- 💰 Revenue: Modest — $6K - $13K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.43★ across 2,122 reviews — strong (top 10%).
- 📍 Market: Not yet charting in any of the 9 monitored markets.

- ⚠️ 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 = $158K-$280K. Portfolio play ($22K/mo combined) commands premium.
