TimingBased on trigger event count, event freshness (14d window), and growth forecast. Percentile against all active cards.
25(weak)
SeverityBased on pain intensity level, mentions (full-corpus percentile), and paid-evidence count (log scale).
61(moderate)
FeasibilityBased on existing supply count (inverse percentile — less supply = higher feasibility), build difficulty, and source diversity.
50(moderate)
26d old Strong Demand + Supply or Trigger
How we calculated this 49/100
25×30% + 61×45% + 50×25% = 47 → × 1.00 freshness → × 1.00 silver = 49
Final score discounts: freshness drops ~50% per week (26d old), and grade weight reflects how many of the 3 signal types (demand/supply/trigger) we found.

Should you build this?

YES, if
  • You can ship in 1-2 weeks on $0-20/mo infrastructure
  • 1 signal of willingness to pay in the evidence pool
VALIDATE THIS WEEK
  1. This weekend: DM 5 of the reddit:hermesagent users who complained — ask if they'd pay $9/mo for a fix (no build yet)
  2. Next 7 days: ship a 2-page landing site with $9/mo waitlist + "request beta" form — count signups
  3. If <10 signups in 7 days: kill it · the demand isn't there at this price
