Have something half-built? Send it over.
Halfway done and stuck? A Lovable, Bolt or Base44 app, Cursor or Claude code, a Bubble app, or a project a developer walked away from. Within 48 hours you get a written verdict, fix it, finish it or rebuild it, each with a fixed price, and you keep full ownership of the code either way.
- 50+ apps rescued
- written verdict in 48 hours
- fixed price before any work starts
Apps we picked up and got over the line.
Broken builds, abandoned builds and prototypes that had to become real products.

How a takeover runs
- 1
Send it over
Book a call, or invite github.com/douglasmaringa to the repo with read-only access. A ZIP or a test login works too.

48-hour verdict
A written report: every finding ranked critical, important or can wait, plus fix it, finish it or rebuild it with a fixed price for each.
- 3
Your call
Fix it yourself, hand the report to any developer, or say go. Nothing is changed until you approve a price.
- 4
The work and handover
Staging link every week. Nothing merged or deployed without you seeing it. Four weeks of fixes on anything we touched.
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.
Audit and critical fixes
The app mostly works but has holes: exposed data, payments that never cancel, a deploy that only works in preview.
$2,000
to $4,000, depending on what the audit finds
1 week
- Every finding ranked by severity
- Critical ones fixed
- The rest as a checklist any developer can follow
- Read-only access until you approve
Finish it
You got 80% of the way and stalled.
$5,000
to $6,000, depending on scope
2 to 3 weeks
- Keep what works, rebuild what doesn't
- Integrations the AI never finished
- Security rules, Stripe and deploy hardened
- Monitoring and error tracking
- Live, paid product on your own accounts
- Four weeks of fixes after launch
Rebuild it
When the data model is incoherent or a new developer can't read the code in a day.
$6,000
starting from
4 to 8 weeks
- Your prototype becomes the spec
- Version-one pricing applies
- Faster than the first attempt
- Everything in your name
Every price includes a fixed quote, weekly staging links, a documented handover and full ownership.
Straight talk, shipped on time, no surprises.
Fixed what our previous developer couldn't finish.
“We came to JetBuild with an app that had been stuck in development for months. They stepped in, cleaned up the database, fixed the workflows, and got us live. Straightforward communication the whole way through.”
Christopher Clemmons, National Dental Service
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
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.
Questions founders ask first
You should, they're useful. But the tool that built your app has no incentive to tell you its own work is wrong, and it can't see your live database settings, your Stripe dashboard or your deploy config. This is an independent review of the product, the code and the operational setup together, by someone who has shipped production software for years.
No. Read-only is enough for the verdict, and nothing is changed until you approve a fixed price. Access is limited to the repository you share and revocable the moment the report is delivered.
Yes, yours or ours. Your code, product and business are treated as confidential either way and never reused elsewhere.
Lovable, Bolt, Base44, Replit, v0, Cursor and Claude Code output, Bubble, Firebase and Supabase projects, plain React or Next.js codebases, and React Native apps.
Then the report says so, and you keep it. Plenty of founders get a short list of fixes they can do themselves in an afternoon.
