What is a Micro-SaaS and Why You Should Care?

Over the past few years, we’ve seen more and more micro-SaaS solutions appearing on the market. But what exactly is a micro-SaaS? And how does it differ from traditional SaaS? Let’s break it down.

What is SaaS?

Before diving into micro-SaaS, let’s clarify SaaS itself.

SaaS (Software as a Service) is a subscription-based model where users pay monthly or annually to access the latest version of software hosted in the cloud.

Unlike the old days of buying a license for each update, SaaS ensures you always have the most up-to-date version, accessible anytime, anywhere, from a browser or mobile app.

What is a Micro-SaaS?

A micro-SaaS is essentially a smaller, niche-focused version of a SaaS product.

Instead of targeting a massive market, a micro-SaaS addresses a particular problem for a specific group of users.

👉 It may only offer one or two key features, but it executes them exceptionally well.

Many micro-SaaS projects actually start as secondary features of larger SaaS platforms, then evolve into standalone products with more depth and specialization.

How Many People Do You Need to Build a Micro-SaaS?

Unlike traditional SaaS projects that may require large teams, a micro-SaaS can often be developed by just 2–3 skilled developers working in sync.

Why You Should Care About Micro-SaaS

The micro-SaaS space is booming.

There are thousands of small but profitable products out there generating recurring revenue by solving very niche problems.

💡 Typical revenue: between €1,000 – €10,000 per month.
💡 Typical subscription price: rarely above €10/month.

Many developers create, grow, and then sell their micro-SaaS on specialized marketplaces (especially popular in the US). Once sold, they move on to building the next one.

The biggest advantage? Even if your niche is small, at a global scale, your potential market is surprisingly large.

Can a Micro-SaaS Grow Big?

Yes! While most remain small and straightforward, some micro-SaaSs evolve into full SaaS platforms with much larger revenues.

But even as a side project, generating €5K–€10K per month in recurring revenue is enough to give you financial freedom, or even fund your dream lifestyle while traveling the world.
