You get a business idea.
You’re pumped.
You start building.
A few weeks in, you’re knee-deep in tools, tasks, and tabs. You finally launch… and nothing happens.
No traffic. No sales. No interest.
That’s the silent killer of most online businesses.
Not a bad product. Not a lack of effort.
Just no validation.
But building before testing is gambling with your time.
What if, instead, you could validate like a startup consultant without hiring one?
The Problem with Most Online Business Ideas
Most people love the spark of an idea.
They skip the part where you ask, “Does anyone even want this?”
Validation sounds boring. Market research feels slow.
So they Google a few things. Maybe ask ChatGPT what it thinks.
Then they start building anyway.
Weeks later, reality hits.
They were solving a problem no one had, for a person they didn’t understand, in a market they never studied.
That’s what this prompt is built to fix.
