I Think Most Founders Are Looking for Opportunities in the Wrong Place

For the last few weeks, I've been obsessed with a question:
Where do startup opportunities actually come from?
Most advice says:
Follow trends
Watch funding rounds
Study hot markets
Brainstorm ideas
But the more founder conversations I read, the more I notice something different.
The same frustrations keep repeating.
Different founders.
Different industries.
Different products.
But similar complaints:
"I have traffic but no conversions."
"People sign up but don't stay."
"I keep building but nobody buys."
"I don't know where users are coming from."
One complaint is noise.
A hundred similar complaints is a signal.
And signals are often more valuable than ideas.
Lately I've started wondering:
What if opportunities aren't hidden in trends?
What if they're hidden inside frustrations that refuse to disappear?
I'm building a small experiment around this idea.
Not to generate startup ideas.
But to identify the patterns underneath recurring founder problems.
Curious:
What's one frustration you keep seeing over and over again among founders, builders, or customers that nobody seems to be solving well?
I'm collecting recurring founder frustrations for a pattern research project. What's one problem you keep seeing but nobody seems to solve well?
