How to fix a vibe-coded app, and when not to rebuild it.
If your app was built with Lovable, Bolt, Replit, v0 or Cursor and real customers are about to use it, check four things first: who can see whose data, where your secrets live, whether you can roll back a bad release, and who owns the code. For UK founders, a rebuild is rarely the cheapest safe route.

Six things that go wrong in AI-built apps
A product can work perfectly in a demo and still not be ready. These are the problems a customer's security team, or an investor's technical reviewer, tends to find first.
Data visible to the wrong people
Any logged-in user can read other customers' records. An enterprise buyer's security team will test this first.
Secrets sitting in the code
API keys and passwords stored in the repository where anyone with access can read them.
No backups and no rollback
If a release breaks something, there's no way to undo it, and no copy of the data to restore.
Payments that fail silently
Failed charges that aren't logged go unnoticed until a customer complains.
Nowhere safe to test
With no staging environment, every release goes straight to your customers.
Code nobody can take over
Login or payment code that nobody on the team understands, or accounts and hosting that you don't actually control.
Fix what blocks the next milestone, and leave the rest
Most AI-built products have plenty of imperfections. Only a few of them block what you're about to do, whether that's your first paying customers, an enterprise pilot, investor due diligence or a launch date.
Those are the ones to fix now. Tidying code that works, switching framework or database, and test coverage for features nobody uses yet can usually wait.
Not sure which side your app falls on? That's what the AI Product Readiness Review is for: a plain-English risk map, an honest answer on whether the product can support your next milestone, and a NOW vs LATER roadmap you can act on straight away. It's useful even if you hire someone else to do the work.
Fixed prices, so you know the number first
AI Product Readiness Review
I review your live product against your next commercial milestone and tell you what to do about it.
Production Hardening Sprint
If the review finds blockers, I fix the few that matter for your milestone, with acceptance checks you can see pass.
Onion Sprint
Not live yet? I build the real working core as production code, so there's something solid to build on.
About a week from access to answers
Short call
30 minutes on the product and your milestone. If the review isn't the right move, I'll tell you.
Access
You send read-only access to the code and hosting setup. I'm happy to sign an NDA first, and I don't need access to customer data.
Review
I go through the product against your milestone, covering ownership, security, reliability, performance and deployment.
Walkthrough
You receive the written report and we talk it through, including what to do next.
Fixing a Lovable, Bolt, Replit, v0 or Cursor app
Do I need to rebuild my app?
Only if a rebuild is genuinely the cheapest safe route, which is rare. The NOW vs LATER roadmap exists to stop unnecessary rebuilds.
Does it matter which AI tool built it?
The review covers ownership, security, reliability, performance and deployment, whichever tool produced the code.
Is this just a code review?
No. A code review checks code quality. This checks whether the product can support a specific commercial milestone, and ranks every finding by whether it matters for that.
I'm not technical. Will I understand it?
That's the point. The report is written for founders in plain English, and the walkthrough covers anything that isn't clear.
Is my code safe with you?
I only need read-only access, and I'm happy to sign an NDA before you share anything.
My app isn't live yet.
Start with an Onion Sprint instead. It builds the real core first, so there's something solid to review later.
What's your next milestone?
Tell me what's changed commercially, and when. If a review makes sense I'll say so. If it doesn't, I'll say that too.
