What an unfixed report costs you
Customers you never see
Slow pages, broken phone layouts and emails in spam lose people before they ever contact you.
Risk you can't see
Security gaps in AI-built apps are found by bots long before founders notice them.
Time you don't have
Every evening spent prompting the AI tool to fix what it broke is an evening not spent on customers.

What you'll have at the end
Why JetBuild Studio for this
The diagnosis is done
Your LaunchProof report tells us what is wrong, so fixing starts on day one. That is why these prices are lower than our usual projects.
Fixed prices, small packages
Pick one problem or send the whole report. The price is agreed before we start and never changes without your yes.
Proof at the end
Every package ends with a clean LaunchProof re-scan.
Why not just keep prompting, or hire a freelancer?

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.

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
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.
