PMF Signal
Runs a $9 sourced research report on your business idea, willing to say pass.
PMF Signal generates a 16-section research report on one business idea, scored against your own cash, hours per week, and skills, ending in a BUILD, PIVOT, or PASS verdict instead of encouragement. The scoring happens before the writeup, so the number constrains the prose rather than the other way around, and every report discloses which sources were reachable and how many quotes were fabricated (always zero, per its own claim). Run against its own operator's real constraints, the tool has returned BUILD only 3 times out of 13 published reports, all unedited. It costs $9 per report and takes about 15 minutes, with results emailed when ready.

What holds up
- +Publishes its own track record — 3 BUILD, 6 PIVOT, 4 PASS out of 13 reports on the operator's own ideas.
- +Scores pain, timing, market ceiling, and founder fit independently before writing the verdict.
- +$9 per report and about 15 minutes — cheap and fast enough to run on more than one idea.
Mind the limits
- −Only 13 reports published as a track record so far — not a large sample to judge accuracy from.
- −Each report costs $9 — testing several ideas back to back adds up.
