From Side Project to Micro-Product: Shipping Small Paid Tools with AI

[Image placeholder — hero] Replace with from-side-project-to-micro-product-hero.webp when ready.

Graveyard of unfinished side projects vs one tiny shop with an “open” sign.

Field notes, not financial advice. Most products make little money; plan for that and treat wins as upside.

TL;DR

  • Building is cheap now. Distribution isn’t. Assistants like Cursor can get you a working v1 in days. They won’t get you customers.
  • Narrow wins. One job, one type of user, one clear payoff.
  • Charge from day one. Free users tell you what’s nice. Paying users tell you what’s needed.
  • Ship ugly, fix what customers complain about.
  • Pick a problem you’ll still care about in a year. Products are slow.

Step 1: Find the problem (not the idea)

Ideas are cheap. Look for pain that people already spend money or time on.

Where to lookWhat to notice
Your own jobThe spreadsheet you rebuild every month
Forums & communities”Is there a tool that…?” posts
Existing clunky toolsOne-star reviews that ask for the same thing
Your service workTasks you do for every client the same way

Best source: repeated service work. If you’ve done the same job for five clients, you already know the spec, the buyer, and the price. That’s where the services path leads.


Step 2: Shrink it

Too bigMicro-product
”AI assistant for small businesses""Turns supplier PDF invoices into a clean CSV"
"Learning platform""Flashcards from your own lecture notes, in Japanese"
"Marketing suite""Rewrites one product page for three marketplaces”

Test: can you explain it in one sentence and demo it in 30 seconds? If not, cut.


Step 3: Build v1 in a week or two

  • Boring stack. Whatever you ship fastest in. Hosted services over self-managed servers.
  • AI assistant for the grunt work: scaffolding, forms, tests, glue code. You own the architecture and the edge cases.
  • Must-haves only: the core job, sign-in if needed, payment, a way to contact you.
  • Skip: dashboards, teams, settings pages, dark mode (fine, maybe dark mode).
  • Add AI features only where they do the core job. “Now with AI” is not a feature.

Watch your costs. If each use calls a paid model, know your per-use cost before you set a price.


Step 4: Price it

ModelGood for
One-time purchaseTemplates, small utilities, no ongoing costs
SubscriptionTools used every week or month, with ongoing costs
Usage-based / creditsHeavy model-API costs per use

Price on the value of the job (“saves two hours a month”) rather than your build time. You can almost always lower a price. Raising it is harder.


Step 5: The first ten customers

  • Hand-sell. Message the people from Step 1 who described the pain. Offer a demo.
  • Build in public. Short posts about what you’re building and why; people buy from people.
  • Go where the buyers are, not where builders hang out. Your market isn’t other indie hackers (unless it is).
  • Do things that don’t scale: onboard every user yourself, fix their bug the same day.
  • Ask every user: “What almost stopped you from paying?”

Kill or keep

After a few months, be honest:

SignalDo
Paying users, and they’re asking for moreKeep. Double down on the one feature they use.
Users, but no one paysWrong price, wrong buyer, or not painful enough. Change one thing.
No users after real effortKill it. Write down what you learned. Next problem.

A dead project with notes is a lesson. A dead project with no notes is just a tombstone.
