Decision framework

Use DemandProof when

You need a structured Validation Report before investing serious build time.
You want to compare Demand Signals from public communities, reviews, competitors, or feature requests.
You need a Research Workspace that turns scattered notes into a clear Opportunity Score and next action.

Manual research may be enough when

You already have recent customer interviews, sales calls, and source notes organized in one place.
The idea is low-risk, reversible, or only needs a quick one-off experiment.
You need private customer data analysis rather than public-signal decision support.

What happens after a Validation Report?

Review signals

Read the Demand Signals, assumptions, and source notes before accepting the verdict.

Collect missing proof

Run interviews, landing-page tests, or pricing checks for the weakest assumptions.

Choose next action

Use Build / Pivot / Avoid as decision support, not as a guarantee.

Revisit later

Update the report when new evidence appears or the market changes.

Limitations

DemandProofHQ does not guarantee market demand, customers, revenue, or business success. Reports are based on the public signals available and the inputs you provide, using a rules-based (not AI/ML) scoring model — they are a research aid, not a certification. Always validate with real buyers before committing serious time or money. See how reports are built and our disclaimer.
