The New Startup Playbook: Build Fast, Scale Later
Why Vibe Founders Are Winning (And How You Can Too)

THIS WEEK’S STORY
There’s a new playbook emerging and if you’re here, you're already living it.
I see it all the time with the new wave of "Vibe Founders" building apps today.
It goes something like this:
Come up with a strong, vibe-driven idea, not from spreadsheets but from intuition.
Build a very lightweight MVP using AI, no-code, or minimal code (maybe a weekend or two).
Launch it fast to a small, engaged audience, not some massive PR campaign.
If it sticks? THEN start layering in product, brand, community, and scaling ops.
The new startup playbook:
Build a V1 in a few weeks
Launch on TikTok
Get customers
THEN fundraise
THEN build team
THEN become a “real company"
You don’t need millions in funding, an army of engineers, or a 50-page business plan anymore.
You just need a vibe, the courage to ship fast, and the creativity to learn on the fly.
Vibe Coding isn’t just for apps, it’s for companies now too.
And the early movers are going to eat everyone’s lunch.
If I had to start from $0 today, this is exactly how I’d build a $100k/month startup with AI:
You start with something boring and valuable. Maybe it’s writing onboarding flows for SaaS companies. Maybe it’s building landing pages that convert.
You charge between $2,000 and

THIS WEEK’S TIP
How to Prompt AI When Building iOS Apps
If you're using AI to build your app (and you should), you need to prompt it properly, otherwise you’ll end up frustrated, fixing dumb errors for hours.
Here's the simple guide:
Pick the right stack for your goal
If you're serious about a fully native iOS app → Learn the basics of SwiftUI.
If you want to build once and launch fast on web + mobile → Learn the basics of React Native or NextJS.Write a simple Product Requirement Doc
Before you even open ChatGPT, write a few bullet points:What features you want
What the "done" version looks like
Step-by-step instructions (one task per chat!)
Provide small working examples
Instead of saying “Build an onboarding flow,” say “Here’s a working login screen. Add a 'Create Account' button.”Use version control
Always have a way to roll back. Even basic Git saves you from AI-generated messes.When you get stuck, reset the chat
Don’t keep hammering away in the same thread.
Open a fresh chat, clearly explain:What you expected
What went wrong
Error logs or screenshots
Mastering how you talk to AI is just as important as learning SwiftUI or React Native.
It’s your new co-founder; treat it like one!
