Answers / finishing an AI-built app

Can someone help finish my AI app's last features?

Short answer, yes. I take the app you got most of the way with an AI tool and finish the parts that are hard to finish alone, the payments, the auth, the admin, and the security and launch hardening. You keep ownership. It starts with a free Leak Check, so you see what is left before you commit to anything.

The short answer

Yes, someone can. This is the exact thing I do. I take the app you got most of the way with an AI tool and I finish the parts that are hard to finish on your own. The payments, the login and permissions, the admin screens, the error handling, and the security and launch hardening that a demo never needs but a real product does. You keep ownership and you keep moving. The work is fixed scope for a fixed fee, not cofounder equity, and it starts with a free Leak Check that reads your live app from the outside so you can see what is actually left before you commit to anything.

Why it stalls near the end

The AI got you far, then the last stretch got hard.

Most of the founders I talk to are in the same spot. The AI got them further than they expected, further than most people believe is possible, and then it stalled somewhere near the end. The homepage looks finished. The demo works when you drive it. But the payment flow breaks on the second card, the reset-password email never arrives, there is no admin view to refund a customer, and nobody has checked whether a stranger can read another user's data.

None of that is a failure. It is just the shape of the last stretch, where the work stops being about making it look right and starts being about making it hold up.

The tricky part is that this stretch is the thing AI is worst at and the thing you can least afford to get wrong. A model will happily generate a checkout page that looks correct and quietly skips the webhook that confirms the payment. It will write auth that works for you and leaks for everyone else. Those are not typos you can spot by reading. They are the failures that show up the week after launch, in production, with a real customer's money or data in the middle of them. That is the work worth paying a human for, and it is the same reason we wrote a longer guide on taking over a vibe-coded app.

How it works

A path that starts free and never asks for blind trust.

Every step is designed so you learn something real before you spend anything. You can stop after any of them.

1
Free Leak Check
Point it at your live URL. It reads what is exposed from the outside, no code access needed, and tells you the truth about where you stand.
2
Ship Check, if it is worth a longer look
A paid, ranked audit of everything between you and a safe launch. Optional, and only if the Leak Check says there is more to see.
3
Finish the work, fixed scope
Payments that clear, auth that holds, the admin you need, the rough edges filed down, and the launch hardening. Quoted up front, so you know the number before I start.
4
Launch, then your call
When it is live I can stay on and watch it as it grows, or hand it back clean and documented. You decide which.
Who this is for

Close, but not comfortable shipping yet.

This is a fit if you built something real with Lovable, Bolt, Replit, v0, Cursor, or a long stretch of Claude, and you are close but not comfortable pressing launch. It is a fit if you are non-technical and you have hit the point where you cannot tell what is safe and what is not.

It is not a fit if you are still changing the idea every week, because paying to finish an app you are about to rewrite is spending the budget you will want later. And if the honest answer is that you are fine to launch as is, I will tell you that, because I would rather you hear it from me than from a customer. The reason this is a real offer and not a pitch is that the first step costs you nothing and tells you the truth. Run the Leak Check, read what it finds, and decide from there.

FAQ

Finishing an AI-built app, straight answers.

Yes. Finishing an AI-built app is a normal, well-understood engagement, not a rescue. A senior engineer reads what you have, finds the parts that are incomplete or unsafe, and completes them, the payment flow, the auth and permissions, the admin screens, the error handling, and the launch hardening. You keep ownership of the code the whole way through.
Almost always the same short list. Payments that actually clear and reconcile rather than just look right, login and permissions that hold for strangers and not just for you, an admin view so you can run the business, real error handling, and the security work a live product needs but a demo never does. AI tools are strong at the visible surface and weak at exactly the parts everything rests on.
No. The first step is a free Leak Check that points at your live URL and reads what is exposed from the outside, with no code access needed. You only share the codebase if you decide to move forward, and even then you keep full ownership. Nothing about the first step asks you to trust anyone on faith.
The finishing work is quoted as a fixed scope for a fixed fee, so you know the number before any work starts, and it is a project fee rather than cofounder equity. Engagements usually begin small, with a free Leak Check on your live app, then an optional paid Ship Check that ranks everything standing between you and a safe launch. You only commit to the build once you have seen what is actually left.
Then I will tell you that. The free Leak Check exists partly to catch this case, because plenty of apps are closer to safe than their owners fear. If the honest answer is that you can launch as is, you will hear it from me rather than from an angry customer a week later. An answer page that never says keep your money is just an ad.
