Your Lovable, Bolt, Replit or Cursor app works in the demo. Real users, real payments and real data are where it falls over. We fix it at the root, lock it down and launch it on accounts you own, for one fixed price quoted before we start.

Why AI-built apps stall right before launch
Almost right. Every time.
You prompt, it nearly works, you prompt again. Each fix quietly breaks something else.
Credits drain. Days disappear.
Every tool has its own credits, plans and limits to learn. The meter runs whether you get there or not.
We take the loop off your hands.
We know how these tools behave, so we reach the right result with less trial and error. You never pay for our iterations.
One fixed price. Quoted first.
Nothing more, nothing less. Support is included: defects in what we deliver are fixed at our cost for 30 days after you accept it.

Example
Ship It: from vibe-coded to launched
You got it working, or halfway there, with Lovable, Bolt, Replit, v0 or Cursor. We review it free, fix what breaks at the root, close the security gaps and launch it on accounts you own. No rewrites for the sake of it.
We keep what works and fix what doesn’t
Security, payments, data and backups checked and tested
Moved off the builder’s preview, onto your own domain and app stores
A free review, then one fixed price before work starts
A model tuned to your use case, AI features inside the product you already have, or workflows that run on their own. Built with guardrails, and with a straight answer first on whether AI is the right tool.
AI can make almost anything fast. Without someone who knows what to check, most of it ends up as half-working apps that buckle under real users. We built software for years before AI could write a line of it, and have worked through every wave since. That experience is what you’re hiring, so the AI part is never your worry.
Fast
We use the same AI tools you do, and we know where they shine and where they slip. You get the speed without the mess.
Right
An engineer reads, tests and owns every change before you see it. We fix causes, not symptoms.
Yours
The code is in your name, and the person on your first call is the one doing the work and answering your questions.
Need customers to find it? Marketing, ads, video, social content, websites and landing pages come from our sister studio, Vif Studios. We make the software work. They help people find it.

Questions founders ask first
Something else on your mind? Bring it to the call. You’ll get a straight answer.
Which AI tools do you work with?
Lovable, Bolt, Replit, v0, Base44, Cursor, Claude Code and the rest, plus half-finished builds from any of them. Whatever tool you used, what it produced is ordinary code, and that’s what we work on.
Will you have to rebuild my app?
Rarely. An app that works in a demo usually has plenty worth keeping. We keep what works and fix what doesn’t. If a part would cost more to repair than to rebuild, we explain why and you decide.
My app lives inside the builder. I don’t have the code.
That’s normal. Most builders let you export the code or connect it to a GitHub repository. We’ll walk you through it on the first call.
I’m not technical. Will I understand what you find?
Yes. The review is written in plain English and ranked by risk, and you can ask about any line of it. You never need to read code to work with us.
How much will it cost?
Every job has one fixed price, quoted before we start. The 20-minute call is free, and so is the written review of a vibe-coded app. Once we know what you have and what you need, you get one number in writing. It doesn’t grow, and you never pay for our iterations.
Who owns the code afterwards?
You do, once the work is paid for. It lives in a repository you control, and the hosting, domain and app store accounts are in your name. Open-source parts keep their own licences, and we list them at handover.
What happens if something breaks after launch?
If something we delivered breaks within 30 days of you accepting it, we fix it at our cost. After that, keep us on for changes and new features, or take the code wherever you like.
Do you do marketing, ads or websites?
Not here. Our sister studio, Vif Studios, makes ads, video, social content, websites and landing pages. We make the software work. They help people find it.
Send the link. Get a straight answer
A link and a few lines on what’s going wrong are enough. The call is free, and by the end of it you’ll know exactly what your app needs.
