Lovable developer for the part after the prototype.
You got 80% of the way in a weekend. We do the last 20%: Supabase security rules, Stripe webhooks, auth that survives a custom domain, a deploy that works in production, or a clean move off Lovable Cloud onto infrastructure you own.

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
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

Questions founders ask first
Yes. We work in the GitHub repo Lovable syncs to and leave notes in the codebase so the next prompt doesn't undo the security work. If you'd rather leave Lovable, we can move you off it entirely.
Yes. It's the migration we're known for: 1,800 tables, 6,000 policies, 200,000 files and 5,000 users moved live with zero downtime. The full write-up is on the blog.
Invite our GitHub account with read access and you'll have a written verdict within 48 hours, with a fixed price for each option.
Yes. If the prototype proved the idea, a version one built properly on Next.js and Supabase often costs less than fixing everything the prototype guessed at. Your Lovable app becomes the spec.
