Why do people say they like my idea but don't buy?

Positive feedback vs buying intent

Early feedback is often politeness. People don't want to hurt you, and imagining a product is far easier than paying for one. So "I love this" tells you almost nothing about whether anyone will buy.

Buying intent looks different. It costs the person something.

• They ask when they can have it, or what it costs, without being prompted.
• They describe what they do today to solve the problem, and it's clearly painful or expensive.
• They agree to pay, pre-order, or put down a deposit.
• They introduce you to the person who holds the budget.
• They give up time: a second call, a trial on their own work, a setup session.

Why the gap happens

Usually it's one of three things. The problem exists, but it doesn't hurt enough to change behavior. The person who likes it isn't the person who pays. Or the offer is unclear: they like the idea but can't see what exactly they'd get, when, and for how much.

What to do next

Go back to the five most enthusiastic people and make a specific offer: this, for this price, starting this date. Their answer is the first data you have. A clear no is useful. A vague "maybe later" is a no.

If nobody takes a concrete offer, look at the problem before the product. Ask what they did the last time this problem came up. If the answer is "nothing much," the pain isn't there yet.

Common questions

Is positive feedback worthless?

Not worthless, but weak. It tells you the idea makes sense to people. It doesn't tell you anyone will pay. Treat it as permission to ask for a commitment.

How do I ask for money before the product exists?

Describe exactly what they'll get and when, name a price, and offer a pre-order or a refundable deposit. People who need it will say yes. People being polite will find a reason to wait.

What if friends and family love it?

Ignore that signal. They're the least likely people to tell you the truth and usually not your customers.
