$3K in 45 Days Selling “Tiny AI Tools” Anyone Could Build

  • Ryan Doser

  • Marketing Consultant
  • $3,000+ in his first 45 days

Forget building an entire app. The fresh play is selling a “tiny AI tool” – a Claude Skill, basically: a recipe that makes the AI do one task your way, every time.

Marketing consultant Ryan Doser packaged ~25 of his own into a $99 bundle, sold it from his site, and cleared over $3,000 in about 45 days – basically all profit 🤑

No paid ads. What stuck with me, from Chris Koerner’s writeup

…he didn’t build anything new… He just took what he was already doing every day and turned it into a product.

Ryan’s a marketer with an email list, so that part’s not the magic.

The magic is who else could pull this off 👀

Chris reckons it’s wide open, and Ryan rattles off a few people who’d have something to sell 👇

  • A baseball-card trader could build a tool that reads photos and flags resale value
  • A gardener could build one that turns your location into a planting plan
  • A youth soccer coach could build one that spits out custom practice drills
  • A nurse could build one that catches medical-billing errors

These are off the top of his head – just to show how wide open it is. You’d be packaging hard-won experience so the AI gives expert answers, not generic ones 🧐

And building one is almost too easy. Open the Claude app, talk through everything you know about a task, and have it write the Skill up for you.

Ask yourself what you know that takes others years to figure out, then start there. Starting out, price a single tool at $19–29 and a bundle of three to five at $49–79 – then grow from there 😎
