100 SaaS product ideas in one spreadsheet. Each row: the problem, an MVP you can ship in weeks, what to charge, how hard it is to build (1-5), how crowded the market is (1-5), and where to find the first customer. Every idea names a concrete buyer and a concrete price — no "AI fitness app" filler. The ideas come from primary research, not brainstorm loops: a Solana/x402 payment gap scan, agent-marketplace probes, scraping operations, and small-business workflows in Southeast Asia. About a quarter are crypto rails (invoice reconciliation, private payroll, dispute and tax primitives — documented gaps with no incumbent), the rest are plain SaaS: scraper monitoring, cron and cert monitoring, WhatsApp reminders for salons, payout reconciliation for marketplace sellers. The top 20 get a full page each: who buys, why now, MVP scope, price, and the exact first-customer channel. Files: CSV (100 rows) + Markdown companion + cover.
