How to Build a SaaS That Doesn't Need Marketing – Just Product Necessity

Forget Growth Hacking

Most SaaS playbooks start with a chapter on marketing. A/B testing landing pages, optimizing conversion funnels, retargeting campaigns. All of that makes sense – if you’re building a product the world doesn’t need.

But what if there’s another way? What if some products just grow because they have to? Not because of clever ads, but because they solve a problem so pressing that users actively seek them out.

This idea isn’t new. But in an era where every startup pours millions into Facebook Ads, it sounds almost heretical. Yet some of the most successful SaaS products of recent years grew exactly like this – organically, quietly, without marketing noise.

Let’s look at how it works. And more importantly – how to tell if your product has what it takes to be “product-necessary,” or whether it’ll simply die without marketing.

What Product Necessity Actually Means

Product necessity isn’t the same as “good product.” Plenty of good products need aggressive marketing. Product necessity means something different: your product solves a problem so acute that users actively search for solutions.

The difference is fundamental. With a regular product, you have to convince people they have a problem. With a product-necessary solution, they already know they have a problem – and they’re looking for someone to help.

Classic example? Invoicing software for freelancers. Nobody needs to convince a freelancer that they need to send invoices. That problem exists objectively, has a deadline (end of the month), and ignoring it has consequences (unpaid invoices, tax problems).

Second example: Slack when it launched. Distributed teams knew email wasn’t working. They were searching for alternatives. Slack didn’t have to explain why team communication matters – it just had to show there’s a better way.

Three Conditions for Product Necessity

After years of observing the SaaS market, I’ve identified three conditions a product must meet to grow without massive marketing. Miss one, and you’ll need marketing. Miss two or more, and you’ll need a lot of marketing.

1. An Existing, Articulated Problem

Users must be able to name the problem. Preferably in a way they’d Google it. “How to invoice as a freelancer” is an articulated problem. “I feel inefficient at work” is not – it’s a feeling, not a problem.

Products solving unarticulated problems require market education. And market education equals marketing.

2. Urgency or Recurrence

The problem must either be urgent (deadline, legal obligation, financial loss) or recur so frequently that people can’t ignore it. Ideally both.

Accounting has both – tax deadline and monthly invoices. Project management has recurrence – every day someone somewhere is managing something. A vacation planning app has neither – you go on holiday twice a year and the deadline is soft.

3. Measurable Results

Users must be able to tell the product works. Not by feeling – by measuring. I saved 3 hours per week. I increased conversions by 12%. I paid $200 less in taxes.

Products with unmeasurable results are prone to churn. Users don’t know if the product helps, so they stop paying. And without retention, there’s no growth.

Anatomy of Organic Growth

When you have a product meeting all three conditions, organic growth looks something like this:

    A[User has problem] --> B[Searches for solution]
    B --> C[Finds your product]
    C --> D[Tries it]
    D --> E[Problem solved]
    E --> F[Stays]
    E --> G[Recommends to others]
    G --> B

Notice what’s missing. There’s no “sees an ad” or “receives an email.” The entire cycle runs on the product solving a real problem and users talking about it.

This isn’t utopia. Basecamp grew this way for years. Notion similarly. Linear. Figma had minimal marketing in its early days – designers simply passed it around because finally there was a tool that worked.

Method

How do you know if your product can grow without marketing? I use a simple framework with five steps.

Step 1: The Articulation Test

Ask ten potential users how they’d describe their problem. Don’t tell them what your product does – just ask about their pain points.

If they use similar words and can clearly describe the problem, you have an articulated problem. If everyone speaks differently or struggles to formulate it, you need market education.

Step 2: The Urgency Test

Ask: “What happens if you don’t solve this problem this month?” If the answer is “not much” or “it’ll be annoying,” you don’t have urgency. If the answer contains words like “fine,” “deadline,” “lose a client,” or “get fired” – you have urgency.

Step 3: The Frequency Test

How often do they encounter the problem? Daily? Weekly? Yearly? Products solving daily problems grow faster. Products solving yearly problems need to remind people they exist – which means marketing.

Step 4: The Measurability Test

Can users state a specific number that improved after a month of using your product? Not a feeling – a number. Time, money, conversions, anything. If not, you have a retention problem.

Step 5: The Word-of-Mouth Test

This is the hardest but most important one. Ask existing users: “Would you recommend our product to a colleague? Why or why not?”

If the answer starts with “yes, because…” followed by a specific reason, you have potential for organic growth. If it starts with “maybe…” or “it depends…”, word-of-mouth won’t work.

Why Most SaaS Products Fail This Test

Let’s be honest: most products won’t meet these conditions. And that’s fine. It doesn’t mean they’re bad – just that they need marketing.

The problem arises when a founder believes their product is product-necessary and refuses to invest in marketing. That’s a recipe for slow death.

Common mistake: “My product is better than the competition, so it’ll sell itself.” It won’t. Better doesn’t mean necessary. Excel is probably worse than many specialized tools – yet half the planet uses it.

Second mistake: “Early adopters love the product, so word-of-mouth will kick in.” Early adopters are a specific group. They love new things. Their enthusiasm may not reflect mainstream market needs.

Third mistake, and this one’s insidious: “We just need more features, then it’ll take off.” More features usually don’t solve the problem. If the core value doesn’t resonate, additional features just dilute the messaging.

When You Actually Need Marketing

Even product-necessary SaaS tools sometimes need marketing. Three situations:

Competitive market. If you’re solving the same problem as ten other tools, you need to differentiate somehow. And differentiation requires communication. And communication is marketing.

