The Detective
VerifiedThe Detective provides evidence-based niche analysis tailored to founder skills and constraints.

What is The Detective?
The service begins with user-provided details on skills, budget, languages, and restrictions to generate and filter niche candidates. A specialized evaluation ranks survivors before committing to deeper investigation, refusing options that lack sufficient primary sources while suggesting alternatives. Research produces a ledger of anchored claims followed by a clear verdict of go, conditional go, or no go along with supporting arguments and kill conditions. An independent critic pass then verifies all findings against the original sources to remove unsupported elements. Subscribers receive ongoing access to ranked analyses, watchlists, and export options depending on the chosen plan, with refunds available for unused periods and no long-term lock-in required.
