After researching 100+ micro-SaaS opportunities, these 7 patterns kept repeating

I’ve spent the last few months researching micro-SaaS opportunities in a more structured way than I usually see online — pricing pages, demand signals from communities, revenue potential, implementation scope, and whether the thing actually looks buildable for a solo founder.

After going through 100+ of them, a few patterns kept coming up.

1. The best opportunities usually aren’t new markets

Most of the stronger ideas were wedges into existing categories, not brand-new categories. Demand was already there. The problem was already understood. The opportunity came from better positioning, simpler execution, or pricing for a narrower customer.

2. Markets with a handful of competitors were usually the most interesting

One thing I kept noticing: the strongest opportunities often sat in markets with a few real players, but no obvious winner. Not empty markets, and not overcrowded ones either.

3. A lot of the wedge came from “specific buyer + simpler pricing”

Again and again, the opportunity wasn’t “invent something new.” It was “take a bloated tool, narrow the use case, and make the pricing make sense for a smaller customer.”

4. Small buyers still look more neglected than people assume

Freelancers, agencies, single-location businesses, lean teams — these segments looked “served” on the surface, but often not served well. A lot of software is either too enterprise-y or too lightweight to justify long-term spend.

5. The buildable ideas usually fit in a 4–6 week MVP range

The best ideas for solo founders usually had enough depth to charge for, but not so much surface area that they’d take 4 months to get live. One core workflow, working auth, billing, and a clear value prop was usually enough.

6. Vertical SaaS looked harder to sell, but often better long-term

The upside in vertical tools often looked stronger than expected. Harder to break into, yes — but once you solve a specific workflow for a specific industry, it’s harder to get displaced by generic tools.

7. Devtools were common, but not always attractive businesses

A lot of devtool ideas looked cool, but not all looked great commercially. If the user is technical enough to build around the problem, that changes how they value your product. The more interesting ones often had a business owner or team lead as the actual buyer.

Big takeaway:

The best micro-SaaS opportunities I found were usually pretty boring. Existing market, expensive incumbents, clear pain, and a customer segment nobody was really focused on.

I’ve been turning these into full reports for a project I’m building called MicroGaps. A few are free if anyone wants to see the format.

Curious if others here have seen the same patterns.
