Everyone is using AI to make a demo. You will make something people pay for.
Most people use AI to make a demo. You will leave with a working product real people can pay for, built alongside someone who has done it.

Small cohort. Direct feedback on your real build. You leave with something live.
Join the waitlistWhat you get everywhere else
A demo
- Looks great in a screen recording.
- Falls over the moment a real user touches it.
- No way to take payment.
- You cannot explain why it broke.
What you leave here with
A product
- A working product, deployed and live, not a screenshot.
- A way to take payment, so the thing can actually make money.
- The judgement to know when the AI is wrong and how to fix it.
- A repeatable process you can use for the next idea, and the one after that.
Six weeks of building
We build the whole way through
Week 1
Pick the right thing to build
Most projects die because the idea was too big or too vague. We scope yours down to something you can finish and someone will pay for.
Week 2
From prompt to working skeleton
Get a real app running fast using the current tools. Cursor, Claude, the workflow that actually holds up past the demo.
Week 3
The 20 percent AI gets wrong
Auth, data, edge cases, the parts that break in front of users. Where you stop vibing and start thinking.
Week 4
Make it look like you meant it
The difference between something that looks AI-generated and something people trust with their card details.
Week 5
Payments and going live
Take real money, deploy properly, and ship it where people can find it.
Week 6
First users, first feedback
Get it in front of real people, read what they tell you, and fix the right things.
The AI you will actually build
Hands-on AI skills, not buzzwords
By the end you can do these yourself, on your own product, without a course holding your hand.
Work with an LLM API
Wire a model into your app and write prompts that hold up in production, not just in a demo.
Add RAG
Connect your own data so the app answers from your documents and facts, not the model's best guess.
Build evals
Set up tests that tell you when the AI is right, and catch it the moment it starts being wrong.
Choose and fine-tune a model
Pick the right model for the job, and fine-tune one on your own data only when it earns its keep.
Ship simple agents
Give the model tools so it can take actions, not just chat, without letting it run wild.
Cost, latency and guardrails
Keep it fast, affordable and safe once real users are hitting it every day.

- YesYou can give a few focused hours a week for six weeks.
Skip it if
- NoYou want a certificate and nothing else.
- NoYou are looking for a free overview of what vibe coding is.
- NoYou will not put in the build hours between sessions.
Why learn this here
I do not teach this from theory. I run the products. Slim Prep is the training I wish I had when I was figuring it out the hard way. I am not teaching you to build a product from a slide. I am teaching you the way I actually do it, the parts that work and the parts that bite.
users on a product I shipped and still run
paying customers, all won without paid ads
businesses built and running at once
Straight answers
There are, and some are good. They teach you the tools and leave you with a demo. This is not that. You are buying a small cohort, direct feedback on your actual build, and time with someone who has shipped and sold real software. The free course gets you to a prototype. This gets you to something live that can take payment. If a prototype is all you want, take the free one with my blessing.
No. You describe what you want and the AI writes most of it. What you do need is the willingness to read what comes back, run it, and fix the parts that break. We teach you exactly where that judgement matters.
Early-bird closes when the first cohort fills. Price goes to $2,000 after.
Small on purpose. The whole value is that your real work gets looked at, so seats are capped and they go quickly.
Most people get to something live and small. The aim is a real, finished thing, not a huge one. You also leave with a process you can run again on your own.
Build the thing you keep meaning to build.
The first cohort starts September 2026 and seats are capped. Join the waitlist and we will email you before the early-bird price closes.
