Issue #57: 🧠 97,000 Devs Are Using This AI Startup Stack (You’re Not)

Dear Builders,

Right now, most people still think AI is “a chatbot that helps write code.”

Meanwhile, solo founders are quietly building with entire AI teams.

Not in theory.

In production.

Users of today’s skills are shipping 10x faster, running parallel AI workers, and replacing roles that used to require full startup teams.

The scary part?

Most builders still have no idea this shift is happening.

The gap between “using AI” and “orchestrating AI systems” is about to become very expensive. This week’s I show you what the people ahead of the curve are already doing.

Let’s get into it.

🧠 Skill of the Week

Who Built It: Garry Tan

What It Does:
GStack is an open-source framework that transforms Claude Code into a multi-role AI engineering team.

Instead of using AI as a simple coding assistant, GStack gives Claude structured skills, workflows, and persistent context through CLAUDE.md files.

The result?

Claude starts behaving like:

A startup CEO
A senior engineer
A product manager
A QA lead
A designer
An engineering manager

All working together.

This is not “vibe coding.”

This is AI-assisted company building.

How it works in one line:
Claude Code + structured skills + persistent project memory → AI startup team → Faster product shipping.

Why It’s Incredible:
Most people use AI reactively.

GStack turns AI into infrastructure.

The framework includes skills like:

/off-hours → Validates startup ideas before building
/plan → Creates technical architecture and specs
/design → Generates multiple UI directions
/review → Finds bugs and weak logic
/ship → Creates GitHub pull requests automatically

Users report going from 1–2 commits per day to over 20.

That is not a small productivity increase.

That is a different operating system. All open-source and adaptable.

💸 Weekend Challenge: Start Outreach Now

Challenge:
Pick ONE SaaS company, agency, or local business with an outdated website, slow onboarding, or clunky workflow.

Then use GStack to brainstorm how AI agents could improve their business.

You are not building the system yet.

You are identifying opportunities.

Outreach:
Record 5 short Loom videos showing how AI agents could help them move faster, automate workflows, or improve customer experience.

Reply with the word ‘email’ and I will send you an email template you can send out with the loom.

Most founders have no idea what is now possible with AI agents.

Your advantage is simply showing them.

Everything else is noise.
