- 💰 Revenue: Marginal — $0 - $500/mo · MICRO tier · indicative confidence, trajectory unclear.

- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: last update 293d ago — slow cadence.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $3K-$6K. Portfolio play ($19K/mo combined) commands premium.
