15+ Micro SaaS Ideas: Real Examples from Solo Founders with $10K-$100K+ MRR

No theoretical ideas, just real Micro SaaS products that actually work. With links, revenue numbers, and founder learnings. From $10K MRR to $3M+ per year – all bootstrapped.
Note: All revenue numbers mentioned are based on public statements from the founders (e.g., on Twitter/X, in podcasts, or on their websites) at the time of my research. These numbers may have changed.
Why This Post Is Different
The internet is full of "50 SaaS Ideas for 2026" lists. The problem? Most are theoretical. Nobody built them. Nobody made money with them.
This post is different.
Here you'll find real Micro SaaS products from real founders. With verified revenue numbers. With links to the products. With the stories behind them.
No fantasy ideas. Only things that actually work.
What Is Micro SaaS Anyway?
Micro SaaS is Software-as-a-Service on a small scale:
- Small: 1-3 person team (often solo)
- Focused: Solves ONE specific problem
- Bootstrapped: No VC money needed
- Profitable: $5K-$250K MRR is the sweet spot
The advantage? You don't need millions in funding. You don't need 50 employees. You just need a problem you solve better than the competition.
And the numbers speak for themselves:
According to a MicroConf survey:
- 39% of all Independent SaaS founders are solo
- 42% of companies with $1M+ revenue are run by solo founders
- The "sweet spot" is $5K-$50K MRR
The Most Successful Micro SaaS Examples
1. Nomad List – $1.5M+ ARR
Founder: Pieter Levels (@levelsio) Link: nomadlist.com What it does: City rankings for remote workers and digital nomads
Pieter Levels is widely regarded in the community as one of the most well-known Micro SaaS founders. He started Nomad List in 2014 as part of his "12 Startups in 12 Months" challenge – as a spreadsheet.
Today the platform makes over $1.5M ARR. Solo. No employees. With a tech stack of vanilla PHP, jQuery, and SQLite.
The learning: You don't need fancy technology. You need a problem you understand because you have it yourself.
2. Photo AI – $132K MRR
Founder: Pieter Levels Link: photoai.com What it does: AI-generated photos of yourself
Yes, Pieter again. But this shows his system: Start many projects, see what works, then scale.
He launched Photo AI in 2023. 18 months later: $132K MRR. The first version was "so bad," as he himself says. But he launched anyway and iterated.
The learning: Launch at 70%, not 100%. You learn more from real users than from months in isolation.
3. Remote OK – $42K MRR
Founder: Pieter Levels Link: remoteok.com What it does: Job board for remote jobs
The world's largest remote job board. Started in 2015, grown through SEO and the Nomad List community.
The learning: If you already have an audience, build products for that audience.
4. Carrd – $1.5M+ ARR
Founder: AJ (@ajlkn) Link: carrd.co What it does: One-page website builder
AJ originally wanted to build a Squarespace competitor. Then he realized: He couldn't. So he reduced the scope – to simple one-page websites.
This limitation became his biggest differentiator.
Today Carrd hosts over 4 million websites. The price? $19 per year. Still: $1.5M+ ARR.
The learning: Sometimes less is more. Find a niche within a niche.
5. Testimonial.to – $840K+ ARR
Founder: Damon Chen (@damengchen) Link: testimonial.to What it does: Collect and embed video testimonials
Damon reportedly had four failed startups before Testimonial.to worked. He launched it on Product Hunt at the end of 2020 and reached $200K ARR within a year.
Today Fortune 500 companies use his tool. All bootstrapped. All solo.
The learning: Failure is part of the process. Damon needed five attempts.
6. Senja – $1M ARR
Founders: Wilson Wilson & Olly Meakings Link: senja.io What it does: Collect and display testimonials
Two people. Remote. Met online. 3 years and 9 months to $1M ARR.
Their secret? Build in public. Every embedded testimonial widget became free marketing.
The learning: Build features that market themselves.
