What is a SaaS company – really?
The usual explanation: a SaaS company sells software as a subscription service over the Internet. The customer pays per month or year and does not have to install anything. Slack, Spotify, HubSpot – all are SaaS.
That explanation is true but misses the point. What makes SaaS its own business model isn't the technology – it's the revenuerecurrent. You don't sell a product once. You deserve the same customer every month, over and over again. This is why investors love SaaS: predictable revenue (MRR and ARR) can be counted on and value built around.
The flip side of the same coin: if the customer doesn't experience value every month, they quit. A SaaS company is therefore not “an app with a login” – it is a machine for creating and maintaining value over time. Everything below is based on that.
Step 1: Find the right problem – and prove it exists
The most common cause of death for startups is not bad code. It's that you build something nobody wants. Before you write a line of code or ask an AI builder thatLovableassemble a prototype for you - validate. Just because the idea already exists doesn't mean you should give up. The question is whether you can make it noticeably better for a clear target group. If you can do it - drive.
But here's where most people make a mistake worth stopping at: they ask"Would you pay for this?"That's the wrong question. People say yes to be nice, and then they don't buy anything. Hypothetical money is free to pledge.
Instead, ask about what they are already doing today:
Talk to 20-50 people in your target audience - but talk aboutthe current situation, not about your idea.
"How do you solve this problem today?" "What does it cost you in time or money?" "When was the last time you did that?"
Look for people who are already paying for an inferior solution or building ugly workarounds in Excel. That is the buy signal.
The strongest evidence is not words, but action: a waiting list with real email addresses, a letter of intent (LOI) from a company, or someone paying in advance before you've finished building. Do you get people topick up the walletbefore the product exists - then you have something. Do you only get nods and "exciting!" - keep digging.
Step 2: Build an MVP that's actually likeable
An MVP (Minimum Viable Product) is the simplest version that solves the core problem. The goal is to get out quickly and gather feedback—not to build the perfect product.
But the "minimum" has killed more startups than it has saved. An MVP that's buggy and ugly doesn't collect useful feedback—it collects disappointed users who never come back. You are then not testing your idea, you are testing your QA. How would you have experienced a new launch that just crashes?
Our advice: think betterSLC – Simple, Lovable, Complete. Buildfewerfeatures, but let the features you invest in work 100% and look nice. Slim and full beats wide and ragged every time.
Schedule:aim for 4-12 weeks. If it takes longer, you've probably built too wide - cut away.
Popular tech stacks in 2026:
Next.js + Supabase + Stripe– fastest for solo founders. You can have payments, database and login up and running in days, not months.
React + Node.js + PostgreSQL– more flexible and easier to scale teams around, but requires more setup.
Rule of thumb for technology: choose boring, proven technology that you can actually find developers for. Cool frameworks don't impress anyone if the product never gets finished.
Step 3: Pricing – charge more than you dare
SaaS pricing is a separate topic, but the basic models are these:
Freemium:free basic version + paid level. Good for products with viral potential, expensive if the "free users" never convert.
Trial:14-30 day free trial period, preferably without a credit card. Reduces friction to test.
Per user (per seat):paid per user per month. Suitable for B2B where more users = more value.
The most important principle:price according to value, not according to your own uncertainty.Almost all founders set the price too low because they compare it to what it "cost to build" instead of what it's worth to the customer. It is always easier to lower a price than to raise it. Start higher than feels comfortable.
Two concrete tricks that most people miss:
Offer annual payment.It gives you cash flow in advance and customers who stay longer. Give a discount (eg two months free) and many will choose it.
Keep the number of levels down.Three price levels are enough. More just creates decision anxiety.
And learn the four numbers that determine whether the company survives:MRR(monthly recurring income),churn(how many resign),CAC(how much it costs to acquire a customer) andLTV(what a customer is worth over time). A general rule of thumb: LTV should be at least three times CAC, and you want to recoup the cost of a new customer within a year. If you don't pass that test, growth doesn't matter - you just bleed faster.
Step 4: Corporate form and law in Sweden
This is the part where Swedish guides tend to be vague. Here are the actual numbers and rules for 2026.
Limited company (AB)
The most common choice for SaaS startups, as it provides limited personal liability and is perceived as serious by customers and investors. What it actually costs to start:
Share capital:at least SEK 25,000 (reduced from SEK 50,000 since 2020).
Registration fee at the Swedish Companies Registration Office:SEK 2,200 via the web.
Total:around SEK 27,000–29,000 to get started.
Common misunderstanding: the share capital isnota cost and not locked in an escrow account. It is the company's starting capital and can be used as working capital from day one after registration.
Tax and VAT
F tax:apply to the Swedish Tax Agency - it's free.
VAT registration:required when your turnover exceeds SEK 80,000 per year. Swedish VAT is 25%.
VAT on SaaS across borders- this is where many people get lost: if you sell to companies within the EU, reverse tax liability normally applies (the customer reports the VAT). If you sell digital services to private individuals within the EU, you must chargeof the customer's countryVAT and report via OSS (One Stop Shop). Build it into your payment solution from the start – it's a nightmare to correct afterwards.
GDPR and agreements
GDPR:most SaaS handle personal data. You need a privacy policy, control of where the data is stored (within the EU is easiest - transfer to the US requires you to lean on the right regulations) and personal data processor agreements (PUB agreements) with the subcontractors that store data for you.
Terms and EULA:produce proper terms of use. Use a lawyer or a reputable template service – don't copy a competitor's terms straight out.
This is not legal advice, but a map. Before you sign anything important: talk to a lawyer who knows your specific situation.
Step 5: Distribution and Growth
Building the product isn't the hard part – getting someone to find it is. The best SaaS companies build distribution into the product itself:
Product-led growth (PLG):the product promotes itself by users inviting others (Slack, Notion). Works best when the product is used together with others.
Content marketing + SEO:long-term organic traffic. Takes time to build, but never stops delivering once it's rolling.
Cold outreach:direct contact via LinkedIn and email. Honestly: the conversion rate is low and it requires volume and persistence. Works for B2B with high order value, rarely for cheap products.
Partners and integrations:build your product into other people's ecosystems and borrow their user base.
The most important advice:pick one or two channels and get really good at them.New founders spread across six channels at once and become average on all of them.
Common mistakes to avoid
Build too many features from scratch.Every feature you add is something you have to maintain, support and explain. Slim and sharp wins.
Ignore churn.Filling a bucket with holes in the bottom is pointless. 5% monthly churn means you lose over half your customer base in a year. Measure and act early.
Price too low.Low price signals low quality, attracts the wrong customers and makes it impossible to afford support and development.
Skip onboarding.Most cancellations happen in the first week, before the customer even understands the value. A good onboarding is not a luxury – it is the difference between a customer and a lost one.
