For a long time, I searched for startup ideas the same way most founders do:

• AI idea generators
• “100 SaaS ideas” lists
• Product Hunt launches
• Trend reports

I’d find an idea, get excited, spend weeks building it, then realize nobody really wanted it.

Eventually, I realized something:

The problem wasn’t my execution.

The problem was that I was starting with ideas instead of demand.

So I changed my approach.

Instead of looking for startup ideas, I started looking for complaints.

Because every complaint is evidence that:

• A problem exists
• Someone cares enough to talk about it
• Someone is spending time, money, or effort dealing with it

Over time, I developed a simple framework.

Whenever I find a complaint, I ask 4 questions:

1. How often does this complaint appear?

One person complaining isn’t interesting.

Fifty people complaining about the same thing is.

Patterns matter more than opinions.

2. Are people already trying to solve it?

I look for:

• Spreadsheets
• Manual workflows
• Workarounds
• DIY solutions

Workarounds are one of the strongest demand signals.

People rarely build complex workarounds for problems they don’t care about.

3. Are people willing to pay?

I look for phrases like:

• “I’d pay for this.”
• “What’s the best tool for…”
• “Is there software that can…”
• “How are you solving this?”

Those signals are worth more than likes or upvotes.

4. Who already serves this market?

A lot of founders avoid markets with competitors.

I do the opposite.

Competitors usually mean customers exist.

The question isn’t whether competitors exist.

The question is:

What’s missing?
The process works.

But doing it manually is painfully slow.

You end up spending hours reading Reddit threads, reviews, forums, and social media discussions, then even more time researching the market and competitors.

That’s why I built PainBase.

I wanted a tool that could help me:

• Discover real user pain points
• Generate AI research reports
• Analyze competitors
• Validate opportunities faster

The goal isn’t to generate startup ideas.

The goal is to discover demand.

So the next time you’re looking for a startup idea, don’t ask:

“What should I build?”

Ask:

“What are people already struggling with?”

That’s where the best opportunities usually start.
