Software with recurring revenue is the dream model, every customer you keep makes next month easier, but it's also the most crowded. Solo founders don't win by building "another tool"; they win by going narrow into a specific vertical the funded players ignore, and out-caring them on the details. High margins, but trust and retention are earned slowly.
