Opportunity score 46/100 Solid
DEV-TOOLS sector avg: 58 -12 Top 75% (12 cards)
GapMine track record: 254 predictions proven avg 34d early →

25(weak)

53(moderate)
FeasibilityBased on existing supply count (inverse percentile — less supply = higher feasibility), build difficulty, and source diversity.

26d old Strong Demand + Supply or Trigger
How we calculated this 46/100
25×30% + 53×45% + 75×25% = 50 → × 1.00 freshness → × 1.00 silver = 46
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
  • No direct competitors yet — first-mover window open
THINK TWICE
  • No paid evidence AND no competitors — could mean "no market" rather than "open market"
VALIDATE THIS WEEK
  1. This weekend: DM 5 of the reddit:saassolopreneurs 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: build the smallest version that solves the top 1 pain — defer the rest
