What you get
Four specialists. One fixed price.
A real build needs a solutions architect, a product manager, a designer, and a senior engineer. Lab Twelve is all of them in one, AI-native and founder-led, with the product judgment and business acumen to make the right calls, so you get the right architecture, a product that is genuinely well designed, and a fast deploy to production, web or mobile, without hiring a team or paying an agency to run one.

Inside the build
What the fixed price buys.
One short conversation in, a production app out. Here is the work underneath it.
The core
An AI that scopes like a senior architect.
It asks the right questions, maps the screens, and shapes a fixed price while you talk, so you start from a real plan, not a blank page.
Architecture chosen for your problem.
The stack and structure that fit what you are building, never a copied template.
Founder-built, with taste.
One senior engineer on it end to end. No handoffs, no offshore, no vibe-coded slop.
Live in production.
Deployed and running, with the source code and handoff docs in your hands.

FAQ
Straight answers.
Fixed price or hourly?
Fixed price for scoped builds. You see the number before you pay. Dev lanes are a flat monthly rate, still not hourly billing.
What is included in a build?
Scoped screens, production deployment, source code, handoff docs, and a mission plan. Add-ons cover extra integrations, rush delivery, or maintenance.
How do revisions work?
Each package includes revision rounds defined in the quote. Scope changes after lock are quoted as adders, never surprise hours.
What is not a fit?
Native mobile apps, heavy compliance (HIPAA/PCI depth), or open-ended 'build whatever' without scope. We say no early.
How fast can you ship?
Launch pages in days. MVPs in two weeks. Timelines are on the quote, tied to scope, not optimism.
Who actually builds it?
Brian — start to finish. I scope it, architect it, build it, and ship it. AI accelerates execution; the judgment, the taste, and the accountability are mine.
