A few weeks ago Gary Tan published something that most people scrolled past.
He open-sourced his entire AI setup. Not a summary or a keynote slide deck.
The actual workflow he uses to build products.
For context, Gary runs Y Combinator. If you do not know what that is, Y Combinator is the startup accelerator behind Airbnb, Stripe, Dropbox, Coinbase, and Instacart.
Basically, if a startup became a household name in the last 15 years, there is a decent chance YC had a hand in it.
Gary sits at the centre of all of that. So when he says "here is exactly how I build," you probably want to read it.
He called it gstack. And I want to explain what it actually is, because most of the coverage got lost in the technical details and missed the real point.
Here is what gstack does in simple terms.
Instead of opening one AI tool and asking it to do everything, gstack splits the work across multiple AI agents that each have a different role.
One thinks like a CEO
One thinks like a designer
One thinks like an engineering manager
They coordinate with each other. You bring the idea, and the system helps you think through what to build, how it should work, and what to do first.
Think of it like having a team living inside your laptop.
You can quickly go from Idea to launch without waiting six months or spending money you do not have yet.
The reason this matters for business owners who are not developers is actually pretty simple.
For a long time, building felt locked behind technical skill. If you could not code, you had two options.
Learn everything yourself, which most people never actually did. Or depend entirely on someone else, which meant losing time, money, and usually some of your original vision along the way.
What Gary published starts to close that gap. Because what he is really showing is that the person who wins is not necessarily the one who can do every task.
It is the one who can think clearly, give good direction, and keep things moving. That is a skill business owners already have. They just have not had the tools to apply it this way until now.
Here is what really got me though.
He did not have to share this, he could have kept it internal. A lot of people in his position would have.
Instead he put it on GitHub and basically said, here is how I operate, take it. That tells you something about where things are heading.
When people at that level start publishing their actual setups, it usually means the window for getting ahead of it is still open but it is not going to be open forever. Somewhere a 22-year-old is already building a business on top of this.
The practical thing I would take from all of this is straightforward.
Stop worrying about whether you are technical enough. Start getting better at one specific thing, which is turning your business ideas into clear instructions and clear priorities. Because that is what these tools need from you.
Pick something in your business that should exist but does not yet.
A better onboarding flow
An internal tool your team would actually use
A customer portal that saves you three hours a week
Then ask yourself what you would tell a small team to build first if you had one available right now.
The tools are getting better every month. The people who know how to direct them are still rare.
The advantage is still available.
But not for long.
