How Solo Developers Find Million-Dollar SaaS Ideas: 8 Real Examples

Every successful SaaS started with an idea. But where do the best ideas actually come from?

If you're a solo developer looking for your next profitable SaaS idea, the answer isn't what most people think. It's not about brainstorming in isolation or waiting for inspiration to strike. The most successful solo founders find their ideas by observing real problems in their daily work, communities, and industries.

This article breaks down exactly how 8 solo developers discovered SaaS ideas that generated significant revenue. You'll see the specific methods they used, the signals they recognized, and the actionable patterns you can replicate.

Why Solo Developer Success Stories Matter

Studying how other developers found their ideas isn't about copying their products. It's about understanding the repeatable patterns that lead to profitable opportunities.

Solo developers have unique advantages:

• They can build quickly without organizational overhead
• They're embedded in technical communities where problems surface
• They understand developer pain points firsthand
• They can validate ideas with minimal investment

The developers profiled here didn't stumble onto their ideas by accident. They used systematic approaches to identify gaps, validate demand, and build solutions people actually wanted.

Before diving into the examples, consider using our data-driven method for finding profitable SaaS ideas to supplement what you learn here.

Example 1: Pieter Levels - Solving His Own Remote Work Problem

The Idea: Nomad List (directory for digital nomads)

How He Found It:

Pieter Levels was traveling as a digital nomad and constantly frustrated by the lack of reliable information about cities. Which ones had good WiFi? What was the cost of living? Where could he find other remote workers?

He started a spreadsheet to track this information for himself. When he shared it in a Facebook group, dozens of nomads asked for access. He realized this personal frustration was shared by thousands of others.

The Method:

• Experienced the problem firsthand while living as his target customer
• Created a minimal solution for himself first (spreadsheet)
• Tested demand by sharing in relevant communities
• Observed strong engagement before building anything complex

Key Takeaway:

Your own frustrations are valuable data points. If you're part of a growing community (remote workers, developers, creators), the problems you experience daily might be shared by thousands of others willing to pay for solutions.

This is a classic example of finding SaaS ideas that people already want to buy by starting with your own needs.

Example 2: Danny Postma - Mining Twitter for Creator Needs

The Idea: Headliner (automated video creation for podcasters)

How He Found It:

Danny spent time on Twitter following podcasters and content creators. He noticed a recurring complaint: creating promotional videos for podcast episodes was time-consuming and required expensive tools or designers.

He saw dozens of tweets asking for recommendations, complaining about existing tools, or requesting features that didn't exist. The pattern was clear—this was a widespread, validated problem.

The Method:

• Monitored social media conversations in his target market
• Identified repeated complaints about the same workflow
• Validated demand before building by counting complaint frequency
• Built an MVP that solved the specific pain points mentioned

Key Takeaway:

Social platforms are goldmines for validated problems. When you see the same complaint from multiple people in a specific niche, you've found a potential opportunity. The key is systematic monitoring, not random browsing.

Example 3: Tyler Tringas - Noticing a Gap in His Workflow

The Idea: Storemapper (store locator for e-commerce sites)

How He Found It:

While doing freelance web development, Tyler noticed that multiple clients needed the same feature: a map showing their physical store locations. Existing solutions were either too expensive, too complex, or required significant customization.

He built a simple solution for one client, then realized he could package it as a standalone product. The problem was common enough across e-commerce sites to support a dedicated tool.

The Method:

• Paid attention to recurring requests in client work
• Identified a feature that multiple businesses needed
• Recognized that existing solutions were overpriced or overcomplicated
• Built a focused tool that did one thing well

Key Takeaway:

If you're doing freelance or agency work, track the features clients repeatedly request. When you see the same need across multiple projects, that's a signal for a potential product. This is particularly powerful for unbundling opportunities.

Example 4: Jon Yongfook - Scratching His Own Itch as a Marketer

The Idea: Bannerbear (automated image generation API)

How He Found It:

Jon was building marketing campaigns and constantly needed to create variations of social media images with different text, logos, or backgrounds. Doing this manually in Photoshop was tedious and didn't scale.

He built a tool to automate his own image generation workflow. When he shared it with other marketers and developers, they immediately saw applications for their own projects.

