Vertical SaaS: Why Niche Products Win in the Nordics

Vertical SaaS is software built for a single industry or profession, like dental clinics, electricians or online fitness coaches, instead of for every business at once. In the Nordics, vertical products often beat big international tools because each market is small and shaped by its own language, regulation and local systems, which global vendors rarely prioritize. That limits how big you can get in one country, but it makes it far easier to become the default choice in a well-defined niche.

I write this as a developer. My examples are Danish and Nordic, but the same logic holds across most of Europe, where each country is a small market with its own rules.

The short answer: vertical vs horizontal SaaS

The difference is who the product is for. Accounting software or a project management tool works for an accountant, a hair salon and a software company alike. A vertical product is built for one of them, so it already speaks their language and knows their rules and workflows.

My rule of thumb: if you can name the industry, list your first 20 prospects by name and explain which workflow your product takes over, vertical SaaS is often the safest bet for a small European startup. If you can't yet, it's too early to build. For the full path from idea to paying customers, see my guide to building a SaaS from scratch.

What makes a product vertical (and what doesn't)

A vertical product starts from an industry's working day, not from a technical feature. It knows the documents your customer has to produce, the rules they follow and the systems they exchange data with. The customer doesn't have to bend a generic tool to fit their trade, because that work has already been done.

Well-known examples include Toast for restaurants and Procore for construction. In the Nordics, the Danish software company EG has built its whole business around the idea: it describes its products as software built for your industry and reports more than 44,000 customers.

Remotefitness is a much smaller example of the same principle. It wasn't built as a general booking or payment tool, but for one profession: fitness coaches who train clients online. The point of a vertical product is that the customer doesn't have to stitch several generic tools together to cover one workflow. I've written about the build in from idea to SaaS: choices and priorities.

Three things often get mistaken for vertical SaaS:

• Custom software for one client. Building a system for a single company is bespoke development. Vertical SaaS is one product sold to many companies in the same industry.
• A generic product with an industry landing page. A CRM with a page titled "CRM for real estate agents" is still horizontal if the product behind it is the same.
• A product with few features. Vertical products tend to start narrow, then grow wider within their industry, adding scheduling, payments, messaging and reporting in one place.

Why niche products win in the Nordics (and much of Europe)

It's not that Nordic businesses love niche software more than anyone else. The conditions that make a market unattractive to a global vendor just happen to be the ones that leave room for a local product.

Small markets keep the giants away

Denmark has just over 6 million residents, and the Nordic region as a whole had 28.3 million registered residents on 1 January 2025. To a US SaaS company, a Danish industry with a couple of thousand businesses is a rounding error. It rarely gets a Danish translation, support staff who understand the trade, or integrations with the systems local companies actually use. A local niche product can fill that gap.

Local rules work like a moat

Many industries run on national rules: collective agreements and pay supplements in the trades, record-keeping rules in healthcare, holiday pay schemes and bookkeeping requirements. One concrete example: under Danish bookkeeping law, a digital standard bookkeeping system marketed in Denmark must be registered with the Danish Business Authority (page in Danish). For a Danish product, that's simply part of the job. For a foreign vendor, it's extra work for a small market.

E-invoicing adds another layer. Since the EU's ViDA package entered into force in April 2025, member states can introduce mandatory domestic e-invoicing under certain conditions, so the details are likely to keep differing from country to country. Add national login systems like MitID in Denmark and BankID in Sweden and Norway, plus local accounting tools, and the small differences add up to a real reason for a business to pick a local system.

Word travels fast in a small industry

In a small country, an industry is a small world. There are usually one or two trade associations, a couple of trade shows, a few specialist magazines and a handful of suppliers everyone uses. That makes the first sales slow, because you have to earn trust. The sales after that get cheaper: a happy customer tells a colleague, and a good reputation travels fast. A horizontal product has to buy its visibility while competing with the whole world.

Buyers want someone who gets their work

In my view, many Nordic small businesses in traditional industries would rather pay a little more for a system in their own language, with support that understands their day, than save money on an international tool they have to configure themselves. That's especially true where the owner is out on jobs all day and has no time to become a part-time system administrator in the evening.

How to build a vertical SaaS in 7 steps

Order matters. The classic mistake is starting at step 6 before steps 1-5 are in place.

1. Pick an industry you can reach. The best niche is one you've worked in, or where you know people who will pick up the phone. Without access to customers, you learn the industry's language slowly and every sale gets expensive. If you need a starting point, browse my list of SaaS ideas for niche markets.
2. Shadow a working day instead of sending a survey. Sit with three to five businesses and watch where the time goes: spreadsheets, double data entry, paper forms and phone calls. Ask what they pay for today, in money and in hours. That's where your product should start.
3. Find what international tools can't do. It might be a national rule, a local integration, an industry term or a workflow that generic tools expect the customer to build themselves. If you can't find anything, there may be no room for a vertical product.
4. Size the market. Count the businesses by industry code (NACE codes in the EU) in your national business register, then cross-check with association membership numbers or trade show exhibitor lists. Finally, work backwards from the revenue you need, as in the example below.
5. Get paid before you code. Get five to ten businesses to agree to a specific price, ideally with a prepayment or a signed letter of intent. My guide on how to validate a SaaS idea before writing any code covers the details.
6. Build the narrowest version that takes over one workflow. Not the whole industry system, just one job done so well that the customer stops opening the spreadsheet. For help deciding what to leave out, see how to scope an MVP.
7. Sell where the industry gathers. Associations, specialist magazines, trade shows, wholesalers and advisers like accountants usually beat ads. Give your first customers a good price in return for using them as references. In a small industry, one well-known customer is worth more than an ad campaign.

