Problem solved

AI-based idea review tools are predominantly biased toward agreeing with the user, since they are trained to be helpful and cooperative. Because of that, founders receive false validation instead of an objective assessment. PMF Signal solves this by judging an idea against a founder's actual constraints and issuing a BUILD, PIVOT, or PASS verdict, with every claim in the report carrying a source so the user can check the facts. The verdict is computed from independent section scores and the tool has a proven track record of saying no, making it a reliable counterweight to optimistic AI.

Use cases

• Pre-product-market fit research on a startup idea
• Evaluating an idea before allocating cash, time, or engineering effort
• Testing whether to pivot or keep iterating on a current side project
• Uploading an existing pitch or business plan document for re-evaluation
• Understanding a market's minimum viable scale and competitor density
• Getting a sourced, checkable research report rather than an AI write-up

Audience

• Startups
• Business Users

Pros

• Openly argues back and is built to say no
• Every claim has a source, quote, and link
• Scores sections independently before composing the verdict
• Provides results in about fifteen minutes
• Record shows only 3 of 13 reports came back BUILD

Cons

• Paid: $9 per idea
• Focused on solo founders, may not fit larger product teams
• Verdict is based on publicly available web research, not private market data
• Requires the founder to input accurate constraints for a relevant assessment
