What Is SaaS and Should You Build One? The Starting Point

You've probably heard the term SaaS everywhere. Build a SaaS, launch a SaaS, scale a SaaS. But what does it actually mean? And more importantly - is it something you should spend your evenings and weekends on?

SaaS in simple words

SaaS stands for Software as a Service. Instead of buying software once and installing it on your computer, users pay a recurring fee - monthly or yearly - to access it through a web browser. Think of tools like Notion, Slack, or Mailchimp. You don't install anything. You open a browser, log in, and it works.

Why does this model matter for solo founders? Because recurring revenue means predictable income. You don't need to find new customers every month to survive. If someone subscribes in January, they keep paying in February, March, and beyond. That's the power of SaaS.

Is it worth building one?

Honest answer? It depends. But let me share why I think it's one of the best paths for someone who wants to build something of their own.

The good parts:

If you can code, you skip the most expensive part - hiring a developer. But even if you're not technical, AI tools like Claude or ChatGPT can help you design, plan, and even generate working code. The barrier between "idea" and "product" has never been thinner.
The initial cost is close to zero. A domain, hosting, maybe a few API subscriptions. You can start for less than $50/month.
You can build it alone, in your spare time, without quitting your job.
Once it works and people pay, it generates income even while you sleep.

The hard parts:

Building the product is only 30% of the work. The other 70% is marketing, sales, and talking to customers.
It takes time. Months before the first paying customer. Sometimes longer.
You need to solve a real problem. Not an imaginary one. Not one that sounds cool on paper.

Where to find problems worth solving?

This is the most important question. Forget about building the next big platform. Start small. Start with frustration.

Look at your own daily life:

What repetitive task annoys you at work? Is there a spreadsheet you update every week that could be automated?
What process at your company is broken? Manual invoicing, scheduling, reporting?
What do you Google every month because there's no good tool for it?

Look at people around you:

Talk to friends who run small businesses. What do they complain about? What takes too much time?
Browse Reddit, Twitter, or niche forums. People constantly describe problems. Most of them are solvable with a simple web app.
Check freelancing platforms. What tasks do people hire others to do repeatedly? If it's repetitive, it can probably be automated.

A few real examples of everyday problems turned into SaaS products:

A small team was drowning in sticky notes and scattered spreadsheets. They needed one place to track tasks and deadlines. That's a simple project management tool.
A marketing agency was logging into five different social media accounts every day to post content. They needed a single dashboard to write, schedule, and publish posts across Facebook, Instagram, and LinkedIn. That's a social media automation tool.
A freelancer was tired of manually sending invoice reminders. That's an invoicing automation tool.
A teacher needed to schedule parent-teacher meetings without 50 back-and-forth emails. That's a booking system.

None of these required groundbreaking technology. They required noticing a problem and deciding to fix it.

How to start? Step by step.

You don't need a perfect plan. You need momentum. Here's a practical path:

1. Pick one problem. Not three. One. The more specific, the better. "A tool for managing tasks" is too broad. "A tool that helps freelance photographers send proofing galleries to clients" is specific enough.

2. Validate before you build. Talk to 5-10 people who have this problem. Ask them how they solve it now. Ask if they would pay for a better solution. If most say "I'd just use a spreadsheet" - that's a signal. If they say "I've been looking for something like this" - you might be onto something.

3. Build the simplest version possible. Not a full product. A Minimum Viable Product - MVP. What is the one core feature that solves the problem? Build only that. No settings page, no admin panel, no dark mode. Just the core.

4. Choose your tools and start. If you can code, use what you already know - don't learn a new framework just for this. If you're not technical, use AI assistants to help you build. Speed matters more than technology choice at this stage.

5. Launch ugly. Your first version will look rough. That's fine. Ship it. Put it in front of real users. Their feedback is worth more than 3 extra months of polishing.

The biggest mistake

Building in isolation for months without showing it to anyone. I've done this. Twice. Spent over a year on a product, only to realize nobody wanted it in that form.

The fix? Build in public. Share your progress. Get feedback early and often. It's uncomfortable, but it's the difference between a product people use and a project that collects dust.

So, should you build a SaaS?

If you have an itch to create something of your own - yes. Whether you're a developer or someone with a great idea and willingness to learn, the barrier to entry has never been lower. Your first SaaS probably won't make you rich. It might not even make money. But it will teach you things no course or tutorial ever could: how to find customers, how to talk about your product, how to make decisions on your own.

And who knows - maybe that small tool you build to solve one annoying problem will be the one that sticks.

Start small. Solve real problems. Ship fast. Learn along the way.
