Somebody is already charging for this

You have projects sitting in the ledger in different states of built — a finished site nobody visits, a half-built app you stopped touching six months ago. Before any of them get a verdict, they need one fact that costs nothing but an hour of searching: does anyone already charge money for something like this?

The honest instinct runs backwards. Finding nobody feels like clean air — an open field, nothing in your way. Finding four competitors feels like the field is already taken. Both readings are wrong, and this lesson is about why.

Why “no competitors” is usually bad news

Paul Graham’s argument, made against a decade of watching startups, is that founders overrate the danger competitors pose and underrate the danger an empty market poses. Competitors rarely kill a company — running out of a reason to exist does. So when a market looks big and obviously worth entering, and yet nobody has bothered to compete in it, the honest read is not opportunity. It is that everyone who looked already concluded there is no money in it.

“A crowded market is actually a good sign” is the line worth sitting with (Graham, How to Get Startup Ideas). Crowding is evidence that people are already paying, which is the one fact no amount of thinking in isolation can manufacture. A finished sports-guides site with zero traffic and zero visible competitors charging for anything adjacent is not evidence of a gap you found first. It is evidence the gap was checked and closed.

The signal hierarchy, weakest to strongest

Not every sign of demand is worth the same. In order of how much you should trust it:

• Search volume. People typing a phrase into a search engine proves curiosity, not willingness to pay. The cheapest signal to find and the easiest to talk yourself into overweighting.
• Forum complaints. Someone venting that nothing solves their problem is a real person with a real problem — but venting is free, and plenty of vented problems never convert into a wallet opening.
• A competitor existing. Somebody built the thing. That is a stronger bet than a forum post, but building is cheap too; plenty of side projects exist that never earned a dollar.
• A competitor charging. Somebody put a price on it and asked strangers to pay. This is the first signal that has actually been tested against real money changing hands.
• A competitor charging and still alive two years later. Somebody put a price on it, and the business survived long enough that a fluke launch or one enthusiastic cohort can’t explain it away. This is the strongest signal on the list, and the one worth spending the most time confirming.

Where to look, free tools only

None of this requires paid research tools. A search engine, the app store listing pages for iOS and Android, and the search box inside whatever forum or subreddit your users would actually hang out in will surface most of what exists. Search for the problem, not the product name you would have picked — you are trying to find who else is already being paid to solve it, and they will not have named it the way you would.

For a half-built recipe app for kids, that means searching app stores for the shape of the product (not a brand you would invent), reading the one-star and five-star reviews on anything that comes up (reviews are where people explain what they paid for and what they resent about it), and checking whether the developer has shipped updates recently enough to still be maintaining it.

What a pricing page tells you about a market

A competitor’s pricing page is denser with information than almost anything else you can read for free. The number itself tells you what this market has already decided something like your idea is worth — which is a better starting price than anything you would guess from cost-plus reasoning. The tiers tell you how the market segments itself: what a casual user pays for versus what makes someone upgrade. And how long that page has existed — a copyright year in the footer, a blog with a multi-year posting history, cached snapshots showing the same price a year or two ago — is the cheapest way to check whether you are looking at a business or a launch that quietly stopped.

Now run it: the Demand gate, against the real shelf

This is the Demand gate run for real, against real projects. It is the cheapest gate in the course — an hour of searching per project, no tools you have to pay for.

What this does not cover

Demand evidence tells you whether anyone wants this. It says nothing about what keeping it running actually costs you once it exists — hours answering support email, dependency updates, an app-store review process that does not pause for your evenings. That number is next, and most builders have never actually measured their own.
