Opp Radar
Beatable markets — 2026-10-13
An automated radar sweeps 4 app stores, Reddit, Hacker News, Product Hunt, Flippa and Google search data — and finds proven demand stuck on weak, abandoned or dead products. First to ship wins.
🎯 Beatable markets — weak supply, live demand, proven money
Niche score = weak/thin supply × live demand × willingness to pay. "% charge" = incumbents that monetize; CPC = what advertisers pay per search click (people only bid on searches that make money); trend = search interest, last 3 months vs the 9 before.
