Sample result from a fictional test idea.
Most ideas fail because nobody checked if anyone wanted them.
You spend three months building. You launch. Silence.
It's rarely a bad idea. It's an untested one. The people who get this right put a page and a few pounds of ads in front of real strangers first, and watch what happens.
Demandcheck does all of that for you, in about an hour of your time and a few coffees' worth of ad spend.
How it works
From idea to live test in under an hour.
No code, no designer, no ads expertise. You answer questions. It does the rest.

Describe your idea
A short guided form: what it is, who it's for, the problem it solves, and how you'd charge. Ten minutes, plain English.
Step 2 of 4Who is this for?
Be specific. "Busy parents" is weaker than "parents of under-5s who both work".

You have one shot and no team. Spend your next three months on the idea that already has a queue, not the one you hope will.
Side-project builders

Small business owners
Thinking about a new service or product line? Test it with real customers before you hire, stock up, or print the flyers.

Questions
Straight answers.
Do I need to know how to code?
No. You fill in a form and review what's generated. If you can write an email, you can run a test.
Who pays for the ads?
You do, directly to Google, with a daily cap you set. Most tests get a clear read on £5–£10 a day for 5–7 days. We never mark up ad spend.
What if my idea gets a weak signal?
That's a result, and a cheap one. The report tells you whether the problem is the idea, the angle, or the audience, and suggests one change to test next. Many ideas pass on the second attempt.
Which call to action should I use?
Start with a waitlist if you just want to know whether anyone cares. Use pre-order or a small deposit when you want to know whether they'd pay. Book-a-call works for services and higher-priced ideas. You can switch and re-run: the same page with a stronger ask is often the most useful second test.
Can I edit the landing page?
Yes. Every headline, benefit and image is editable before you publish, and you can change it while the test is running.
How long does it take?
About an hour to set up and launch. Most tests show a usable signal within 3 to 7 days, depending on your budget and how niche the audience is.
Do you own my idea?
No. Your idea, your page, your signups, your data. Export all of it at any time.
