Skip the brainstorming. Start with validated opportunities.

Finding a good micro-SaaS idea is harder than building one. You need the intersection of real demand, manageable competition, and a problem you can actually solve. Most founders waste months on ideas that fail one of these criteria.

To save you that time, I've compiled 100 underserved niches—organized by industry, with competition assessments and validation signals for each. These aren't guaranteed winners, but they're starting points worth investigating.

How to use this list: 1. Scan for industries where you have experience or interest 2. Pick 3-5 niches that resonate 3. Spend 1-2 hours validating each (more on this below) 4. Deep-dive the most promising one

Let's get into it.

Table of Contents

How This List Was Created

I didn't pull these from thin air. Each niche was identified through a combination of:

Research sources: - Chrome Web Store gaps (popular categories with weak solutions) - Reddit and forum complaint threads - Industry-specific job boards (what tasks are people hiring for?) - Failed Product Hunt launches (good ideas, poor execution) - Interviews with founders across industries

Selection criteria: - Search volume indicates real demand - Existing solutions have gaps (based on reviews) - Market isn't dominated by venture-backed giants - Feasible for solo developer or small team

Common Questions

Q: Are these niches validated?

No. These are opportunities, not guarantees. Each requires your own validation before building.

Q: Why micro-SaaS specifically?

Because you can build and launch these solo in 2-3 months, charge $20-200/month, and reach profitability with 50-200 customers. The economics work for independent founders.

Q: What's missing from this list?

AI wrappers—everyone's building those. I excluded oversaturated categories. Also excluded niches requiring significant capital or regulatory expertise.

Q: How did you estimate market sizes?

Combination of: - Search volume extrapolation - Competitor revenue estimates (where public) - Industry reports - Conversations with founders in these spaces

These are order-of-magnitude estimates, not precise calculations.

Q: How often is this updated?

I plan to refresh this annually as markets shift and new opportunities emerge.
