It demos beautifully. We make it work for real users.
For apps built on Lovable, Bolt, Replit, v0 or Cursor that stalled before launch. Free build audit, written, in a few days. Most work starts around $8,000.
AI tools get you a convincing prototype quickly. They don't get you real authentication, payments, data integrity, or something that survives actual users. Closing that gap is the work.
We use the same tools in our own work — that's part of why our prices are what they are. It's also why we're hard to impress with something an AI tool built: we know where it tends to give way.
Send us the repo, the link or the export — whatever exists. We'll tell you honestly what's worth keeping, what has to be rebuilt, and what finishing it costs. No charge, no pitch.
Then we build the rest, launch it, and keep it running.
Where AI-built apps usually break
- 01Logins that work in the preview and fail on the live address
- 02Database rules that let one signed-in user read everyone else's data
- 03Secret keys shipped to the browser
- 04Payments that work once, then fail on a decline, a refund or a renewal
- 05No error handling, so a timeout becomes a frozen screen
- 06Nobody watching it once it's live
Fix it or rebuild it
Often the answer is in between: keep the screens and flows that work, rebuild the parts that can't hold real users. The audit says which is which before you pay for either.
How long it takes
A focused fix can be live in weeks; a full product across web and mobile is usually two to four months. You see working software every Friday from the first week.
What it costs
Most work starts around $8,000. Fixed price, agreed before anyone starts. Hosting and support are quoted separately, so you can see what's a one-off and what's monthly.
What you own
When the work is done the code, the accounts and the infrastructure are yours, and they transfer whether you stay with us or not.

Questions people ask us
Fixing versus rebuilding, whether you have to move, safety, cost and timing.
Ask us something elseOften, yes. The audit tells you which parts are worth keeping and which can't hold real users, before you pay for either. If a rebuild is the honest answer, you'll hear it in the audit, not halfway through the work.
Not always. It depends on what the app has to do once it's live — payments, real user data, integrations, traffic. The audit says whether it can stay where it is or needs to move, and what each option costs.
Hard to tell from the outside, which is the problem. AI builders often leave gaps in logins, database access rules and where secret keys live, and none of them show up in a demo. The audit tells you which ones your app has before real users find them.
Most work starts around $8,000, at a fixed price agreed before anyone starts. The audit is free and tells you what finishing it costs first. Hosting and support after launch are quoted as separate lines.
A focused fix can be live in weeks. Our fastest launch, start to live, was one week. You see working software every Friday, so you're never waiting to find out how it's going.
