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
