Check if an idea has demand

Before you spend money on a new product, service or location, it’s worth finding out whether people actually want it. This guide shows you a simple, low-cost way to check: look for signs people are already searching and paying for something similar, talk to a handful of likely customers, and run one small test, so you decide with evidence instead of a hunch.

Before you start

• Your idea, even if it’s rough.
• The AI tool you normally use, such as ChatGPT, Claude or Gemini. One that can search the web helps.
• A way to reach a few likely customers: existing customers, your social media followers, or local groups.
• A couple of hours spread over one or two weeks.

Skills you’ll need: Interview potential customers, set a measurable test, and judge real commitments. Research alone will not validate demand.

How this helps your brand

A focused test page can explain an offer and capture a genuine expression of interest. Connecting that action to a record and follow-up gives you evidence to judge demand before expanding the idea.

1. 1

   Step 1: Write the idea in one sentence

   Use this pattern: “[Who] has [this problem], and would pay for [my solution] instead of [what they do now].” For example: “Busy dog owners in my town struggle to find midday walks, and would pay for a weekly group walk instead of asking neighbours.”

   If you can’t fill in “what they do now”, think harder about it. Everyone already does something about a real problem, even if it’s putting up with it.

2. 2

   Step 2: Decide what would count as a yes

   Before you look for evidence, write down what result would convince you to go ahead, and what would make you stop. For example: “If at least five of the people I talk to ask when they can book, I’ll run a trial month.”

   Setting the bar first stops you from seeing what you want to see later.

3. 3

   Step 3: Look for signs people already want it

   Spend an hour on desk research. Ask your AI tool to search with the prompt at the end of this guide, and look yourself:

   • Competitors: are other businesses already selling something similar? That’s usually a good sign. It means people pay for it. Look at their prices and reviews, especially complaints, which show what customers wish was better.
   • Searches: type the problem into a search engine and see what it suggests as you type. Google Trends (trends.google.com) shows whether interest in a topic is rising or falling.
   • Questions: look in local Facebook groups, forums and review sites for people asking for this or complaining about the problem.

   Tip: Check anything the AI finds by opening the links yourself. It can misread pages or point to businesses that have closed.

4. 4

   Step 4: Talk to five to ten likely customers

   Short conversations tell you more than any amount of searching. Ask about what they’ve actually done, not what they might do. People are polite about ideas, so “Would you buy this?” almost always gets a yes that means nothing.

   • “When did this last come up for you?”
   • “What did you do about it?”
   • “What did that cost you, in money or time?”
   • “What was annoying about it?”

   Tip: Listen more than you talk. Don’t pitch the idea until the end, if at all.

   A polite answer tells you little

   “Would you buy a midday dog walk?”

   “Sounds great!”

   Ask about the last real occasion

   “When did you last need a midday walk, and what did you do?”

   “Last Tuesday, I paid a neighbour $20 to walk Milo. They cancelled an hour before, so I left work early.”

5. 5

   Step 5: Run one small test that asks for commitment

   The strongest sign of demand is someone taking a real step: signing up, booking or paying. Try one small, low-cost test:

   If you use a test page, give it one offer, one audience, and one action tied to your yes line. A useful first action is registering interest through a short form. Connect that form to an inbox or list you can actually check, state what happens next, and name the person who will respond. A button that opens nothing or a form that only shows success gives you no usable demand evidence.

   Before sharing the page, submit a recognisable test with your own details. Find the saved interest record, check any acknowledgement, and confirm the follow-up owner can handle it. Use the contact-form guide for intake setup. Record where each genuine response came from when you can; keep page visits, registrations, bookings, and paid commitments as different measures. Remove your test from the results.

   After the test period, follow up with the people who agreed to hear from you and record the outcome. Compare the actual commitment level with the threshold from step 2. A registration is evidence of interest, not proof of a sale. If you used a phone call, direct booking link, or in-person pilot instead, record and judge that actual route just as carefully.

   • A post or simple web page describing the offer, with a “register your interest” or “book a place” button.
   • A short trial, like a one-off workshop or a pilot week, for a few early customers.
   • Offering it to existing customers first and seeing how many say “yes, when?”.

   Tip: Only take payment for something you’re ready to deliver, and be clear if it’s a pilot. Refund anyone promptly if you decide not to go ahead.

   Step 6: Compare the results with your yes line

   Go back to what you wrote in step 2. Did you hit it? Be honest. A few friendly “sounds great” comments aren’t the same as people booking.

   If it’s a clear yes, start small. If it’s a clear no, you’ve saved money. If it’s in between, change one thing, such as who it’s for or how it’s offered, and test again.

   Below your line? Use the result to decide whether to stop or change one thing and test again.

I’m thinking about a new idea for my small business and I want to check whether there’s real demand before I spend money. Please be honest, not just encouraging, and explain in plain English.

My idea in one sentence: [Who] has [this problem], and would pay for [my solution] instead of [what they do now].
Where: [your town, region or online]
My current customers: [a short description]

Please:
1. Search for businesses already offering something similar near me or online. List them with links, and what customers praise or complain about in their reviews.
2. Suggest search terms and online places where people might be asking about this problem.
3. Write five questions I can ask likely customers about what they’ve actually done, not what they might do.
4. Suggest two small, low-cost tests that ask people for real commitment.
5. Help me set a clear “yes” and “no” result before I start.
6. Point out the biggest risks or reasons this might not work.

Don’t make up figures, market sizes or statistics. If you can’t find something, say so.

For a page-based test, specify the page’s offer and main action, the real form/booking destination, acknowledgement, follow-up owner, and a pre-launch submission test. Keep visits, interest registrations, bookings, and paid commitments separate. Exclude test records and connect the observed commitment level to my yes/no threshold. Do not imply that a signup guarantees demand or a sale.
