What this is costing you
Months at 80%
Every week stuck is a week without customers or revenue.
The AI tool fights back
Each fix breaks something else, and the prompts get longer and the results worse.
Money already spent
Credits, time and a developer who disappeared, with nothing live to show.
Why it usually happens
- The app outgrew what the AI tool can hold in its head
- A database structure that doesn't fit the product any more
- Integrations (payments, email, auth) half-finished
- No tests, so every change can break something unseen
Which one it is on your site is the first thing we find out. Send us your report.
What it costs
Every project is a fixed price agreed in writing before we start, with half up front and half at launch. Not sure which fits? The call is free and you leave with a recommendation and a number.
Finish the app
When the AI tool keeps breaking things, a developer takes it from here.

Keep what works
We don't restart from zero unless it's cheaper for you.
You talk to the developer
No account manager in between.
Why not just keep prompting, or hire a freelancer?
| Keep prompting the AI tool | A freelancer | JetBuild Studio | |
|---|---|---|---|
| Knows what's wrong | Guesses from your description | Starts from scratch | Starts from your LaunchProof report |
| Price | Credits, then more credits | Hourly, open-ended | Fixed before we start |
| Checks its own work | No | Sometimes | Clean re-scan as proof |
| Knows AI-built apps | It built them | Varies | 50+ rescued |
| You own everything | Yes | Usually | Always |

One senior developer, not an agency relay.
When you work with JetBuild you talk to the person writing the code. No account managers, no handoffs, no telephone game between you and the build. That's why fixed prices are possible, and why 90% of clients come back.

How it works
- 1
Send your report
Use the form below. Your LaunchProof report comes with it, so we already know what's wrong.
- 2
Fixed price in 24 hours
We look at the report and your site and reply with a fixed price and a start date. No call required.
- 3
We fix it
Read-only access until you approve. You see every change on a staging link before it goes live.
- 4
Re-scan as proof
We run LaunchProof again and send you the clean result, plus a short record of what changed.
How every project runs
Fixed price before we start
You know the full number upfront. Never hourly surprises.
Weekly staging links
You click through the real build yourself. No curated demos.
Documented handover
Any future developer can pick your project up.
You own everything
Code, data, accounts and infrastructure are yours at the end.
Fast, reliable, and actually understands Bubble at a deep level.
“JetBuild delivered exactly what we scoped, on time, with zero hand-holding needed. They understand Bubble at a production level, not just getting things to work, but building them properly.”
Brian Luerssen, Founder at DraftBit
Rescued our app after our first developer disappeared.
“Our first developer ghosted us halfway through the build. JetBuild picked up the project, restructured the database, and launched it in under 3 weeks. Should have started with them.”
Rachel Simmons, Founder at PivotOps
Built our entire booking system and payment flow from scratch.
“We needed a booking platform with Stripe payouts and role-based dashboards. JetBuild scoped it clearly, built it fast, and it worked on day one. No back and forth, no surprises.”
Marcus Webb, Co-Founder at GreenRoute Logistics
“Fixed what our previous developer couldn't finish.”
Questions founders ask first
Then we say so before you pay anything. Start with the $500 code health check if you're not sure.
Because the LaunchProof report has already done the diagnosis. We know exactly what to fix, so a job that would normally start with a week of discovery starts on day one.
We tell you before doing anything extra, with a price. The fixed price you agreed never changes without your yes.
Lovable, Bolt, Base44, Replit, v0, Cursor and Claude Code output, Bubble, Supabase and Firebase, plain React and Next.js, and React Native.
Always. Everything stays in your accounts and your repository.
