Existing demand and substitute behavior

What this measures

This factor measures whether demand already exists in the wild, judged by what people do rather than what they say. The strongest proof is existing spending, even on a worse option. The second strongest is substitute behavior: the manual workaround, the spreadsheet everyone hates, the competitor people complain about but keep using. Those are all signs the need is already there.

Why it matters

Existing demand means you are competing for a budget that already exists, which is far easier than creating a new one. Creating a market, which means convincing people they have a problem before you can sell the solution, is slow, expensive, and the single most common way ideas fail.

This is why a worse-but-used alternative is good news, not bad. It proves the need is real, shows you exactly what to beat, and tells you where the customers already are. An idea with no existing demand is not automatically dead, but it carries a much heavier burden of proof.

How it affects your recommendation

Strong existing demand pulls the score up and de-risks the whole idea, because it answers the scariest question (does anyone actually want this) before you build anything.

When nothing exists and no one pays, the report treats the idea with caution. You are betting on creating demand, and that bet needs far more evidence than improving on something people already buy. A weak score here rarely sinks an idea by itself, but combined with a vague buyer or a mild problem, it usually means the idea needs more proof before it is worth pursuing.

Example

Compare an app that reminds people to stretch with software that replaces a spreadsheet an entire industry already uses to run a core process. The first has no existing spending and depends on building a brand-new habit. The second steps into proven demand with an obvious substitute to beat. The second idea starts far ahead, because the demand is already there to take.
