- 💰 Revenue: Modest — $4K - $9K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.84★ across 625 reviews — below category median.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Low — rating drift -2.22 ★ (recent 50 vs lifetime).
🎯 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 = $111K-$198K. Portfolio play ($30K/mo combined) commands premium.