New category. If you’re creating something that doesn’t exist yet, you have to teach people the category exists. That’s market education – and therefore marketing.

B2B enterprise. In large companies, decisions take months and involve multiple people. Even if your product is the ultimate solution, you need to get it in front of decision-makers. And that doesn’t happen without marketing.

Generative Engine Optimization

In the era of AI search engines and generative answers, the rules are changing. ChatGPT, Perplexity, and similar tools don’t present users with ten blue links – they give them direct answers. And those answers emerge from synthesizing available information.

What does this mean for SaaS products without marketing?

First: your product must be visible in the data that AI models learn from. This paradoxically requires some form of “marketing” – content, reviews, mentions in communities. AI can’t recommend a product it doesn’t know about.

Second: quality and consistency of information is critical. If contradictory or outdated information exists about your product, AI might synthesize it incorrectly. Your product then appears unreliable or confusing.

Third – and this is key: human judgment and context remain irreplaceable. AI can recommend a category of solutions, but specific choices often require nuances machines can’t capture. Communities, direct recommendations, personal experiences – these are channels AI hasn’t fully replaced yet.

The ability to critically evaluate automated recommendations is becoming a meta-skill. A user who blindly follows the first AI answer might miss a better solution. And a SaaS product that relies only on AI visibility without building real community risks being quickly overshadowed by competitors.

Automation-aware thinking – the awareness that automated systems have limits – is a skill of the future. For SaaS creators, this means: don’t optimize just for algorithms, build real value for real people.

The Story of a Product That Didn’t Need Marketing

A friend of mine launched a simple tool for Czech e-commerce stores three years ago. It solved one specific problem: automatic generation of XML feeds for price comparison sites. Boring problem, but real.

No marketing. No ads. One blog post explaining how XML feeds work. That was it.

First year: 200 paying customers. Second year: 600. Now over a thousand and still zero in the marketing budget.

Why did it work?

Articulated problem: “I need an XML feed for Heureka” is something e-shop owners actually Google. Urgency: without feeds you’re not on comparison sites, without comparison sites you have no traffic, without traffic you have no sales. Recurrence: feeds need updating, products change, prices change. Measurability: either the feed works or it doesn’t – it’s binary.

Of course, he’s lucky that competition in his niche is limited. But even if it was bigger, the foundations for organic growth would be laid correctly.

The Dark Side of Product Necessity

It’s not all roses. Products growing purely organically have their problems.

Slow growth. Organic growth is slow. If you need to scale quickly (say, because of investors), you won’t manage without marketing. Word-of-mouth has its limits.

SEO dependency. Many organically growing SaaS products depend on search engines. What happens when Google changes its algorithm? What happens when AI search takes over? Diversifying sources matters.

Limited control. You can’t influence when and how fast you’ll grow. You can’t launch a campaign and watch conversions rise. You’re dependent on users finding your product themselves.

Feedback loop paradox. When you don’t do marketing, you have less data about what works. You don’t know what messaging resonates because you have no messaging. This complicates any future marketing efforts.

My cat just walked in and lay down on my keyboard. British lilac. Apparently he thinks the article is too long. Maybe he’s right – but we’re not done yet.

The Hybrid Approach

Pure organic growth is an ideal, but most successful SaaS products use a hybrid approach. The foundation is product necessity, but they supplement it with targeted marketing activities.

Example: Notion. Basic growth was organic – designers and product managers passed it around among themselves. But Notion also invested in a template gallery, influencer partnerships, and content marketing. It wasn’t “either-or,” it was “both.”

    end
    A --> B
    B --> C
    B --> D
    B --> E
    C --> B
    D --> B
    E --> B

The hybrid approach requires discipline. It’s tempting to shift focus to marketing when organic growth slows. But if basic product necessity doesn’t work, marketing won’t save it – just delay the inevitable.

Practical Checklist

Before we wrap up, here’s a summary in checklist form. Go through it before deciding whether your SaaS can grow without marketing.

Problem Articulation

• Can potential users clearly name the problem?
• Do they use similar words when describing the problem?
• Are they actively Googling solutions to this problem?

Urgency and Frequency

• Does the problem have a deadline or financial consequences?
• Do users encounter it at least weekly?
• Is ignoring the problem costly?

Measurability

• Can users quantify the benefit after a month of use?
• Is there a clear success metric?
• Is the “before and after” difference visible?

Word-of-Mouth Potential

• Do existing users recommend the product spontaneously?
• Can they articulate a specific reason for recommending?
• Is there a community where the problem is discussed?

If you have more than 10 checks, your product has a chance to grow organically. If fewer than 6 – invest in marketing.

Final Thoughts

Product necessity isn’t a strategy – it’s a property. Either your product has it or it doesn’t. You can’t add it with marketing, you can’t simulate it with growth hacks.

What you can do: choose a problem that has potential for product necessity. That’s a strategic decision you make at the beginning. Not at the end when the product is already built.

Most founders choose problems that personally interest them. That’s understandable – you’ll work on it for years, it should be enjoyable. But personal interest doesn’t correlate with product necessity. A problem that fascinates you might not be a problem people actively solve.

The ideal is an intersection: a problem that interests you AND meets the conditions for product necessity. Such intersections aren’t common. But when you find one, you have a chance to build something that grows on its own.

And that is, honestly speaking, the most beautiful thing in the SaaS world. A product that doesn’t need to shout for attention. A product that people find on their own because they simply need it.

It’s not easy. It’s not common. But it is possible.

And now if you’ll excuse me – someone here is demanding dinner and has four legs and a very strong opinion about when eating time should be.
