Startup ideas you can actually build.

Most lists of startup ideas are either fantasy ("Uber for X") or too vague to act on. These 137 are neither: each one is a specific business — SaaS, micro-SaaS, or B2B — with a named customer, a price point, an MVP scope, and a build prompt you can paste into Cursor, Claude Code, Lovable, or Bolt to start tonight. Small enough for one founder, real enough to charge for.
