The signal test. You have put something out, maybe only a landing page. Find out whether anyone wants it at all.
Decide what a pass looks like before you start
Write the number down now. Ten payments, twenty replies, five people asking when it ships. Without a number you will call any result encouraging.
Check that someone is already selling this
A competitor is proof that people pay for the problem, not a reason to stop. If nobody sells it, find out why before you assume you are first.
Talk to twenty people who have the problem
Not a survey. Calls or DMs. Write down the exact words they use for the problem, because those words are your landing page.
Put the real price on the page before you build the thing
One sentence, one screenshot, one price, one button. A page people can try to pay for tells you more in a week than a month of building.
Buy twenty dollars of traffic on three platforms
Google, Reddit, LinkedIn, Instagram, TikTok. Set the ad accounts up now, approval takes a day or two. Twenty dollars each tells you whether anyone clicks and which audience is warmest, well before you have built the thing.
Go where they already complainSocial listening
Reddit, Hacker News, Discord servers, niche forums. Be useful there for two weeks without mentioning it, then mention it when it genuinely answers the question.
Message thirty people who described this problem in public this weekFree tools
Offer to set it up for them yourself. Free alerts will email you the moment someone posts the words you care about.
Charge from the first day
Free signups tell you almost nothing. A payment, even ten dollars, means someone chose you over doing nothing.
Not yet
- Paid creators or influencers. You do not know the message yet, so you would be paying people to guess it.
- SEO articles. You do not know which words your customers use.
- An agency. Nobody else can find out for you whether the idea works.
- A logo, a rebrand, a launch video. None of it changes the answer you are looking for.
- Ad spend past the twenty dollar tests.
