25(weak)

How we calculated this 40/100

25×30% + 43×45% + 75×25% = 46 → × 1.00 freshness → × 1.00 silver = 40

Final score discounts: freshness drops ~50% per week (29d 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
Only 2 weak rivals shipping — room to differentiate

THINK TWICE

Demand cooling -27% next 14 days (confidence 78%) — momentum is fading
Pain level is LOW — users may not pay to fix this

VALIDATE THIS WEEK

This weekend: DM 5 of the hn users who complained — ask if they'd pay $9/mo for a fix (no build yet)
Next 7 days: ship a 2-page landing site with $9/mo waitlist + "request beta" form — count signups
If 10+ signups: build the smallest version that solves the top 1 pain — defer the rest