7. Bannerbear – $10K+ MRR
Founder: Jon Yongfook (@yongfook) Link: bannerbear.com What it does: API for automatic image generation
Jon also did the "12 Startups in 12 Months" challenge. Bannerbear wasn't his first attempt – but the one that worked.
He documented how he went from $0 to $10K MRR. Transparent. Honest. With all the mistakes.
The learning: The path to product-market fit is rarely linear. Iterate based on real feedback.
8. ConvertKit – $3.6M MRR
Founder: Nathan Barry (@nathanbarry) Link: convertkit.com What it does: Email marketing for creators
Nathan started ConvertKit in 2013 as part of a public challenge: "$5K MRR in 6 months." He documented everything.
12 years later: $3.6M MRR. Completely bootstrapped.
The learning: Set public goals. The accountability helps.
9. Prerender.io – $2.5M ARR
Founder: Todd Hooper Link: prerender.io What it does: SEO for JavaScript websites
Todd built Prerender because his own projects weren't ranking on Google. A classic "scratch your own itch" case.
He built it on the side until the profit was big enough to quit his job.
The learning: Build on the side first. Only quit when it's working.
10. Tweet Hunter / Taplio – $60K+ MRR
Founder: Tibo (@taborovak) Link: tweethunter.io / taplio.com What it does: Twitter/LinkedIn growth tools
Tibo understood that creators need tools for their own platforms. Tweet Hunter helps with Twitter growth, Taplio with LinkedIn.
Both tools combined: $60K+ MRR.
The learning: Creator economy is a growing market. Tools for creators sell.
11. Newoldstamp / MySignature – $700K ARR
Founder: Vol Link: newoldstamp.com / mysignature.io What it does: Email signature generator
Vol worked at a TV manufacturer and was annoyed by manually creating email signatures for every employee.
With $10K in savings, he reportedly quit and built Newoldstamp. Today: over 500K users and $700K ARR.
The learning: The best ideas come from real problems in your everyday life.
12. Revid.ai
Founder: Tibo Link: revid.ai What it does: AI-generated short videos
Users input an idea, the AI generates script and video. Perfect for TikTok, Reels, Shorts.
The learning: AI wrappers for specific use cases work – if the use case is clear enough.

The Patterns That Repeat
After analyzing these success stories, patterns emerge:
1. Scratch Your Own Itch
Almost every successful Micro SaaS solves a problem the founder had themselves:
- Pieter was a digital nomad → Nomad List
- Todd's sites weren't ranking → Prerender
- Vol hated manual signatures → Newoldstamp
Takeaway: Build something you would use yourself.
2. Start Small, Really Small
- Carrd: "Only" one-page websites
- Testimonial.to: "Only" video testimonials
- Bannerbear: "Only" automatic image generation
Takeaway: The narrower the focus, the clearer the value proposition.
3. Build in Public
Senja, ConvertKit, Bannerbear – all built publicly. This creates:
- Accountability
- Early feedback
- Free marketing
Takeaway: Share your progress. The community helps.
4. Multiple Attempts
- Damon Chen: 4 fails before Testimonial.to
- Pieter Levels: Has reportedly started 70+ projects"
- Jon Yongfook: 12 Startups in 12 Months
Takeaway: The first attempt rarely works. Keep going.
5. Simple Tech Stack
Pieter uses PHP and jQuery. AJ built Carrd solo. No React, no Kubernetes, no microservices.
Takeaway: Your productivity > "best" technology.
How to Find Your Micro SaaS Idea
1. Document Your Frustrations
For one week: Write down every time you think "There should be a tool for this" or "This process is annoying."
2. Check for Competition
- No competition = probably no market
- Competition exists = validation that people pay
- Your differentiator: niche, price, or UX
3. Validate Before Building
- Find 10 people with the problem
- Ask if they would pay
- If "maybe" → Red flag
- If "how much?" → Green light
4. Start with MVP
- 4-8 weeks build time max
- One core feature that works really well
- Launch at 70%, not 100%