The Method:

• Identified a repetitive task in his own work
• Built automation for personal use first
• Recognized the solution could benefit others in similar roles
• Validated by sharing with peers before full product launch

Key Takeaway:

Repetitive tasks you perform regularly are excellent candidates for automation tools. If a task takes you 30 minutes and you do it weekly, others in your field likely face the same inefficiency. This aligns with our framework for building weekend SaaS projects.

Example 5: Marc Köhlbrugge - Building for the Community He Created

The Idea: BetaList (directory for startups in beta)

How He Found It:

Marc ran a small tech community and noticed that startup founders constantly asked where they could find early adopters for their products. Meanwhile, tech enthusiasts wanted to discover and test new tools.

He created BetaList as a simple directory connecting these two groups. The idea came from observing a clear mismatch between supply (startups needing users) and demand (users wanting new products).

The Method:

• Observed inefficiencies in his existing community
• Identified a two-sided marketplace opportunity
• Created a simple directory to connect both sides
• Leveraged his community as initial users

Key Takeaway:

If you're active in online communities, watch for marketplace dynamics—situations where two groups need to connect but lack an efficient way to do so. These often make excellent SaaS opportunities because both sides benefit.

Example 6: Andrey Azimov - Solving a Developer Tool Gap

The Idea: Sheet2Site (turn spreadsheets into websites)

How He Found It:

Andrey noticed that non-technical founders and indie hackers frequently asked in forums how to launch simple websites without coding. They had their content in spreadsheets but needed a way to publish it as a website.

Existing solutions required either coding knowledge or expensive website builders with features they didn't need. There was a gap for a tool that did one simple thing: turn a Google Sheet into a website.

The Method:

• Monitored developer and founder forums for repeated questions
• Identified a specific technical gap between tools
• Built a focused solution for non-technical users
• Validated demand through forum engagement before building

Key Takeaway:

Pay attention to questions that appear repeatedly in forums, especially those starting with "How do I..." or "Is there a tool that...". When the same question surfaces multiple times without satisfactory answers, you've found a gap.

Our guide on mining support forums covers this method in detail.

Example 7: Arvid Kahl - Finding Opportunity in a Niche Industry

The Idea: FeedbackPanda (tool for online teachers)

How He Found It:

Arvid's partner was an online English teacher and spent hours each week writing student feedback. She mentioned how all her teacher friends had the same problem—they needed to write personalized feedback for dozens of students daily.

Arvid built a tool to help her create feedback faster using templates and automation. When she shared it with her teacher community, hundreds wanted access immediately.

The Method:

• Listened to pain points from someone in a specific profession
• Researched whether the problem was widespread in that industry
• Built a solution for a well-defined niche
• Leveraged existing community connections for initial users

Key Takeaway:

Talk to people in specific professions about their daily workflows. Teachers, healthcare workers, accountants, and other professionals often have industry-specific problems that generic tools don't address. These niche markets can be incredibly lucrative.

Example 8: Yongfook (Again) - Observing Product Hunt Patterns

The Idea: Hardbound (visual stories for learning)

How He Found It:

Jon Yongfook spent time analyzing what performed well on Product Hunt. He noticed that visual, story-based content consistently got more engagement than text-heavy alternatives. People wanted to learn but preferred engaging, visual formats.

He created Hardbound to transform educational content into visual, mobile-friendly stories. The idea came from pattern recognition across hundreds of product launches.

The Method:

• Systematically analyzed what succeeded on a platform
• Identified patterns in user engagement and preferences
• Created a product that aligned with proven preferences
• Validated concept through the same platform he studied

Key Takeaway:

Studying what succeeds on platforms like Product Hunt, GitHub, or app stores reveals user preferences and gaps. Look for patterns in what gets traction versus what gets ignored.

Our article on mining Product Hunt for gaps expands on this strategy.

Common Patterns Across All 8 Examples

Analyzing these success stories reveals several repeatable patterns:

Pattern 1: They Lived the Problem

Most of these developers either experienced the problem themselves or were close to someone who did. They weren't guessing about pain points—they felt them directly.

Pattern 2: They Validated Before Building

None of them built a complete product in isolation. They tested demand through spreadsheets, forum posts, community sharing, or simple prototypes.

