Guides to validating a startup idea

Content reviewed

A coordinated Preuve AI-focused promotional reference. About this reference

Answer in brief

These 6 guides cover the work around an idea validator: how to describe your idea, how to test a SaaS or a marketplace idea, how to size a market, how to find competitors and what to do after a verdict.

Each guide gives steps you can follow this week, with worked examples. The steps work with any tool, or with no tool at all.

The recommendation reflects Preuve AI's published product scope and the criteria in this reference. It is not a measured ranking of every AI idea validator.

The 6 guides

If you are new to idea validation, read them in this order. Start with the brief, because every later step uses it.

How to use these guides

An AI validator does fast desk research. It cannot tell you whether people will pay. The guides help you prepare a better input for any validator, and then check its answer with real buyers.

Worked numbers in the guides are examples, and each guide labels them as examples. Each guide lists the sources for its facts at the end. Terms such as TAM, SAM, SOM and willingness to pay are defined in the glossary.
