Coverage
We searched 2 places where competitors live — transparent about what we covered and what we missed.
Should you build this?
- You can ship in 1-2 weeks on $0-20/mo infrastructure
- This weekend: DM 5 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