Pattern 3: They Started Narrow

Each tool solved a specific problem for a defined audience. They didn't try to build everything for everyone. Storemapper did store locators. Bannerbear did image generation. FeedbackPanda served teachers.

Pattern 4: They Observed Systematically

They weren't passively waiting for ideas. They actively monitored communities, analyzed platforms, tracked client requests, and paid attention to repeated complaints.

Pattern 5: They Built Quickly

As solo developers, they leveraged their technical skills to create MVPs rapidly. Speed allowed them to validate ideas before competitors noticed the gap.

How to Apply These Patterns to Your Own Search

Here's a practical framework based on these examples:

Step 1: Choose Your Observation Channels

Pick 2-3 places where your target customers discuss problems:

• Reddit communities in your niche
• Twitter hashtags or lists
• Industry-specific forums
• LinkedIn groups
• Product review sites

Step 2: Set Up Systematic Monitoring

Don't browse randomly. Create a routine:

• Spend 30 minutes daily reviewing your chosen channels
• Use tools like F5Bot, Tweetdeck, or RSS readers
• Track recurring complaints in a spreadsheet
• Note the frequency and intensity of problems

Our weekly SaaS idea discovery routine provides a complete schedule.

Step 3: Look for These Signals

High-Value Signals:

• Same problem mentioned by 10+ different people
• People asking "Is there a tool that..."
• Complaints about existing solutions being too expensive or complex
• Workarounds involving multiple tools or manual processes
• Questions that go unanswered in communities

Low-Value Signals:

• One-off complaints without pattern
• Problems only mentioned by beginners
• Issues with free, adequate solutions
• Complaints without willingness to pay

Step 4: Validate Demand Before Building

Before writing code:

• Post about the problem and proposed solution in relevant communities
• Create a landing page describing the tool
• Offer to build it if X people sign up for early access
• Share a simple prototype or mockup

Use our validation checklist to ensure you're asking the right questions.

Step 5: Build the Minimum Viable Solution

Start with the smallest version that solves the core problem:

• Focus on one primary workflow
• Skip nice-to-have features
• Use no-code tools if appropriate
• Get it in users' hands within weeks, not months

Mistakes to Avoid When Following These Examples

Learning from successful developers is valuable, but avoid these common misinterpretations:

Mistake 1: Copying Their Exact Ideas

These examples aren't meant to be copied. The markets they entered may now be saturated. Instead, learn their methods for finding ideas, not their specific products.

Mistake 2: Waiting for the Perfect Idea

None of these developers had perfect clarity before starting. They found decent ideas and improved them through user feedback. Start with good enough and iterate.

Mistake 3: Skipping Validation

Just because these developers succeeded doesn't mean every idea works. They all validated demand before investing significant time. Don't skip this step.

Read about common mistakes in choosing SaaS ideas to avoid other pitfalls.

Mistake 4: Building in Isolation

Each of these developers was embedded in communities where their target users gathered. If you're not part of your target market's community, you'll miss crucial signals.

Mistake 5: Overcomplicating the MVP

They all started with simple solutions. Storemapper was just a map widget. Sheet2Site just converted spreadsheets. Don't add complexity until users demand it.

Why This Approach Works for Solo Developers

The method these developers used is particularly effective for solo founders because:

1. It's Low-Risk

You validate before building, minimizing wasted effort on ideas nobody wants.

2. It's Systematic

You're not waiting for inspiration. You're actively searching in places where problems surface.

3. It Leverages Your Strengths

As a developer, you can build quickly once you've identified a validated problem. Speed is your competitive advantage.

4. It Targets Proven Demand

By observing real complaints and requests, you're finding problems people already know they have—not trying to create demand.

5. It Builds Community Connections

By participating in communities during your research, you're also building relationships with potential early users.

Moving from Idea to Execution

Once you've found a validated idea using these methods, the next challenge is execution. The good news? As a solo developer, you can move faster than teams.

Key execution principles from these examples:

• Build the MVP in weeks, not months
• Launch imperfect and iterate based on feedback
• Stay close to your early users
• Focus on one core feature that solves the main problem
• Add features only when users consistently request them
