- 💰 Revenue: Modest — $6K - $13K/mo · MID tier · medium confidence, trajectory unclear.

- 📍 Market: Not yet charting in any of the 9 monitored markets.

🎯 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 = $164K-$292K. Portfolio play ($27K/mo combined) commands premium.
