💰 Revenue: Marginal — $0 - $500/mo · MICRO tier · indicative confidence, trajectory unclear.
⭐ Quality: 3.21★ across 22 reviews — weak — significant quality concerns.
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: last update 304d ago — slow cadence.
⚠️ Risk: Moderate — 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 = $1K-$2K. Portfolio play ($120/mo combined) commands premium.