Is a small market big enough?

The most common objection to a Nordic niche is that the market is too small. That depends on what you want from it. If you plan to raise venture capital and build a billion-euro company, one industry in one Nordic country won't get you there. If you want a healthy business that pays you and a small team, it can be plenty.

Here's an example with round numbers:

• An industry has 2,000 businesses in your country.
• Over a few years, you win 10% of them: 200 customers.
• Each pays €100 a month, excluding VAT.
• That's €20,000 in monthly recurring revenue (MRR), or €240,000 a year.

These figures are an illustration, not a forecast. The point is that you don't need thousands of customers if your price matches the value you create. €100 a month is a lot for a generic tool and very little for a system that replaces spreadsheets, paper forms and two other subscriptions.

At the same time, watch how many customers cancel and what each new one costs to win. In a small market you can't afford to burn through prospects, because there's no endless supply of new ones. I explain how these numbers connect in SaaS metrics explained.

Plan for the ceiling

You will hit a ceiling, and it's better to know where it is up front. Once you hold a large share of an industry in one country, there are two usual ways to grow: into neighboring countries, where the industry looks similar but rules and language differ, or into an adjacent industry with the same needs.

Both get cheaper if the product is built for it. As a developer, I recommend storing text, currency, VAT rates and date formats as settings from day one, even if you only sell in one country. It costs very little early on and a lot to retrofit. Keep industry-specific and country-specific rules in a separate module, so adding a new country doesn't mean touching the rest of the code.

When a niche product is the wrong bet

A niche product isn't always the answer. These are the situations where I'd think twice:

• The industry doesn't buy software. Some sectors run on thin margins with no habit of paying for systems. That can change, but being the one who changes it is expensive.
• An industry system already exists and customers like it. Then you need to be clearly better at something specific, not just newer. Switching industry systems is painful, and that protects your competitor too.
• You want to raise venture capital. Many investors look for markets that can become very large. A Nordic niche can be a good beachhead, but your plan to grow beyond it has to be credible from the start.
• The need is the same across industries. If the hair salon, the accountant and the carpenter all have exactly the same problem, a horizontal product usually fits better, and one probably exists already.

And an honest note from someone who builds software for a living: if an existing industry system covers most of what you need, buying it is almost always cheaper than hiring a developer like me to build a new one.

Next steps

Run through the checklist below before you spend money on development. If you can't tick off most of it, spend more time with customers before you build.

Once the list holds up, the next step is a first version that does one workflow well. This is how I approach SaaS development for founders: a fixed-price discovery phase, direct contact with the developer who writes the code, and code you own from day one.

Frequently asked questions

Is vertical SaaS the same as micro-SaaS?+

No. Vertical describes who the product serves, while micro-SaaS describes the size of the business behind it. A micro-SaaS is usually a small product run by one person or a tiny team, and it can be vertical or horizontal. Many micro-SaaS products are vertical, since a narrow niche is easier to reach without a big marketing budget, but a vertical product can just as well grow into a large company.

Can I build a vertical SaaS for the Nordic market from outside the Nordics?+

Yes, but expect to work harder for trust. Buyers in traditional Nordic industries usually expect the product, invoices and support in their own language, plus integrations with local accounting and login systems. A local partner, such as a reseller, an industry adviser or a co-founder from the trade, can close that gap faster than translation alone.

Do I need to come from the industry myself?+

No, but you need close access to people who do. A niche product is strongest when someone who knows the industry from the inside works alongside someone who can build and sell software. If you're an outsider, bring two or three businesses from the industry in early, for example as paying pilot customers with a direct line to you. Without that contact, you risk building what you think the industry needs.

How much does it cost to build a vertical SaaS?+

The cost depends on scope, not on the product being vertical. A first version costs roughly the same as any SaaS MVP of similar size. What can make a vertical product more expensive is integrating with industry systems and getting local rules right from day one. Start with one workflow, get a fixed price for it, and budget for the rest once paying customers have confirmed the direction.

How do I check whether an industry already has a dominant system?+

Ask prospects what they use today, then look at the trade association's supplier list and the exhibitor lists from industry trade shows. Search for industry terms combined with "software" or "system" in the local language as well. If you find one, talk to some of its customers about what's missing. Unhappy users of a dated industry system are often the best first customers for a new one.
