Overview

A small subscription app solving one recurring workflow problem for a narrow customer group is the classic AI-accelerated build — tools like Claude Code and Cursor make the technical build genuinely faster than it used to be, but distribution (finding customers who'll actually pay) and technical reliability at scale remain the real risk. A wide income range ($200–$20,000+/mo) reflects how much outcomes vary; most of that variance comes from validation before building, not the build itself.

Why it works

Recurring subscription revenue is genuinely attractive compared to one-off project work, but distribution (finding customers who'll actually pay) and technical reliability at scale are real, significant risks that determine most of the outcome variance. The build itself is now the easy part; validation before building is where most attempts actually fail.

Subscription

How to start

Find a repeated problem you or people you know hit often enough to pay to solve.
Interview 10-20 prospects to confirm the problem is real and painful, not just mildly annoying.
Validate willingness to pay explicitly — ask for a number, don't just ask 'would you use this'.
Build a simple landing page describing the solution before writing any product code.
Pre-sell to a handful of the interviewed prospects to confirm demand before building.
Build the smallest version of the product that solves the core problem, using Claude Code or Cursor.
Add the AI feature that makes it meaningfully better than a manual spreadsheet or existing tool.
Beta test with the pre-sale customers and fix what actually breaks their workflow.
Charge from day one, even a small amount — free users rarely convert or give honest feedback.
Measure retention closely; a subscription product lives or dies on whether people keep using it.
Improve onboarding relentlessly, since most micro-SaaS churn happens in the first week.
