someone who loves building things, the hardest question you can ask yourself is whether you actually have the domain experience to build what you’re building. Not whether you can build it technically. Of course you can. The question is whether you understand the problem well enough that your solution will feel obvious and necessary to the people who have it.

If you’ve been in their shoes for years, you probably do. If you read about the problem last month and thought “I could build something for that,” you probably don’t. That’s okay. It just means you need a partner who does, or you need to go spend real time inside the problem before you write a line of code.

Validating your idea without a technical partner is one approach, and it’s a good one. But validation isn’t just about testing demand. It’s about building the kind of deep understanding that turns a superficial product into one that actually fits.

Success Is Earned

Even if you stumble into something that works without much domain experience, that kind of success isn’t durable. It’s easy come, easy go. You haven’t really learned anything. You don’t understand why it worked, so you can’t repeat it, and you can’t adapt when things change. That’s what happens with trends and fads. The money appears, and then it disappears, and the person is right back to scouring Reddit for the next thing.

They call it work for a reason. And it’s mystifying to me how many people want to make money while avoiding the actual work. The work of understanding someone else’s problem. The work of earning their trust. The work of building something that’s worth paying for because it’s worth using, not because the pricing page is optimized.

Experience is the one thing you can’t fake, you can’t buy, and you can’t shortcut. It’s the EX factor. And if your product has zero users, it might be the thing that’s missing.
