"Is my business idea good?" is the wrong question, because the honest answer is almost always "in some ways, and not in others." A better question is: where is it strong, where is it fatally weak, and is the weak part fixable? Here are the 10 questions that answer it, the same ones behind The Signal.
Why "good or bad" is the wrong frame
Ideas are not good or bad. They are strong on some dimensions and weak on others, and one truly weak dimension can sink an idea that looks great everywhere else. A product people love with no way to reach buyers cheaply is not a good idea. A clear buyer with broken economics is not a good idea. So instead of grading the whole thing with one gut feeling, grade it in parts.
Score your idea 1 to 10 on each question below. Be strict. A 9 should be rare. Then look for any single score of 2 or lower, because that one answer often matters more than the average.
The 10 questions to score your idea on
Is the pain real and urgent?
A weak idea solves a nice-to-have. A strong one solves an expensive, urgent, top-of-mind problem people already lose sleep or money over. If nobody has tried to solve this before, that is usually a warning, not a green field.
Is there a clear buyer with money?
Weak: "everyone" or a broke audience. Strong: a specific business or motivated person with a budget who can decide to buy. "Users" is not a buyer.
Will they actually pay?
Weak: they expect it free. Strong: they are already paying for a worse version of the fix. There is a canyon between "I would use that" and "here is my card."
Can you reach them affordably?
Weak: your buyers are scattered and hidden, so every sale costs a fortune in ads. Strong: they gather in known places, communities, or channels you can already tap.
Is there a real reason to choose you?
Weak: me-too, a slight tweak on what exists. Strong: a clear, hard-to-copy angle that makes switching worth it. If your only edge is "better," you do not have one.
Can you actually start it?
Weak: it needs skills, capital, or time you do not have. Strong: you can build and fund a first version now, cheaply. Feasibility for you, specifically, not for an imaginary better-resourced founder.
Is the timing right, and durable?
Weak: a fad, or fading. Strong: a real tailwind, and still needed when the economy turns. Great timing beats a great idea at the wrong time.
Does the money math work?
Weak: thin margins, or it costs more to win a customer than they are ever worth. Strong: high margin, cheap to deliver and to acquire, so profit compounds. This is the dimension founders most love to skip.
Do you have an unfair advantage?
Weak: starting cold with no edge. Strong: an existing audience, a network, or deep expertise others cannot easily copy. The same idea in the right hands scores far higher.
Is the prize big enough?
Weak: a tiny ceiling, or costs that rise one-for-one with every sale. Strong: a large or growing market that scales without your costs scaling with it.
Scared to score yourself honestly?
Most founders cannot, because they are inside the idea. That is the entire point of The Signal: an outside, honest score across all 10 dimensions in three business days, with the reasoning behind each number and a plan for the weak spots. Even if the verdict is "do not build it."

Average the ten. As a rough guide, a strong idea tends to land around 8, a "reshape it first" idea in the middle, and a "do not build this one" idea lower. But the average is only half the story. Apply the fatal-floor rule: if any single dimension is a 2 or below, especially Economics or Willingness to pay, that one answer can override an otherwise decent average. One fatal flaw sinks the idea the average would flatter.
The good news is that most weak scores are fixable without abandoning the idea. A wrong buyer, a wrong price, or a wrong channel can often be changed while keeping what is good. That is what a "reshape" verdict is: same pain, same strengths, different shape.
What a strong idea has in common
- A specific buyer you can name, with a budget and a reason to act now.
- Evidence of willingness to pay, not just interest.
- A cheap, repeatable way to reach more of those buyers.
- Economics that close at a price the buyer has signaled they would pay.
- An edge that fits you specifically, and is hard to copy.
If your idea has most of these, you may be onto something. If it is missing two or three, you have just found exactly what to work on next, which is worth far more than a vague "it is good."
